I had a pair of them not long ago!!! I was going to get good at them and do a massive dunk for the TVS viewers choice dunk contest lol. They are sooooooooo hard to get good at though. It looks so easy when the guys do flips and stuff but when you put them on first you can't walk at all. I wanted to give up after like 5min lol. I could only just do smallish jumps like 20" before I sold them because I figured having 2 broken arms wouldn't be too good for my vert training. Dangerous as hell. If you fall its a long bloody way down!
