Mens Slippers

These are brand new, I got them for my stepdad for Christmas, but they were too small and since I seem to have deleted the email and cannot remember where I purchased them, I can't return them, they say size 10-11 but they are way smaller and probably would fit an 8-9 better, it is a two pack gift set and the grey ones were tried on but not ever worn other than that, the black ones were not tried on or worn at all, they are soft sole slippers with fleece lining, they look super warm and cozy
