Using them is simple: If you have carpet, face the hard side of the sliders down. If you have hard floors, soft side down. Then slide them around—under your hands or the balls of your feet, depending on the move—in mountain climbers, skater squats, and plank modifications. Hard side: polypropylene; Soft side: EVA foam, neoprene mesh fabric 7″ x 7″.
