Sport shoe and sole thereof

Abstract

The invention discloses a sport shoe and a sole thereof. The sport shoe sole comprises a first cushioning layer, a second cushioning layer and a third cushioning layer which are sequentially and fixedly overlapped from top to bottom, the second cushioning layer is vertically provided with a plurality of columnar through holes, the through holes are provided with annular grooves along the inner circumferential surfaces of the through holes, the annular grooves and the through holes are coaxial, the radiuses of the annular grooves are larger than those of the through holes, and air with one atmospheric pressure is prefilled into each through hole. The through holes are sealed to form air columns after the first cushioning layer, the second cushioning layer and the third cushioning layer are fixedly connected, the elasticity of the air columns is increased by the annular groove structures on the air columns, the air columns can generate larger compression deformation when pressure is applied to the sole, two portions of each air column positioned on the upper portion and the lower portion of the corresponding annular groove can be pressed together, the cushioning performance of the sole is greatly improved, the probability of sport injury is effectively reduced, and the service lives of the air columns can be prolonged.
