Thank you for viewing. I purchased this when my grandfather was hospitalized, but I am selling it because it was never used. It is new and unused, but it has been opened once. Also, the bag has some wrinkles and creases. Please refrain from purchasing if you are concerned about this, as it has been stored by a private individual. The size is L. The reference foot size is listed as 24.0-25.0cm, and the reference foot circumference is listed as approximately 22.0-26.0cm. Thank you.
