Cory probably has the best advice. I have the 510 spires which are very similar to these. I ordered them in my street shoe size and they are a comfortable, relaxed fit. It probably wouldn't hurt me to go down a half size. The problem is that even different models from the same manufacturer can have a wildly different fit. For example, the 510 spires are about 2 inches longer than the 510 Anasazi lace-ups. I thought it was some kind of joke when I pulled the Anasazis out of the box and was near the point of crying when I put them on. But, some folks like that type of fit.

Sizing can be tricky, but I'd suggest going a half size smaller and trying the 9's. These are leather which will stretch quite a bit as they break in; Evolvs are synthetic which does not give nearly as much. Of course the size you end up with will depend on the type of fit you are looking for. It can be a good idea to order multiple sizes and just return those that don't work.
