These are really cute. They seem to fit true to size but are snug, and feel narrower than I'm used to in Nike or Inov-8 shoes. If I bought them again I'd go a half size bigger, or if it were available maybe one width bigger. The soles are really firm, but the shoes are still pretty lightweight. All in all seem good. Love the colors ("aqua" which is really yellow blue and pink and change colors depending on which direction you are looking at them) they match all of my workout clothes, which lets be real, that's all I was really hoping for.
