In contrast to Easytone shoes, the Runtones feature 5 small air filled pods in the heel, and one in the forefoot, with the surface area increased than that of the Easytones to maximise grip. Three narrow rubber strips on the forefoot give much better traction for fast running, and allows the movement of air within the pods to be better controlled for added stability. Reebok Runtone shoes also feature DMX shear cushioning to better absorb the strike force generated in when the heel is grounded for a highly comfortable ride, with the foot propelled forward from the heel to the toes in a smooth fluid motion.
This will allow you to open up the stride length in a natural way and it will also allow for more power when your foot hits the ground. You'll notice that a lot of athletes break down at the end of their races. The reason why is because their leg cycle is out of sync. Just remember to keep a steady rhythm while sprinting and you should continue to keep your ankle stepping over the opposite knee.
