  • Flexible sheet materials suitable for use in the present invention include but are not limited to microporous films, polyester and polyolefins.
  • the flexible sheet material comprises polypropylene or polyethylene.
  • Polyethylene is preferred, for example TYVEK®, available from E. I. du Pont de Nemours and Co., Wilmington, Del.
  • Flexible sheet materials suitable for use in the present invention can be produced by methods known in the art such as hydroentangling, carded thermal bonding, spunbonding, or meltblowing.
  • the invention as depicted in FIG. 1 is a disposable footwear cover 10 having an inner surface, an outer surface, a lower leg region 35 , an ankle region 30 , a metatarsal region 20 , a toe region 25 , and a sole region 28 .
  • the disposable footwear cover 10 includes elastic material to gather excess sheet material and provide a snug and improved fit.
  • elastic gather refers to elastic bands, threads or the like that are attached to the flexible sheet material.
  • elastic gathers 50 , 60 and 70 are typically located respectively on the inner or outer surface of the footwear cover in each of the lower leg region 35 which encompasses the region about 2 cm below the knee to about 2 cm above the ankle, the ankle region 30 which encompasses the region about 2 cm above the ankle to about 2 cm below the ankle, and the metatarsal region 20 which encompasses the region of about the balls of the feet to the heel.
  • the elastic gather 50 located in the lower leg region is typically placed surrounding the boot cover opening.
  • the elastic gathers are typically less than about 2 cm wide.
  • the elastic gathers are less than about 1 cm wide.
  • the elastic gather is an elastic thread.
  • the elastic gathers are typically made from materials such as spandex, natural rubber, polyurethanes, and combinations thereof.
  • the elastic gathers can be attached to or incorporated into the flexible sheet material of the footwear cover.
  • Typical means for the attachment or incorporation of the elastic gathers include stitch bonding, adhesives, sewing and tunnelization (enclosing an elastic in a strip of like flexible sheet material and sewing the strip to the footwear).
  • the elastic gather of the lower leg region 50 typically encircles at least a portion of the leg of the wearer and can completely encircle the wearer's leg.
  • the elastic gather of the lower leg region 50 can extend around all or a fraction of the circumference of the lower leg region.
  • the elastic gather of the lower leg region 50 preferably encircles only a portion of the wearer's leg to allow for ease of donning. More preferably, the elastic gather of the lower leg region 50 encircles a portion of the back of the wearer's leg. Most preferably, the elastic gather of the lower leg region 50 encircles about 30 to 80 percent of the circumference of the wearer's leg at the area of contact.
  • the elastic gather of the ankle region 60 is typically placed as to gather excess material of the footwear cover and provide a snug fit.
  • the elastic gather of the ankle region 60 can extend around all or a portion of the circumference of the ankle region 30 .
  • the elastic gather of the ankle region 60 extends around 25 to 80 percent of the circumference of the ankle region 30 of the footwear cover.
  • the elastic gather of the ankle region 60 additionally extends around the back of the ankle.
  • the elastic gather of the ankle region 60 extends around 25 to 60 percent of the circumference of the ankle region 30 of the footwear cover including the back of the ankle.
  • the elastic gather of the metatarsal region 70 is typically placed as to gather excess material of the footwear cover to reduce the possibility of tripping and provide a snug fit.
  • the elastic gather of the metatarsal region 70 typically extends across the metatarsal region 20 from about one edge the sole to about the opposite edge of the sole.
