MARES Scuba Flippers

Scuba Flippers by MARES. They are 21-1/2" LONG (without strap). 9" wide at bottom. The black foot pouch is 9" long and the strap is adjustable, so it gives you a few additional inches. I wear a 9-1/2" to 10 shoe and they were good but room for a bigger foot. Even though they are well used, they are so comfortable that I traded a much newer pair for them with the divemaster. Unisex. Can't find a size.
