High-elasticity sports insole not prone to deformation

A high-elasticity sports insole not prone to deformation structurally comprises a body, an elastic positioning ring is arranged on the outer ring of the body, a sole positioning groove is formed in the top face of the body, a plurality of deformation grooves are formed in the bottom face of the body at intervals, strip-shaped transmission grooves are vertically formed in the tops of the deformation grooves, and buffer air cushions are horizontally arranged in the strip-shaped transmission grooves. The upper end face and the lower end face of the buffering air cushion are each provided with a pulling action groove, a strip-shaped air cavity is vertically formed in the buffering air cushion, the transversely-arranged buffering air cushion is adopted, in the moving process, along with compression of the insole body, the deformation grooves deform and expand outwards, the strip-shaped transmission grooves are driven to be opened, and the buffering air cushion located in the strip-shaped transmission grooves is ho
