Universal recovery left right foot Black Medical Boot

Adjustable black medical boot with secure straps. Features a blue circular accent. Designed for comfort and support. I bought for myself but got the wrong size. This says medium. I wear a size 9-9.5 womens and I would say this boot fits better a size 7.5-8.5 womens Brand new never used. I tried on and it didn’t work for me. I just not able to return.
