Snoozies Soccer Slippers Extremely cozy Snoozies slippers with soft, fuzzy lining. Rubber printing on bottom to help prevent sliding - meant for indoors only. 100% Polyester. Great gift for players and fans. Adult sizing is women's but these make a great gift for men too. Sizing suggestion: If you are between sizes, size up. If you wear the upper size (so 10 of 9/10) but like extra room, you may want to size up.
