I bought these shoes exclusively for gym use, as I lift weights and use gym machines regularly during the week.  At first these shoes were rather comfortable and didn't have a problem, but after a couple of weeks they just seemed to be too tight and uncomfortable.  I would agree that these shoes most likely require a half size larger as they are rather small.

It's too bad, because I have worn several New Balance shoes and have been satisfied with them.  I really like the look and color of these shoes too (the Blue).  Just haven't been able to find a comfortable minimal shoe.
