Designed by a woman physician with 20+ years experience studying human movement and forces, OESH is a truly evidence-based footwear. The OESH sole is uniquely designed to compress and release in tune with when the forces from the ground are at their peak. OESH is designed to work for everyone no matter what "foot type". OESH is a remarkable breakthrough requiring remarkable engineering -- carbon fiber cantilevers running the length of the sole. Unlike foam in typical shoes which breaks down quickly, the carbon fiber sole performs consistently throughout the life of the shoe. With its styled leather/mesh upper, this Limited Edition OESH Classic is designed so that you can wear them for as much of the day as possible.
