In 2001 NSI introduced the first heel straps that utilized inner tubes. Although this was a great concept, installation was a hassle and the straps had a tendency to slip off unless they were uncomfortably tight. To solve these problems, NSI & Hein have designed a patent pending attachment method that wraps around the footstrap instead of being sandwiched under it. The new attachment system improves retention by moving the direction of the tension upward, so the strap won't slip off. They are easy to install, adjust and remove without taking the footstraps off, and can be stowed on top of the strap when not in use. Combine all this with an extremely comfortable soft foam and neoprene.
