In reply to owensum:
My twopenneth - I have very slim, low volume feet and have real trouble fitting boots. Lace ups are the only way to go, with the laces going as far down to the toe as you can find. To date Ive worn la sportiva mythos (my first shoe), Scarpa Visions (if you can find these, buy them), and am now in Anasazi greens (couldnt stand the pinks, they were tortuous).
I have found no real difference between mens and womens shoes btw. Womens shoes can be just as baggy.
Good luck!!
