REALLY unsafe to walk around in these
Size: 2 pairs black L
They do what they are expected to do, but should only be used if you are stationary. The gel base makes for very unstable footing if walking around

These work
Size: 2 pairs black L
My husband loves these they help his very dry feet. As others have stated they are extremely difficult to walk in so have to be careful but they do work nicely.

Potential Fall Risk
Size: 2 pairs black L
While these socks do indeed help soften rough skin on your feet, there is a risk of falling while wearing them. Although they have treads on the bottom, which would indicate they’re safe to wear with nothing else, when you put moisturizer on and then wear them your foot can slip inside the sock . This causes you to lose your balance and fall, which happened to me. I’ve thrown them out.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.
