Using the NANO® X Foot Roller is easy. Just place it on the floor and roll your foot or forearm back and forth on it. You can adjust the pressure by how hard you press down. For best results, use it for a few minutes each day. When using, don't apply too much pressure at once, especially if you're new to it. If you feel any sharp pain, stop using it. After each use, wipe the roller with a clean, dry cloth to keep it clean. Store it in a cool, dry place away from direct sunlight to maintain its foam quality.
