Leather clog with leather insoles, a built-in arch support (removable to allow for insertion of custom orthotics,) the foot bed is anatomically correct to form the natural shape of your foot, the 1 1/2" rocker outsole is engineered to roll naturally to reduce heel pressure and encourage proper posture and normal gait; the flat bottom maximizes contact with the floor to increase stability, and extra depth gives you a roomier fit so you can wiggle your toes.
