“Handcuff” Universal-Fit Ankle Rings, new improved rotation easy-slide end puck, and more! You’ve seen the problem…smaller students battle with ankle rings that fall off their heel before they even start; older students have to take off their tennis shoe just to get the ankle ring on. Both problems take away from usable exercise during the class period. The new Ball Hop II™ has a smaller dia. open-and-close “handcuff” ring that won’t slip off small shoe sizes, and avoids the need to take larger shoes off. Just press down on the release tab to open the ring, and ”click-lock” it closed. Sold in a set of 6 COLORZ.
