This is a great idea, and I can wear socks over them and not notice they are there. I just wish they came in a larger size. When I put cream around the edges of my heels where the cracks always are, I cannot stretch the socks wide enough to clear the heel without smearing the cream onto my fingers or on the sock cuff. They do stay in place and aren't squishy at all when walking. They smell good too. The price is right. I wore them overnight and my heels were indeed much softer and smoother than before, and felt moist (tacky) where the cream had been. So they do an amazing job, but after using them six nights, they just aren’t large enough for me to put on without a hassle.

Works for foot psoraisis

Size: 2 pairs black L

Got these for work (service industry) to reduce issues with psoriasis and blisters while putting on 20k+ steps a day. Over time the wounds healed and I could work without so much pain. I now don't use them all the time like I used to, only when a new lesion or blister appears, too prevent a breakout. Tip: if you're not in full breakout, wear thick socks under these as a barrier to friction.

Work well but run small

Size: 1 pair black L

They do seem to run a bit small. I bought them for my bf but snagged them from him because I couldn’t resist! I’m about a W8/12 and they were just a little big but unlike others, I just put them on while sleeping and didn’t walk around with them. If you’re just planning on that, they did a great job at sloughing and moisturizing 😎
