This is a neoprene medical ankle support. It's for the right foot, size L. I wore it for about two months after a fracture, and it's relatively clean and still in good condition. It comes with two plates to fix the ankle. After the cast was removed, I wore it during rehabilitation, as recommended by my doctor, and used it to practice walking. The original price was nearly 7,000 yen. The neoprene fabric is somewhat stretchy, allowing for size adjustment. Regarding the size of my healthy foot: The ankle circumference is 25cm, and it can be closed with about 5cm of extra space. The circumference of the mid-calf is about 35cm, and it fits just right. The height of the support is 23cm. The depth is 13cm. - Type: Ankle support - Material: Neoprene - Design: Padded with mesh material - Adjustable: Velcro closure Thank you for looking.
