My problem with "unisex" shoes/boots is twofold. First they are generally narrower than men's for the same length. Second, very few are made in women's sizes above 12 (US). I wear a men's 13E

Bought a pair of dancing gillies, size 15, and had to stretch the bejabbers out of them to get them to fit. Fortunately one can do that to thin, soft leather (goatskin, I would guess).
