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.
