Supporting structure for foldable bottomless rainproof shoe cover

Abstract

The present invention relates to a supporting element of a foldable bottomless rainproof shoe cover assembly. The shoe cover assembly includes a front sheet, a rear sheet, a supporting element, and combining pieces. The supporting element is continuously provided on a peripheral edge of the front sheet to substantially form an L-shaped loop. The rear sheet is provided with a notch to be combined with the front sheet. The combining pieces are provided on front and rear edges of the rear sheet respectively. Four bending points of the supporting element are provided with a wrapping portion respectively. By this arrangement, the supporting element helps the shoe cover assembly to cover the shoe of a user and makes the shoe cover assembly to be folded easily for better storage.
