Jumpsoles are the world's most popular tool for increasing your vertical jump. Jumpsoles are plyometric platforms that attach to your shoes. Jumpsoles focus your body weight onto your calves and train you to spring off the balls of your feet like a powerful cat.By doing the special plyometric exercises in the video you develop fast twitch muscle fibers in your legs for explosive leaping improvement.

Ie; You wear a 10.5 shoe? You should order Large Jumpsoles, not Medium. I'm week 5 of the Jumpsoles program and i can already throw it down with 2 hands!!!!! (that's from not being able to dunk at all b4) and i can do it with authority!! Jumpsoles are fantastic, the order got here quick. My son is in his 5th week of workouts and I can already see significant improvements in his jumping ability and explosiveness. Would recommend them to any athlete that wants to take their game to the next level. My son has been using the jumpsoles for the last three years and has been the National AAU high jump champ in his age group the last two years.
