Bought for my wife as she starts off climbing. Sizing on these runs true to size as far as I can tell, so you probably don't want to follow the conventional wisdom of going a few sizes small. I'm sure they'll stretch given that they are unlined leather, but she complained loudly about even a half size smaller (she's a 37.5/6.5 and the 37 was pretty painful, but her feet are on the wider side in the ball/toe area). I expect these to be pretty comfortable for her once broken in.
