Does anyone have these, and can they tell me how they fit? Are they really narrow, or do they have some stretch to them? I'm normally an 8 or 8.5 in shoes, but since these are suede, I wonder if they will stretch and an 8.5 will be too big? Thanks! I'm really in LOVE with these shoes, and they are a great price, so I'm hoping I hear good things about them.
