Abstract

The invention relates to the technical field of sole manufacturing, and discloses a buffering anti-strain sole and a manufacturing process thereof. The upper surface of a sole bottom surface is provided with a sole surface, the rear end of the sole bottom surface is provided with a sole heel, the bottom of the sole bottom surface is provided with sole lines, and the upper surface of the sole surface is provided with a buffer layer; the buffer layer comprises a front air cushion layer arranged on the upper surface of the sole surface, the lower portion of the front air cushion layer is communicated with a middle air cushion layer, the lower portion of the middle air cushion layer is communicated with a rear air cushion layer, and protruding massage points are arranged on the upper surfaces of the front air cushion layer, the middle air cushion layer and the rear air cushion layer; a stress part is arranged on the side edge of the surface of the sole. The front air cushion layer, the middle air cushion layer and the rear air cushion layer are in special vacuum design, the front air cushion layer, the middle air cushion layer and the rear air cushion layer are all communicated, free ventilation can be achieved, strain to joints of the human body during walking can be effectively reduced, and the protruding massage points have the acupuncture point squeezing, stimulating and massaging functions on the human body.

Description

technical field [0001] The invention relates to the technical field of shoe sole manufacturing, in particular to a cushioning anti-strain shoe sole and a manufacturing process thereof. Background technique [0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole and heel. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, good elasticity, easy to fit the shape of the foot, and not easy to change shape after being shaped. Insulation, easy to absorb moisture, etc., and at the same time, it must cooperate with the midsole, which has a braking effect when walking and changing feet so that it will not slip and is easy to stop. There are many types of sole materials, which can be divided into natural base materials and ...
