Ergonomic foam design embraces the natural shape of the knee and upper shin, maximizing pressure distribution for all day comfort. High side walls greatly reduce twisting off of the knee. The hard-wearing, pliable shell conforms to the ground and floor without leaving marks and scratches. EVA elastic leg straps comfortably hold their place without cutting off circulation or binding behind the knee. Rugged materials and construction make these reliable knee pads withstand the most rigorous working conditions.
