The ToughBuilt GelFit non-marring gel and foam knee pads are exceptionally comfortable and ergonomically shaped to embrace the knee and upper shin. These work knee pads can be used with or without non-marring SnapShells which can easily snap off and interchange with other SnapShells so you can have the perfect knee pads for every job. The perfect companion for tradespeople, these Toughbuilt gel knee pads are made from pliable rubber that prevents scratching and marring and conforms to the floor, maximising pressure distribution for all-day comfort, while the high side walls greatly reduce any twisting of the knees. Made from abrasion-resistant 1680D fabric and featuring EVA elastic leg straps that comfortably hold their place without cutting off circulation or binding behind the knee, these ergonomic work site knee pads are recommended for delicate surfaces, hard wood, marble and tile.
