I'm sorry...but 315 isn't "big weight" unless you are well WELL under 100 lbs, playing pop league ball, or are a small woman. At age 16 I full OLY squatted 405 x 8 in a pair of Wal-Mart knee wraps and a Wal-Mart "belt". I wasn't barefoot nor was I wearing a pair of Nike Shox.
Before you want to down the "doubters"...maybe you should take half a second and realize what some of us "doubters" have accomplished.
WHY would you want Squat shoes with big arch support? You think that the ONLY reason one would wear "squat shoes" is "arch support"? It is clear that you do not have a clue of the concept as to why Chucks are a superior squat shoe for most. Depending on stance and preference...and OLY shoe could be 1st (I have and use both).
