Air-pressure shoe pad

Abstract

An air-pressure shoe pad comprises a pad body arranged on a tread surface inside the shoe and a plurality of hollow columns arranged on the lower surface of the pad body at intervals. A first air bag is formed by the tread surface, the lower surface of the pad body and an inner wall of each column. When the columns are deformed under the external force, the enclosing walls of each column can deform by extending outwards so as to mutually contact the outer walls of adjacent columns and form a second air bag together with the tread surface and the lower surface of the pad body. Through the formed first and second air bags, the air-pressure shoe pad has high elasticity and can absorb vibration and each column has enough extending space, therefore efficiently solving the damaging problem caused by deformation under the external force and prolonging the service life.

Description

technical field

[0001] The invention relates to an insole, in particular to an air pressure insole which has high elasticity, is easy to manufacture, and can instantly form an air bag under pressure. Background technique

[0002] Shoes are an indispensable necessity in daily life. Due to different functions and appearances, there are various types on the market. However, no matter how the appearance of the shoes changes, they are comfortable to wear and provide sufficient support for the feet. image 3 It is a plan view illustrating another existing decompression insole device.

[0003] The improved structure 1" includes an insole 11 and a buffer guard 12 detachably arranged on the insole 11. Also refer to figure 1 and figure 2 , the insole 11 has a round hole 111 at the place where a heel (not shown) steps on, and the buffer guard 12 is detachably clamped in the round hole 111, and the buffer guard 12 includes an outer air bag 121 , and a plurality of inner airbags 122 ...
