I have been wearing these shoes for the past 3 years, but I hate the 6 neon colors that come on the shoe so I decided to order a pair of the ID's and it is a vastly inferior product despite the extra cost, there is all sorts of exposed stiching that caused multiple blisters on my feet form one five mile run, and the product just feels cheaper. Just wanted to put a warning out there, I guess I will stick with the regular frees despite the ugly colors.
