  • Patent number: 5787607
    Abstract: A shoe cover for being worn over the shoes consists of a cover foil adapted to protect the shoe and at least a part of the calf of a person and a reinforcing foil adapted to reinforce at least the sole portion of the cover foil. The cover foil is made of a first soft or plasticized polymer, and the reinforcing foil is made of a second soft or plasticized polymer. Besides the sole portion, the cover foil consists of a shaft portion. The sole portion of the cover foil is reinforced by the reinforcing foil by welding them together by means of a plurality of punctual welding points. Those welding points form a plurality of punctual recesses in the reinforcing foil, which recesses cause a sucker effect, such that a high adhesion between the shoe cover and the ground results. At the shaft portion, the cover foil is provided with a strap or a tape which allows to tighten the shoe cover at the foot or calf of a person.
