Stress fracture reduction midsole

摘要

A shoe that reduces the likelihood of stress fractures occurring in the wearer's metatarsals. The shoe includes a midsole made of (i) a stress modulation layer that is made of material of relatively high duromoeter in the region of the first, fourth and fifth metatarsal, and a material of medium durmoeter in the region of the second and third durometer, and (ii) a stress moderation layer made mostly of a material of relatively low durometer.
