BOOTIES AND FOOTWEAR ASSEMBLIES COMPRISING SEAMLESS EXTENSIBLE FILM, AND METHODS THEREFOR |
摘要 |
Waterproof, breathable socks, booties, shoe inserts, and footwear assemblies containing the shoe inserts are provided. The booties and shoe inserts may include a laminate comprising a seamless extensible film, such as a polyurethane film, and at least one textile. The bootie is suitable for a range of sizes and shoe shapes. The bootie may shrink to fit, or, alternatively, be stretched to fit, an asymmetrical last having a desired size to form a shoe insert. A bootie having a seamless extensible film eliminates the need to have multiple sizes of shoe inserts correlating to particular shoe sizes. In embodiments where the polyurethane film is seamless and continuous, the shoe insert eliminates the need for a waterproof seam tape, which is conventionally used to make shoe inserts waterproof. Methods of forming the socks, booties, and shoe inserts are also provided. |
