Purchased from a medical institution on June 19, 2025. I was instructed on how to wear them at the hospital and wore them for about 5 minutes on the way home. I had my size measured carefully before purchasing, but I can't put them on by myself... So, I'm putting them up for sale. The size is V. My calves are thick, so it's probably around a 3L size, which is usually not available. They are made to a professional specification, so the fabric is very sturdy. The open toe design might be good for preventing stuffiness.
