Vertical Jump Training Shoes?

I think we all have heard of vertical jump platform training shoes, but these are completely different. These shoes are called APL Athletic Propulsion Labs Shoes. These are basically basketball shoes that you could wear in a game or practice. Yes, these shoes do look a lot like your everyday basketball shoe, but oh they are not. These shoes actually increase your vertical while your playing. No training and no more hours of hard work. Some people might be able to touch the rim or even grab it, but may not be able to dunk. Well than these shoes would be perfect for you. They supposedly add 4 inches to your vertical INSTANTLY! And if your a really good athlete than you could add even more anywhere around 8 inches to your vertical. Now doesn't these shoes sound amazing. Yes, but do they work? Well I did some research and came to find out they these shoes actually kind of work. It turns out that these shoes work better if you are a two legged jumper, but they still work if your a one legged jumper. Should you buy them? Well that is kind of a hard question, because they work alright, but they aren't really worth their price. These vertical jump shows cost $300 and I don't know about you, but for shoes that's not a good price.
