Ski-Glide technology is a special, polymer-based film encased to the base of the protective feet. This allows the legs to glide smoothly on hard surfaces whilst protecting the floor. Its ultra thin and translucent design means it’s virtually invisible, yet practically priceless. These unique polymer discs are included in every box giving you the freedom to choose when to add them to the feet. No other seller provides both the feet and the polymer film, SkiSki LegsTM offers you both in every model, every time.
