My son is a sprinter, long jumper, and triple jumper. With triple jump, he needed something more stable for the 2nd and 3rd jumps. These have been the solution, and have also helped his long jump plant/launch. They don’t fit as snug around the heel as his traditional sprint spikes, but he likes them. The strap is an added bonus because he can easily loosen the shoes in between jumps to help with circulation.
