I bought a pair like this in a womens size for myself a while back because I wanted some warm slippers for my perpetually, freakishly cold feet. I stopped wearing them because they were so hot and made my feet stink. Maybe the stink was just normal foot odor, but since my iceblock feet had never sweat before, I was alarmed.

When the boyfriend put these on the wishlist, I warned him that hed probably have the same issue. But he didn't listen (shocker). He wore these slippers for maybe half an hour, and when he took them off, I had to open a window. The cat, who regularly eats garbage and licks its own anus, ran from the room in disgust. They were returned, for the sake of our relationship.
