A shoe cover has an upper and a sole connected to the upper. The upper includes at least one, self-supporting and resilient shoe admission portion connected to the sole. The shoe admission portion has an inwardly inclined lead-in surface extending toward the sole, and an overhang surface extending from the lead-in surface toward the sole portion. The overhang surface is adapted to form an undercut area so that a shoe to be held to the shoe cover first engages and slides along the inclined lead-in surface to resiliently expand the admission portion outwardly without being crushed, and then slides into engagement with the overhang surface to enter the undercut area. A length adjusting mechanism may be provided for adjusting the length of the sole.
