DETAILED DESCRIPTION

[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0021] See also Figure 1-7The utility model provides a technical solution: a low-density thermoplastic polyurethane microporous foamed casual shoe, comprising an upper 1 and a sole 2, wherein the lower end of the upper 1 is fixedly connected to the sole 2, and the inner wall of the sole 2 is provided with a ventilation mechanism 3, by controlling the size of the internal space of the hollow tube 302, the air inside the hollow tube 302 flows outward and inward, so that the ventilation of the lower end of the sole 2 is more obvious, the ventilation mechanism 3 comprises a threaded ring 301, the outer wall of the threaded ring 301 is fixedly connected to the sole 2, the inner wall of the threaded ring 301 is threadedly connected to the hollow tube 302, the inner wall of the hollow tube 302 is fixedly connected to the connecting block 303, the end of the connecting block 303 is fixedly connected to the disc 304, and the inner wall of the hollow tube 302 is provided with ventilation holes 305;

[0022] The hollow tube 302 and the sole 2 made of low-density thermoplastic polyurethane expand and contract under the pressure of footsteps, making the internal space of the hollow tube 302 smaller. The disc 305 inside the hollow tube 302 hinders the outward flow of the air hole 305, making the thrust of the air volume discharged outward from the air hole 305 more obvious. The air passes through the insole 8 and contacts the sole of the foot, thereby improving the breathability and comfort of the lower end of the sole.

[0023] See also Figure 1 , Figure 2 and Figure 5 An adjustment mechanism 4 is provided on the outer wall of the upper 1, and the strap 401 adjusts the tightness of the upper 1 through the contact between the multiple hook-surface Velcro 402 and the fleece-surface Velcro 403 on the strap 401. The adjustment mechanism 4 includes a strap 401 and a mounting pad 404. The end of the strap 401 is fixedly connected to the upper 1, the outer wall of the mounting pad 404 is fixedly connected to the upper 1, the outer wall of the strap 401 is fixedly connected to the multiple hook-surface Velcro 402, the outer walls of the multiple hook-surface Velcro 402 are adhered to the fleece-surface Velcro 403, and the outer wall of the fleece-surface Velcro 403 is fixedly connected to the mounting pad 404.

[0024] See also Figure 1 and Figure 2 The inner wall of the sole 2 is installed with micropores 5, the interior of the micropores 5 is connected to the hollow tube 302, the outer wall of the upper 1 is fixedly connected to the anti-collision plate 6, the lower end of the anti-collision plate 6 is fixedly connected to the sole 2, the inner wall of the upper 1 is fixedly connected to the tongue 7, and the surface of the sole 2 is in contact with the insole 8.

[0025] Working principle:

[0026] Use phase
