Sports and Therapeutic Taping - RockTape Extra Sticky Bulk Roll, 2" x 105', Black, 1 Roll : RockTape is a solid kinesiology tape that is made even stickier to meet the demands of top athletes and austere environments. Use it to treat sports and non-sports injuries, including shin splints, plantar fasciitis, runner's knee and back pain. It boosts recovery by microscopically lifting the skin away from the muscle and fascia below, which decompresses the area and promotes blood flow. Using RockTape also increases awareness of your body position to help you maintain proper posture and form. With the extra stickiness of the adhesive, the tape will last 2 to 10 days after being applied. It is extremely water resistant and is made of 97% cotton and 3% nylon. The 180% stretch allows for full range of motion, so you don't have to worry about the tape restricting your movement. RockTape is both latex and zinc free. This single extra bulk sticky roll is black in color and measures 2 inches wide and 105 feet long.
