These are kind of strange -- first, you have to order way up, as other reviewers have mentioned.  My husband usually wears a 10.5, but I followed reviewers' cautions and bought him a 12 in this boot, and they fit.  Second, your husband has to get used to the wide ankle that apparently comes with a slip-on boot.  Mine isn't used to this yet, and he might never be.  He commented today that these boots "might be good for taking the compost out," but not for hiking.  They do look good, however, and he says they're perfectly warm.
