Ribbed介護 socks with non-slip grips, available in gray and blue. - Brand: B.O.P.S. - Colors: Gray and Blue - Design: Non-slip grips - Material: Ribbed knit - Use: Socks for casts - Quantity: 3 Thank you for viewing. I used these a few times while wearing a cast after rupturing my Achilles tendon. They have been washed. Your toes won't get cold even in the winter. I think they're good for hiding the whiteness of the cast. It's also possible to split them into 1 or 2 pairs. Please contact me if you have any requests.
