What is the right size of MBTs?
Closed models are worn tight on the heel, snug on the instep, and comfortable on the toe. Sandals are worn with the heel as far back as possible, the toes reaching the very front end of the sandal, and the straps tight, but comfortable. The footbed should mirror the foot as closely as possible. Unlike conventional footwear that causes the foot to slide forward with each step, the rolling motion of MBTs drives the heel back.
