tts, maybe a tad big. i've noticed in my last couple of wearings that my boots felt a little big (not uncomfortable or anything), it might be due to the fact that i'm not wearing thick socks with them. i definitely wouldn't size up.
TTS to a bit big. I generally wear a 7.5 (8 in some shoes, and 7 sometimes in others). I own my Campus boots in a 7 and I couldn't be happier with them!
