The New JumpSoles Speed & Jump Training System v 5.0

They really help with balance, but you can easily trip if you’re not careful. They are definitely helping to sculpt my calves!

My shoe size is 9.5, so I bought a medium in the JumpSoles which are suppose to fit shoe sizes 8-10. They run way too small, I tried them with multiple shoes, the ones in the picture were the only ones that fit. And they barely fit, the Velcro straps are barely hanging on. Also, I don't want to wear them with these shoes, as they are my daily indoor basketball shoes. I may have to return these & buy a size Large.Edited: I bought a size up, & they're still too small. They do not get wider, only the length increases a bit & the straps get a big longer when you go up a size. Very unfortunate, basically none of my shoes fit so I will be returning them & buying the strength training shoes instead.

Use these and do 300 steps minimum on a stair climber and you will dunk. I was dunking at 6ft 250. I lost one of the heel straps and don’t wanna buy a new pair.

The shoes do fit my son but the only that I have a problem with this company is that the disk that comes with it doesn’t work so I’ve had to view other videos for my son to perform.

These run small. I wear 13 and bought the Large which say 11-14. My shoes are very snug which is ok for me but anyone wearing 14 should get extra large. My other complaint is the heel strap is very short. If you’re advertising this for 11-14 yet the heel strap is too short for my 13. I paid $182. Total after tax &shipping These should WORK AS ADVERTISED.I know these work well to improve calve strength and vertical because I know a bunch of people that used them and that’s why I bought them. But I expected they FIT AS ADVERTISED.

Very professional ! Excellent !

I bought these for my 12-year old son instead of strength shoes, as he can use these as his feet grow. He absolutely loves them. Wears them around the house, jumps rope in them, and would wear them to school if I let him! He feels his calves have gotten much stronger. Great overall purchase!

The product looks sturdy and it does add a certain level of difficulty to any exercise. It will be interesting to see if there's any results in 60 days or so.
