For feet. I used this when I broke my foot and had a cast, for use in the bath and pool. It can be used on either the left or right foot. It becomes vacuum-sealed so the cast doesn't get wet! There are non-slip grips on the sole. It was very convenient. I am selling it because I no longer need it after the cast was removed. *No instructions included Vacuum cast cover for safe bathing and swimming even when wearing a cast♪ ● Made of medical-grade latex, so it's durable and can be used repeatedly! ● Creates a vacuum seal to prevent water from entering, allowing use in pools and baths. ● Easy to use! *Do not use if you have a latex allergy. Please consider purchasing, as this is a used item that has been stored at home.
