I've had my game changers for about a monthor 2 now, I can feel the difference. I have normal size arches, if you want to know what kind you have, go to wal mart or look up the nearest dr schools kiosk where you stand on a thing to be fitted for their insoles, it take a couple minutes and at the end it tells you what kind of arch you have.
When ever i put on a pair of shoes now without the game changers in them, i can tel that the arch support isnt there. It feels nice and solid under my foot. Didnt fit in all my shoes though, a couple were way to tight but they fit great in Huf Dylans, Lakai Guy mars and cons weapons. I had less luck in the huf liberty and sutter.
I always switch the insoles to my game changers now when ever i change shoes. I guess they do help, once you feel the arch support, and then un feel, there's gotta be something good happening i would think. As far as the impact protection, It's good, my feet feel fine after skating, but i dont jump off anything over 2 feet.
I want a couple more of them honestly.
