I bought the Go USA version because they looked unique and when I tried them at the store seemed to fit very well. The problem was when I actually went jogging in them. They rubbed the heel on the backside no matter which sock I tried to wear with them. I read the Academy return policy and they won't accept items that have been worn. Disappointing. I suggest simulating running in the store so you don't have the same problem. I even wore them around the house first but it was the running motion that caused the rubbing of the back heel of my foot to have blisters. Maybe I needed the smaller size but what's interesting is I usually wear a woman's 8 in a running shoe and these are a 7.5. I can't believe it would be a full size smaller than other brands I wear like Nike and Mizuno.
