Those socks are great. I have some from hospital stays, but I never opened them up. They are for PT in the hospitals where shoes are not commonly worn. I don’t slip much at home, but they are kind of cool.
Incidentally, they are color coded with red intended to indicate that the wearer is a definite risk for falls. Anytime you see a Patient wearing them, you should pay a bit extra attention for their safety. Mostly they would have someone walking with them for support in maintaining balance.
I bought him a bunch of the diabetic no-slip socks the last time he fell but he won’t wear them. He said they make his legs swell, even though they are loose at the top. They aren’t the anklets like the hospital had on him. I have never seen any swelling, but I did tell him that walking around might help with the swelling, even if there isn’t any. 🙄 His oxygen levels and breathing are a lot better! When that is better, he’s not a dizzy.
