About MBT: SINCE 1996 Karl Müller, a mechanical engineer who graduated from the Swiss Federal Institute of Technology Zurich, suffered from severe knee and back pain. However, he noticed that his knee and back pain were reduced after walking barefoot on soft soil. Then, he developed an innovative sole (shoe sole) that reproduces the unstable ground like soil. It has become possible to reproduce "natural instability" even on hard and flat asphalt. Masai Barefoot Technology The distinctive curved sole is a conditioning shoe with the only function in the world that reproduces the same exercise as the Masai people walking barefoot in nature. *Individual results may vary.
