Made from Merino wool and recycled plastic bottles, these Soft Black clogs from Rothy's are machine washable. The footbed is soft and contoured, with arch support and toe grip. Rothy's suggests you order one full size down which I didn't. They are labeled size 6 and they are just too big for me. Because they are too big for me, I didn't wear them more than twice. They are in great shape and need a size 7 foot to fill them. Photos are part of the item description.
