UGG boots youth size

Soles in great shape beside being dirty from wearing. It was the largest youth size when bought, I usually wear size 8-8.5 and my feet can go in but of course tight so the sizing on runs larger than usual. I think adults who have smaller feet can wear this. The tracks on the soles still have plenty left from not wearing much. Well constructed, sturdy, functional and beautiful.Bought brand new was over $500. Waterproof says on the back of the shoes. Ask questions and no returns.
