My brother likes warm slippers that he can wear outside to the mailbox or whatever. I bought him the wrong size for Christmas, and before I could send them back my 86-year-old dad had appropriated them. My dad wears slippers everywhere, and he immediately recognized that these were much better made than the cheap kind he usually gets. My brother has wide feet, but he had me get a 1/2 size longer and says they fit great and are really "substantial". So both my guys are delighted with the fit and the quality of these.
