"Does anyone here with a slightly wider foot wear these?"
I'm a 9.5/ 10 C. (I used to be a B. That's what years of walking around will do to your foot.) I bought a pair of Mudclaws by mail, and tried on most of the other lines at a local running-shoe store.
The Mudclaws were far too small in the toebox, even though they fit me in all other ways. The others I tried on weren't much better -- with one exception. The Terrocs have the more traditional wide fit in the toes, and fit me beautifully in all directions.
They're a bit sturdier than the other lines, "almost like street shoe," as the salesperson proclaimed. The irony is that that makes them far more suitable for hiking on uneven, rocky, or otherwise difficult ground, especially if you're not used to hiking in trail runners. The 330's are still pretty light.
I've since gone in the opposite direction and now do most of my serious hiking in Vibram Five Fingers KSO's.
The Terrocs now serve me well as walkin' around shoes, but the Mudclaws are pretty much abandoned.
