Masai Barefoot Technology ( MBT Shoes ) is not just a shoe in the ordinary sense. It is a revolutionary fitness aid from Swiss Masai. MBT shoes will not only change the way you use your muscles, but will improve the use of your joints and spine. The MBT shoe has been highlighted for its ability to cushion your feet while challenging your muscles. Clinical studies suggest that regular use improves balance, posture and circulation. MBT Shoes re-establish the natural conditions for standing and walking. MBT Shoes lets our flat everyday surface become naturally uneven. You walk as if you were walking in sand, as MBT shoes neither support, guide nor absorb shock; rather it stretches, increases power and coordination of the muscle apparatus.
