ANTI-SLIP SOLE WITH STEEL STUDS FOR OUTDOOR USE AND ICE SURFACES Russian patent published in 2023 - IPC A43B13/00 

FIELD: shoes materials.

SUBSTANCE: present invention describes an anti-slip sole with steel studs for outdoor use and on icy surfaces. The device structurally comprises a studded hoof frame, a concave-convex serrated sole, a studded heel frame, and a one-piece composite sole. According to the present invention, due to the combination of a concave-convex serrated sole and a one-piece composite sole, as well as thanks to the hoof-shaped frame with studs and heel frame with spikes, the manufacturing of the sole of the present invention is possible by opening the mould and removing from the mould various sole materials that have hardness and elasticity. Short conical studs are inserted into a concave-convex serrated sole and a one-piece composite sole to form a moulded sole with a variety of rough surfaces suitable for uneven ground and smooth slopes. The present invention achieves the effect of flexible extension and return of the studs, thereby improving the slip resistance of the steel studded anti-skid sole on the street and on icy surfaces, while not limiting the invention in terms of applications and moulding materials. According to the functionality of Hooke's law connecting nodes, the hoof-shaped frame formed by the anti-skid structure and steel studs imitates the hoof of an animal to realize the anti-skid function.

EFFECT: wrapped and combined sole improves the anti-slip effect and promotes walking comfort.
