Dirt Inspiration and Information
Even today in many parts of the world, it's not unusual to see population segments, such as the Masai tribes of East Africa, without footwear. It was Swiss engineer Karl Muller who studied the nomadic Masai and found that while they were constantly on their feet traversing uneven, rugged terrain, they didn't have the neck and back problems of most Europeans and Americans.
Muller studied the biomechanics of the Masai and found that they utilize muscles and bones of the foot to correct their gait over Africa's soft, natural surfaces. The key discovery for Muller: active stabilization versus passive support.
Seeking to duplicate barefoot walking, MBT designers developed a patented sole structure that included a cushy wedge (the sensor) sitting between the midsole and the outsole to mimic a shoeless stroll on the beach. This unstable pseudo-sand-walking activated lazy muscle groups that rushed in to aid balance. The negative heel angle of an MBT shoe - evident at first sight - aligned the bones of the ankle, knee, and hip as it guided the foot into the step.
But why not just go barefoot a la South African Olympian Zola Budd Pieterse? Yes, the idea is unconventional, but so are MBTs. "I think people have their footwear because it reflects on their lifestyle," says Alois Badegruber, head of product marketing for MBT, "but their shoes also need to protect their feet. MBT gives people the opportunity to protect their whole body."
MBT works because of the instability it creates, but as a model for shoe technology, it's as stable as ever: The company now boasts more than 1 million in sales.
