These slippers run small. Make sure to go up a size to compensate for the smaller fit.Old Friend went above and beyond when they made the Adjustable Bootee Slippers size 7-13, 14, 15, and 16. For men who have wide feet they can finally have the EEEEE - 5E wide slippers their feet have been barking for up to size 14. With the adjustable strap men with a high instep find they can slip their feet into these big mens slippers with ease, and leave them on without any bothersome pressure on the front of their ankle too. Weather you are a man who is almost seven feet tall and need a size 16 slipper, or you have wide feet and simply need a size 8EEEEE slipper, try these on for and do you feet a favor.
