I've always worn the structure triax and love them, but have lately been feeling weird about spending $100 every few months on another pair. Mostly, because I don't have a lot of disposable income right now, and would rather use it on things i can eat... I also have close to zero idea when it comes to shoes. All i know is I overpronate pretty severely... anyone who knows shoes have any thoughts? I also have a very narrow foot...and i'm a guy, size 10.
