I ordered these because of previously good reviews, but, I'm not impressed! Playing the sizing game with various manufacturers is, apparently, a crap shoot at best.
I ordered size 13's, but they fit more like a size 12, and aren't particularly comfortable. Unfortunately, it took me a day of wearing them to realize that, so I'm stuck with them.
I'll probably just wear them around the yard.
I had received a pair of Merrill's recently as well, and they're noticeably better quality, although they run to the large side, rather than small. I'd first ordered a size 13 in the Merrill's, and they felt at least a half size too large!
Guess the lesson here is that you either go to a local shop that has inventory, or make certain to wear them only in the house for a full day before deciding whether to keep them or not!

4/3/13:
As stated previously, they felt too small initially.
However, after wearing them several times, they're not as tight as when I first wore them, and now fit more comfortably.
