Abstract
A shoe or foot covering with slip-resistant properties is disclosed. The shoe cover includes a slip-resistant material that is applied to the bottom portion of the shoe cover. The slip-resistant material may be a substantially amorphous atactic olefin polymer.
Claims35
A foot covering comprising:
- a body shaped to surround a foot of a wearer, the body defining a bottom portion having an outside surface designed to contact the ground when the foot covering is being worn;
- and
- a slip-resistant material applied to the outside surface of the body, the slip-resistant material comprising a substantially amorphous atactic olefin polymer.
A shoe cover comprising:
- a hollow body defining an opening for receiving a foot or a shoe, the hollow body being made from a nonwoven material, the body defining a bottom portion having an outside surface designed to contact the ground when the shoe cover is being worn;
- and
- a slip-resistant material applied to the outside surface of the bottom portion, the slip-resistant material comprising a substantially amorphous atactic olefin polymer.
A foot covering comprising:
- a body shaped to surround a foot of a wearer, the body defining a bottom portion having an outside surface designed to contact the ground when the foot covering is being worn;
- and
- a slip-resistant material applied to the outside surface of the bottom portion, the slip-resistant material comprising a substantially amorphous atactic olefin polymer, the polymer having a density of from about 0.8 grams per cubic centimeter to about 0.95 grams per cubic centimeter and having a polydispersity index of from about 4 to about 9.
A foot covering comprising:
- a body shaped to surround a foot of a wearer, the body defining a bottom portion having an outside surface designed to contact the ground when the foot covering is being worn;
- and
- a slip-resistant material applied to the outside surface of the bottom portion, the slip-resistant material comprising a copolymer of propylene and a terminally unsaturated olefin.
A foot covering comprising:
- a body shaped to surround a foot of a wearer, the body defining a bottom portion having an outside surface designed to contact the ground when the foot covering is being worn;
- and
- a slip-resistant material applied to the outside surface of the bottom portion, the slip-resistant material comprising a terpolymer of propylene, ethylene, and 1-butene.
A method of imparting slip-resistant properties to a foot covering, comprising:
- providing a foot covering having a body shaped to surround a foot of a wearer, the body defining a bottom portion having an outside surface designed to contact the ground when the foot covering is being worn;
- and
- applying a slip-resistant material to the outside surface of the body, the slip-resistant material comprising a substantially amorphous atactic olefin polymer.
A method of making a slip-resistant shoe cover, comprising:
- providing a body shaped to surround a foot of a wearer, the body defining a bottom portion having an outside surface designed to contact the ground when the shoe cover is being worn;
- and
- applying a slip-resistant material to the outside surface of the bottom portion, the slip-resistant material comprising a copolymer of propylene and a terminally unsaturated olefin.
A method of making a slip-resistant shoe cover, comprising:
- providing a body shaped to surround a shoe or a foot, the body defining a bottom portion having an outside surface designed to contact the ground when the shoe cover is being worn;
- and
- applying a slip-resistant material to the outside surface of the bottom portion, the slip-resistant material comprising a substantially amorphous atactic olefin copolymer of ethylene and propylene, the polymer having a density of from about 0.8 grams per cubic centimeter to about 0.95 grams per cubic centimeter and having a polydispersity index of from about 4 to about 9.
