I buy a 10.5 in athletic shoes, which is one of the reasons I buy New Balance- they carry a wide selection in this size.  This shoe fits like a 10. I can still wear it (I wear 10 in every day shoes and only go up to 10.5 for running shoes) but I cannot run long distances because of it being just a bit short. I bought a different style of New Balance shoe at the same time, and they fit fine, so I think it's probably this specific style of shoe.

Even though I don't love the fit, I won't be returning them as they are still a great every day shoe. I spend a lot of time on my feet, and these are comfortable and light. The lower profile is nice- it looks more like a casual Ked or Converse style of shoe, but with the support and feel of a regular cross-trainer. I may try a wide size the next time I look at getting this shoe, to see if that makes it roomy enough to run in. But it will do for just a different purpose.
