Middle distance runners are tough, no doubt about that. So we made the Hyperion Elite MD to help you get the most out of yourself in every race. Designed for 800m - 1,500m track races, these ultralight spikes deliver just-right cushioning plus an ultralight carbon fiber propulsion plate to help you power forward. The 6-pin spike design provides reliable traction while helping you stay aggressively up on your toes to pass runners and pull away to the finish line.
