Well I found a local store yesterday and tried them on and bought them. Worked on lowering the catch position in the snatch, and overhead squats. After working out, went and grabbed a bite to eat, took a shower and sat in them for maybe 2 hours. It's hard to tell how sore I would have been without wearing them for that length of time, but I guess they did their job cause my legs aren't terribly sore.
I will say they are s beast to get on. I got the size 4 and I did try them on. Also they do not come up as high as I thought they would. I asked the guy who has a pair at the store and was shorter than I am and he said that they are more like hippsters and shouldn't come up like underwear.
