Thin, lightweight footwear made of a polyethylene material that is composed of a top part and a sole part that are sewn together such that when fitted properly to the wearer's foot the footwear encompasses the foot and extends to the level of the ankle. The top part is porous allowing the ingress and egress of soap and water. The sole has slip resistance properties due to the material from which it is made and the texture of its outer surface. The finished product can be folded and compressed for storage, then later unfolded and worn without the folding adversely affecting its intended function of providing a barrier between the wearer's feet and the tub or shower floor on which the wearer stands while the wearer showers.
