Ergonomic footwear

Abstract

An ergonomic footwear at least includes an outsole having a top surface including a datum plane and at least one contacting portion such configured that a difference in elevation is formed between the contacting portion and the datum plane, wherein the contacting portion is located at a place to which a force is applied by a treading human foot sole of a wearer. Accordingly, such structure can prevent the wearer's sole from sliding with respect to the outsole, thereby facilitating stable treading of the wearer's sole and further enhancing the wearer's walking smoothness.
