I am a long time barricade user, but I am tired of tearing through each pair in a month. I am looking at the Nike Air CourtBallistec 2.1, this shoe looks very nice, is affordable, and seems to be on a line of very good tennis shoes (the ballistec series). My question is how does this shoe run in sizing? I am wearing a 9.5 with the barricade, does Nike run bigger, smaller, the same...? Also, how does this shoe compare to the 2.3's, is there much of a difference, and if so, what would that difference be? Any feedback would be appreciated guys, thanks!
