Designed for everyday comfort with a fun, youthful print. Machine washable and breathable for all-day wear. size large but fits shoe size 4 to 10. I'm an adult shoe size 8.5-9 and they fit me fine (I bought a pack for myself) I do believe adult size 9 and 1/2 or 10. you may slip off the heel just because they're no show and not meant to be stretched to the max. both packs are brand new with tags!
