I am usually skeptical about most weird inventions and gadgets, but the Strength Training Shoe is amazing. I am about 5 '9 and white. Since I started using the shoes I immediately noticed my calf size increasing. I trained with them about an hour a day doing simple stuff like running, jumping, and even, shooting a basketball. Basically as long as you wear these shoes you will continue to increase your vertical.
Before I had these shoes I could barely jump and touch the net, but now I can dunk a volleyball (and can easily touch the rim) thanks to the shoes.
If your serious about improving your athletic ability, quickness, vertical leap, or just your calves, then these shoes are for you.
I bought mine off amazon and have never looked back!
