Jumpsoles are platforms that attach to your shoes. Jumpsoles may help increase your vertical leap an running speed. They work on strengthening your calf muscle and Achilles tendon, by making you stay on your toes while doing Plyometric exercises. Using Jumpsoles help work muscle in the calf that can’t be worked by just doing Plyometric exercises alone. After using Jumpsoles once it is directed to remember that your legs need at least 48 hour rest to restore the muscle, before additional exercises are done.
