I wore the shoes for almost a week. Normal everyday walking, never even got a chance to run in them. The internal lining began curling at the instep which was very uncomfortable. I would reach down and unroll it by the end of the week it was roled up about a half inch and hurting too bad to wear. The insert was removable and I suppose I will go purchase some gels. Otherwise the fit was good and received several complements on the really cool colors. Not sure if the rest of the shoe will hold up especially with running- which I plan on. They are really light however and breath very well. Since both shoes did the exact same thing, I doubt this was just a fluke. I really hate that I paid this much as usually I get Asics Nimbus or Kyano for the same price and they hold up for 2-3 years before I just buy a new pair simply so they look better.
