First off, you definitely want to follow the sizing recommendation and go a half size up from your non-
Nike shoe size. I am an 8½ in all other
flats and bought a 9 in these. Secondly, you should know that these shoes are not for people who want a lot of support in their footwear. These shoes are super minimal and great for people who are doing a lot of lifting or plyometrics and like the feel of a barefoot workout. I took these for a spin today, and while they were not totally comfortable out of the box, I think that was largely due to my not being used to such minimal support. I usually wear
Nike free runners and these have significantly less cushion than those. After wearing them for a full training session, I can definitely say that they are worth a try for anyone who is drawn to things like five finger or other minimal training shoes but want a different look.
