Prosolez is an alternative to going barefoot. Its a thin rubber, non-latex, water proof material. Prosolez was created to prevent slips and falls, and the spreading of foot fungus. You simply peel off the thin layer of paper on the top side of Prosolez and off you go! The bottom of Prosolez is a corrugated design to channel water away, like the tread of a tire. The corrugated ridges on the bottom of Prosolez granted my product as a patent design.
