Here at MBT, we want to ensure that you are fitted correctly in order to get the full benefits from the technology in the sole. We therefore do not sell our product online, but instead ensure that our retailers are trained on a regular basis to provide an individual fitting service for you and show you how to stand and walk best in MBTs.
MBTs start from a size 35 to 41 2/3 (European) in the women’s range and 41 to 47 (European) in the men’s range. MBT sizing is different therefore your size will vary depending on the style. Please visit your nearest MBT stockist for further advice.
The technology of the MBT is in the sole, and that remains the same in every style. The uppers vary to accommodate different style needs and preferences, allowing MBTs to be worn morning, noon, and night.
The new Dual Board (lower) sole provides the wearer with the same benefits as the classic one – the only difference between the two sole constructions lies in the feeling for the wearer. While still curved, the Dual Board construction reduces the heights of the sole by approximately 8mm, offering a new slender look and additional style choice to customers.
Yes, there are 10 years of intensive study and research on MBT. Research guides our product development and provides proof of the benefits of wearing MBTs. We’ve done research to direct the evolution and quantify the effectiveness of MBTs, and the scientifically proven physiological benefits are impressive and desirable to anybody ready for a more healthful and energetic life.
The size range of MBT defines the target group. (Size 35 2/3 -47). Each age group can benefit from the technology of physiological footwear.
The more you wear your MBTs, the more your body will feel the benefits. Try to wear your MBTs as regularly and as often as possible.
MBTs replicate walking on an uneven surface; imagine playing squash, etc. on uneven ground. Therefore, it’s not suitable to wear MBTs for these specific sports or for agility sports, in general. MBTs can be used when exercising with free-weights, step and aerobics. These activities should only be taken up once you are use to walking correctly in MBTs and have reached a good fitness level (approximately 12 weeks).
MBTs should be used solely as a walking shoe for the first 8 to 12 weeks (depending upon your fitness level). Once you have gotten used to this then you can start to expand your use into other areas such as training in the gym on the treadmill, stationary bike or eliptical walker. MBTs are not a stability shoe so should not be used for agility activities such as aerobics or fast running.
Yes, MBTs are perfect for jogging, as demonstrated in the video/DVD. MBTs are suitable for training but not for competitions. Always make sure that you are comfortable walking in them first, beginning with the recommended time. MBT Academy recommends that you wear your MBTs for 12 weeks before you begin to use them for sport.
MBTs are absolutely great for typically healthy people who stand all day. They are designed to decrease pressure to the skeletal system. A regular shoe’s impact enters directly through your heel, traveling into your joints and skeletal system. In comparison, MBTs transfer the shock behind the heel and body. We suggest rocking back and forth in your MBTs while you stand. This activity increases circulation, reduces shock to the body, and helps you to stand for longer periods of time — without discomfort and pain.
MBTs have great benefits before and after pregnancy. If you have been wearing MBTs prior to the pregnancy then you can continue to do so as the body will have adapted to the changes. If you have not worn MBTs before then we recommend that you wait until after the birth. This is because the body is experiencing significant changes during pregnancy so it is important to keep these to a minimum. Do not continue to wear MBTs during pregnancy if there is any discomfort associated with wearing them. As the pregnancy progresses, swelling in the feet can occur which can affect the fit of the MBTs leading to undue pressure on the structures of the feet. MBTs may be indicated for use during pregnancy as part of treatment of back pain related to the pregnancy and for ante-natal fitness purposes. If you are under the supervision of a medically qualified women’s health specialist such as a physiotherapist or midwife and are pregnant and wish to start wearing MBTs during pregnancy then consult with your specialist as to whether MBTs would be suitable.
MBT is a medical device class 1 in the EU and several health insurance companies reimburse the cost of MBT. The concept is backed up by the leading sport medical and biomechanical institutes in the world and leading medical specialists recommend the application for muscular skeletal problems such as:
Back, hip, leg and foot problems; and Joint, muscle ligament and tendon injuries.
If MBT is used as secondary therapy for existing basic health conditions its application must be supervised by a medically trained specialist.
Yes, they were designed specifically for the treatment of back pain, rehabilitation and for the prevention of injury. Over 70% of people in developed countries will experience low back pain at sometime in their lives. It is most common between the ages of 35-55 years. Pain is non-specific in 85% of people.
MBTs will help to improve posture and muscle activity of the leg and core muscles and therefore, help to take strain off the back.
An individual walking in MBTs automatically attains a more upright posture rather than a forward leaning gait. This leads to an increased activation of the lumbo-sacral musculature due to the alteration of trunk angle relative to the pelvis when wearing MBTs. When muscles start to work harder they can be painful. This should normally resolve within a few days.
Do not try to work through the pain however. Use your MBTs within your comfort level and build up the amount of time you wear them as your comfort allows.
Sciatica, or pain that radiates down the back of the leg, is a symptom of a problem usually stemming from the low back, therefore it is considered as a back problem.
Symptoms, pathology and radiological appearances are poorly correlated. Acute low back pain is usually self-limiting and the majority of people will have recovered within 6-12 weeks. Activity speeds symptomatic recovery, reduces chronic disability and leads to less time off work than rest.
MBTs also affect the angle of the trunk relative to the pelvis; this places the lower back to load optimally through the pelvis and hips, rather than the forward lean individuals have with conventional footwear.
MBTs also affect the lumbo-sacral musculature, which also helps to strengthen the lower back and aid recovery. MBTs should be seen as a tool that may help to resolve the pain associated with the condition of sciatica. If back or leg pain persists, then an individual should see their doctor to rule out more serious conditions such as infection, tumor, fracture, inflammation, osteoporosis or rheumatoid arthritis.
In certain cases, MBTs should not be worn with this condition. That includes when the sciatica is very acute or irritable and easily set off by any activity. If this is the case then it is best to wait until the symptoms of sciatica settle down before using MBTs.
MBTs reduce the pressure in the heel and mid-foot and therefore will be helpful for problems such as heel spur, plantar fasciitis, Achilles tendonitis and arthritis. MBTs also reduce the joint forces in the ankle thus taking strain off the foot-ankle complex. MBTs are also useful for Metatarsalgia as they will reduce the pressure to the front of the foot.
Yes, MBTs activate the muscles in your feet therefore help rebuild fallen arches. It is very important that the MBT are used correctly to achieve this.
Yes, as long as you find the MBTs comfortable then they are suitable for people with high arches.
MBTs can be helpful for plantar fasciitis as they reduce the pressure in the arches of the feet where the plantar fascia lies. You will need to gradually practice standing and walking in MBTs, and over time they will help to gently stretch the plantar fascia whilst protecting it and strengthening the muscles which support it. In some cases it may be neccessary to wear orthotics (insoles) in your MBTs - particularly if you are used to wearing orthotics already. If unsure, check with the person that prescribed them for you.
The MBT functions like an active orthotic rather than passive support. In many cases you do not need to use orthotics in your MBTs as the structure of the shoe will substitute for the function of the orthotics. MBTs also serve as a proprioceptive tool thereby enhancing the foot and ankle stabilising musculature.
It is possible to combine MBTs with orthotics but this should only be done under the supervision of a specialist podiatrist or physiotherapist. If in doubt, please consult the MBT Academy and/or your medical specialist.
MBTs dynamically alter loading through the foot, ensuring that the load is distributed evenly through the foot from the moment of heel strike until the foot leaves the ground at toe off. This mimics walking barefoot. Conventional shoes concentrate loading through the heel and then through the forefoot, culminating in a push-off from the big toe potentially causing pain in those individuals with osteoarthritis affecting the big toe (a condition also known as hallux rigidus or bunions).
MBTs will reduce loading through the knee. We also know that walking in MBTs benefits the muscles acting around the knee. In particular, MBTs cause a stretch of the hamstring muscles and also specifically cause activation of the quadriceps. These features assist the management of anterior knee pain. It is always advisable to contact a medically trained MBT specialist (doctor, physiotherapist, osteopath, podiatrist or chiropractor) for a definitive diagnosis.
Clinical studies at Calgary University and Sheffield Hallam University have demonstrated that MBTs reduce loading through the hip, knee and ankle. This may well reduce the pain in these joints due to osteoarthritis. MBTs also activate knee and ankle musculature and stimulate proprioceptive feedback around these joints. All of these factors may be beneficial. They will certainly be of benefit in the pre-operative period.
Provided you are already familiar with MBT they can be seen as a valuable tool in postoperative rehabilitation. It is advisable, however, that they are not worn until 6 - 8 weeks post operatively as the potential risk of a fall in this period would dislodge the artificial joint. It is recommended that MBTs be used post-operatively in conjunction with supervision provided by a rehabilitation specialist such as a physiotherapist.
We recommend MBTs for arthritis, but you should always consult a medical specialist first.

A varicose vein is due to the failure of a valve, which prevents backflow in superficial venous vasculature. MBT usage cannot correct for this mechanical venous malfunction. What MBT does is increase the blood flow in the deep calf veins, thereby minimising superficial venous return.
Cardiac rehabilitation improves coronary risk factors and reduces the risks of major cardiac events in people after myocardial infarction. MBTs may therefore be used as part of a cardiac rehabilitation programme. Together with education, medication and lifestyle modification as indicated.
Depending on the severity of the altered or abnormal vascular supply MBTs may be an aid to improving peripheral circulation in the affected limb. It is important to realise, however, that as MBTs may increase muscle activation initially the compromised circulation in the affected limb may lead to an increase in pain. This is due to an inadequate blood supply.
MBTs can be worn by individuals with both insulin dependent and non-insulin dependent Diabetes Mellitus. Wearing the MBT stimulates blood flow to all muscle groups in the legs. It is also a potent aid to proprioception thereby, stimulating the nerve supply to muscles, joints, ligaments and tendons in the lower limbs. This is of benefit and may help individuals who are prone to develop the neuro-vascular complications of Diabetes Mellitus.
The aims of treatment after the acute phase of a stroke are to minimise impairments, disability and secondary complications with minimal adverse effects from treatment. To this end MBT may be beneficial. The MBT is a potent activator of vascular flow in the lower limb and has also been shown to have a significant impact on muscle activation in the gluteals, hamstrings and calf musculature.
We know the MBT gives active proprioceptive feedback with every step taken.
It should always be remembered, however, that MBT is fundamentally an unstable footwear device. With prolonged supervised usage it should aid rehabilitation but initially there may potentially be an increased risk of falls if used without supervision.
Multiple Sclerosis is a chronic inflammatory disease of the central nervous system. In Europe and North America it is the most common cause of neurological disability in young adults with an age of on set between 20-40 years. It has a prevalence of 1 in 800 people. In 90% of affected individuals the disease process is relapsing and remitting in nature.
Randomised clinical trails have demonstrated that outpatient rehabilitation reduced MS symptom frequency and fatigue. Clinical studies have failed to demonstrate the benefits of exercise on disease progression. MBT may therefore, be worn in individuals who have MS as part of their normal rehabilitation programme. The MBT will aid proprioception and muscle function.
Yes, MBTs are suitable as a training tool for people who suffer from chronic fatigue syndrome/ME. As they increase the work your muscles are doing you will need to pace yourself with your MBT use and experiment very gradually to determine your optimal time using them.
MBTs should not be worn in the early stages following diagnosis of a deep vein thrombosis. This is because the increased muscle activation of the calf musculature may lead to the clot becoming dislodged and leading to a potentially fatal pulmonary embolus. Most individuals who have a DVT are put onto the drug Warfarin and once stabilised and told by their doctor to resume exercise, MBTs may be worn.
Yes, you may treat the MBT upper like you would any other high-end footwear purchase. However, do make sure that you protect the sole construction by not allowing any foreign materials to come in contact with the Masai Sensor.
The sole construction and Masai Sensor of MBTs should not be exposed to aggressive liquids (acids or disinfectants), salt, oil, manure, blood, protein, grease, fertilisers or mud. If they are exposed to these substances they must be cleaned as soon as possible.
To wash MBTs thoroughly inside and out, use a soft brush (old tooth brush/nail brush) and clear mild liquid hand soap with water up to 30°c. Remember to dry them upside down so that the water drains away from the sole
It is best to clean your soiled MBTs immediately so that dirt does not become ingrained
No. Due to the complex nature of the technology in the Masai Sensor, MBTs will disintegrate if put in the washing machine, and they cannot be repaired.
MBTs can be worn in the rain, but they should be left to dry thoroughly. To dry them, put them upside down near (but not on) a radiator, allowing the water to drain away from the mid sole and the Masai Sensor. If left wet or damp, the adhesive may start to separate and become brittle.
MBTs should not be put in an oven, microwave, or under a grill! Believe it or not people have tried, and it has never ended well!

Things to check when you have blisters while wearing MBTs:
Do you have the right size? MBTs should be snug on the instep, tight on the heel and comfortable on the toe. If there is any slipping at the heel it is possible that they are too large for you, or if your foot feels as though it is struggling to move but can't, it may be that they are too small. In either case, you should return to your stockist to check the fitting.
Are your laces tight enough? It might seem obvious that you need to do up your shoes tightly but this really does make a difference. Pull the laces firmly from the very front of the foot to ensure that the foot is held snugly and does not slip. You will usually gain about an inch of lace by doing this, for most people this will be enough to make sure they stay snug.
What socks are you wearing? The type of socks you wear is very important as the wrong ones will increase heat and friction which may cause blisters. We recommend that you wear good quality sports socks made from a breathable material that cover the ankle completely (i.e. not ‘trainer socks’).
Extra measures If the above things do not have any effect, you may need to try gel pads as some people find that the shape of their ankle might not be compatible with the shape of the MBT inner heel, for example their heel or ankle may be thin or bony.
Yes, there is good evidence that MBTs are safe and effective for treatment of ankle sprains. In the UK alone, there are 6,000 ankle ligament sprains per day. Approximately 30% of these individuals will have symptoms of pain, stiffness and recurrent sprains if not managed appropriately.
The big benefit of MBTs in rehab is the proprioceptive stimulus, which they provide. They are also potent activators of the ankle stabilising musculature.
Many individuals who have ligament injuries are given ‘wobble boards’ to assist rehab. These are used for 20-45 minutes per day. In effect, the MBT acts like a permanent wobble board due to its inherent instability and can comfortably be worn every day, thereby strengthening the ankle in the long run.
* Morton’s Neuroma (symptoms can be aggravated due to increased blood flow and muscle activity in feet) * Irritable Sciatica (symptoms of sciatica which are set off easily by activity) * Skin Ulcerations * Peripheral Neuropathy with loss of sensation * Third Trimestre Pregnancy: do not start wearing MBTs in the third trimestre of pregnancy * Abnormal Pregnancy (including twins) * Spinal Stenosis (narrowing of the spinal canal or spaces (foramina) where nerves exit) * History of unexplained falls * Surgery - wait 12 weeks.
MBTs are manufactured from particularly hard-wearing materials and are known for their durability. A simple care routine will ensure MBTs have a long life! Masai GB Ltd. ensures the highest quality control is applied to our product. With each pair of MBTs we remedy against manufacturing faults for a period of 6 months from the date of original purchase.
Faulty MBTs must be returned to your retailer along with proof of purchase. If you are unable to provide proof of purchase your warranty is not valid. In order to establish that there is indeed a manufacturing fault, your retailer will send your MBTs to our official MBT repair, Service Centre Bolton Bros. Ltd. for assessment. If Bolton Bros. Ltd. (or the retailer) determines that the MBTs have been used without adherence to the care instructions, or not used in the correct way, the warranty will not be valid.
No warranty can be given for consequential damage resulting from a delayed return or from repairs or alterations carried out by unqualified persons. Please note that the warranty does not apply to general wear and tear. Repair work carried out by our MBT Service Centre does not come with a warranty.
Contact the Customer Service department 020 7684 4633 / customer-service@uk.mbt.com to discuss your query; they will be able to advise you as to your options.
The lace locks have been discontinued. However, you can still continue to wear your MBTs without lace locks as long as you ensure they are laced tightly as with our other styles.
We can provide you with a set of laces. Please send a stamped addressed envelope and a cheque for £2.50 made payable to Masai GB Ltd to the following address: 83 Curtain Road, Unit 2a, London EC2A 3BS. Please also include a note with your contact number & stating which MBT style you want the laces for. Your laces will then be despatched by return post provided they are in stock. Should they not be in stock, we will hold on to your cheque and envelope until they come back in stock at which point they will be despatched and your cheque will be cashed.
MBTs do not come in traditional width fittings, however, our range is split into three main segments of narrow, medium, and wider styles. Please visit your closest MBT stockist for a personal fitting.

Although we don’t carry 100% vegan styles as there may be traces of animal products used in the glues, there are some models that are made of 100% synthetic materials.
Please return to your MBT stockist who will offer you further assistance.
You will be fitted with the correct size, which should be snug on the instep, tight on the heel and comfortable on the toe. You will then be shown how to walk and stand correctly in them so that you can get the full benefits from the MBT technology. The whole process takes at least 10 minutes.
In order for you to get the full benefits from your MBTs, you need to have the correct size; they must be snug on the instep, tight on the heel and comfortable on the toe.
Also, you will see that the sizing of MBTs is different from regular shoes so the size you usually wear in an ordinary pair of shoes isn't necessarily what you need in MBTs to get the correct fitting as described above.
If you are at all unsure of the fitting of your MBTs please return them to your stockist.
Tip: Wear your MBTs only inside the house for the first few days to ensure you have purchased the right size. This way if you do need to get a different size your retailer might exchange it depending on their exchange/return policy.
Yes you can. Please ensure you are comfortable and confident in your MBTs beforehand.
The suitability of MBT is not based on age but on fit and ability to walk properly and comfortably in the MBTs. As long as there is a good fit and there is adequate strength around the foot and ankle to walk with a good gait pattern, MBTs are appropriate. In general, there is no upper age limit but children younger than ten may have difficulty with the current range of MBTs. If in doubt, consult with MBT Academy.
The aching sensation experienced by some individuals, especially in the first few days of wearing MBTs, is a well recognised phenomenon in any individual undertaking a new exercise programme and is known as delayed onset muscle soreness. It normally settles after wearing MBTs for approximately five days.
For the first week, wear MBTs between ½ to 2 hours per day. Then gradually build up over time until they can be comfortably worn for over 2 hours by which time muscle activation and proprioceptive feedback are sufficiently attuned to wear MBTs all day, every day. If applied as a medical or therapeutic tool, make sure you refer to a health specialist. The amount of time you are able to tolerate wearing the shoes will depend upon your initial level of fitness and health.
No, the introsession that you receive at the point of purchase is enough for you to know how to walk and stand correctly in MBTs.
However, there are optional classes available to customers who may feel that they need some motivation or would like to try something new; these include Pilates classes and walking groups. More details about these classes can be found on this website.
When you put your foot into the MBT, tap your heel on the ground with your toes up in the air to make sure that your foot is right at the back of the shoe. Then, if you have a style with laces, be sure to pull them from the front of the foot so that there is no slack in them, this will ensure that the foot is held snugly and will prevent rubbing.
The soft parts of the sole are sensitive to aggressive liquids containing salt, oil, manure, blood, etc.
Wash and dry your MBTs as soon as possible if they become muddy and dirty. Incorrect care or use can cause the Masai Sensor to deteriorate and the layers to separate. The leather styles should be polished prior to wearing them and the suede/nubuck styles should be protected with a spray prior to the first wear to help prevent wear and tear.
The life span of a pair of MBTs is dependant on how well they are looked after as they are made of a complex and sensitive material. However, if cared for as per the care instructions, your MBTs can last many years.
Osteoporosis is a condition of thinning of the bone which is helped by weight-bearing exercises and resistance training. Walking is an important part of any program for osteoporosis and MBTs are the perfect walking shoe. In addition to their comfort, they will increase muscle activity which also helps to build bone. If you have balance problems then MBTs may not be suitable without medical supervision, otherwise, MBTs can be used to help combat the effects of osteoporosis.
MBTs can be a helpful part of a rehabilitation program to improve balance. This should be done under the supervision of a Chartered Physiotherapist or other medically qualified individual. Some conditions affecting the vestibular system within the inner ear, such as Meniere's Disease or Vertigo, may be aggravated by wearing MBTs.
If in doubt, consult with a medical specialist or MBT Academy.
This is an area MBT is currently carrying out clinical research in. If the problem is mild to moderate, then the MBTs may be an effective part of rehabilitation for the problem. This is because the Achilles and calf muscles will be stretched and eccentrically strengthened during MBT use. However, in more severe cases where there is swelling of the tendon, the stretch provided by the MBTs may be too much and cause aggravation. In this instance, do not use MBTs.
MBTs should always be comfortable to wear. If in doubt, consult with a medical specialist.
Yes. Case studies performed on three people with below-knee amputations and on a person with an above-knee amputation have demonstrated improved gait pattern and stump pressure. There is less compensation when wearing MBTs as they promote a smooth rolling action through the foot which helps to progress the weight transfer forward. Consult with your physiotherapist or orthotics if you would like to use MBTs.
As with multiple sclerosis, MBTs may be used as part of active rehabilitation programme. MBTs will not alter the natural clinical progress of the disease but may well serve to assist maximal motor functioning during the disease process.
A heel raise for a true leg length discrepancy (usually due to a congential abnormality or due to a fracture of the femur or tibia) of one centimetre or greater should be worn with MBTs (most commonly this is due to a congenital abnormality or following a fracture to either the femur or tibia). If the discrepancy is less than one centimetre then normally a raise is not necessary. This raise should be built into the shoe by the MBT customisation centre as a full-length raise is needed to maintain the biomechanical action of the MBT sole.
If the leg length abnormality is due to muscle shortening or joint dysfunction caused by tendon or ligament dysfunction, the individual should consult a musculo-skeletal specialist as the problem may be amenable to remedial treatment and heel raises may not be required.
The burning sensation experienced by certain individuals is due to increased blood flow to the intrinsic foot musculature. This should settle after a few weeks. In certain individuals, it may persist for longer and can be an indication of impaired vascular, possibly due to conditions such as arteriosclerosis or diabetes. If it persists, the individual is advised to contact his/her family physician to organise baseline investigations.
Because the MBT technology makes the foot muscles more active than in conventional flat shoes, the muscles in the feet begin to work harder in rolling through the foot with each stride. This can lead to conditions of improved circulation and activation of the muscles in the calf and around the shin, which are mostly passive in normal walking. Sensations such as pins and needles, sweaty feet and numbness can initially occur and will subside after wearing MBTs for a period of time.
MBTs were developed as a medical device. In the past few years we have learned about the toning effects. MBTs help to tone and firm the muscles of the abdomen, buttocks, thighs and calves and increase circulation. We have a great deal of positive customer feedback regarding cellulite reduction.
Wearing MBTs activates the stretch reflex, thereby helping tone the postural muscles, increasing circulation. Wearing MBTs during aerobic exercise will help you burn more calories, thus helping you to lose weight.
Our Buying team has selected the styles that are best suited for the UK market, unfortunately we cannot stock all styles. We welcome your feedback on our product range.
Each pair should come with a DVD package that includes an instructional DVD and leaflet
We don’t use the measuring board to fit our customers anymore as this is an outdated method. It is only accurate for Sport Black, White, and Grey. As our range now has so many different styles, the best method to ensure your size is correct is a personal fitting with a trained member of staff in-store.
We have various “Destination Stores” throughout the country who stock our full range. These can be found in our “Where to Buy” link at the top of this page. If none of these are close enough to you, you can use the same section to find your nearest retailer by typing in the first half of your postcode and pressing enter. You can then call them and enquire as to which styles they hold in stock and if they do not stock the style you are looking for, they may consider placing a special order for you.
