Patent ID: 8474153

Claim:
A shoe cover comprising: a sole made of a flexible material having; at least two rigid bands made of rigid material, each having a first portion disposed on a ground-contacting side of the sole and arranged in spaced relation to each other on opposite sides of a longitudinal axis of the sole, thereby rigidifying the sole; at least one elastic band made of said flexible material, spanning longitudinally between said at least two first portions from a front end to a rear end of the sole, thereby enabling the sole to be laterally flexible to adapt to a shoe over which the shoe cover fits; and wherein at least one of the rigid bands comprises: a second portion attached to the first portion and extending upward from the first portion along a side wall of the shoe cover, the attached first and second portions thereby producing at least one rigid L-shaped element; and a fulcrum contacting the ground and having a fulcrum axis formed where the first and second portions are attached, the first portion being angled with respect to a horizontal plane so as to have a raised inner part raised from the ground toward a center area of the sole when no downward pressure is exerted, and enabling the second portion to rotate about the fulcrum axis and toward a side wall of the shoe inserted within the shoe cover to an inward position when a downward pressure is exerted on the raised inner part of the first portion, thereby clamping the shoe.
