Hey guys, i just got a pair of fks and im not sure if its a definite problem, but the heel piece's have some wierd play going on whenever you move them. Like you can push them forward and backward say 1-5 mm when their clicked in or out,and the screw pieces are fully screwed in if you know what i mean. If anybody knows what the deal is here or if its just nothin can you guys let me know. Thanks +K.
