US Patent 11369161 Slip resistant expansion overshoe

A slip resistant overshoe allowing expansion between a toe section and a heel section to allow a variety of shoe sizes and types to be inserted. The overshoe is formed from a sole having a flexible shank connected to an upper member. The upper member includes a front section and a rear section with opposing side sections therebetween. Each of the opposing side sections and flexible shank includes a corrugated shape to allow expansion of a distance between the front and rear section; a flatter surface resulting in greater slip resistance. Channels formed along a toe section and heel section expand and contract to expel debris providing an anti-clog function to maintain material slip resistance of the overshoe.
