my grandson claims that these have added 6 inches to his vertical. Excellent product that does just what it claims to do

Great shoes!
These training shoes are much better made and of higher quality than I would've thought. I redid the laces and got a better fit for my feet, and the shoes fit extremely well. I have a wide enough foot (11E), so to fit right out of the box is a pleasant surprise. The platforms are stable and sturdy, not giving a bit, putting the overload directly where it should be, on your calves. For the price, I'd absolutely get them again. Well done!

They help
These shoes were recommended to me as rehab for helping me stretch more than strengthen. At first, I thought they were a gimmick. But I trusted the person that recommended them. Others may think they look odd when you wear them, but they have helped me. I'm glad I got them.

Good quality shoe
Been using these for my 14 year old kid. I can already see his calves getting bigger and the other day he was running in front of me and he was kind of bouncing as he was running which is a good sign these are working. They make you super explosive. I used these 20 years ago in college and had the highest vert among them d linemen. Also had the fastest pro agility.

No instructions how they, to work.
I have walked in them, ran in place for a few. To calf build at home ? Must play science officer, play xtra safe, give them a fair time of play.

Jump out the building with these
I used this when I was in high school and dunked my first time at 5'6 and i grew 2 more inches these made all the difference. You need to be committed and you will increase your vertical.
