MBT stands for Masai Barefoot Technology. The company that makes MBT shoes (also known as the anti-shoe) is Swiss Masai. The uniquely-designed, multi-layered, cured sole is designed to simulate walking in sand (similar to the natural walking environment of the Masai in Kenya). This creates a natural, uneven walking surface and forces the body to use all the major and stabilsing muscle groups, thus training the whole body to move correctly.
