Jump Soles - Small (Sizes 5-7)
Brand: ATHLETIC SPEED EQUIPMENT

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 manual you develop fast twitch muscle fibers in your legs for explosive leaping. Used by slam dunk contest winners and top pro & college teams, Jumpsoles are guaranteed to boost your vertical jump 5 - 10 inches!

Jumpsoles when used regularly and intelligently according to instructions maximize and distribute the workout to your calves and forefoot.
Up to 30% of your vertical jump is generated there, and those muscles are available and waiting to contribute crucial inches to your vertical jump.
If you're serious about building anything like your vertical jump, having tools is better than having no tools!
JUMPSOLES are the only platforms which attach onto your own shoe.
The almost 3 lbs of extra weight added to the outermost part of your feet make JUMPSOLES heavier than any platform shoe for a harder workout.
