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 😎

Good socks they work.

Size: 2 pairs black L

I normally wear size 13&half to 14 men's, and these fit me ok. They sit just below the ankle. They can get a little tight for me so you should look out for that if you are on the thicker side. But they work as advertised and help moisturize your feet. I recommend wearing them if you're going to just be hanging around home for a bit in one spot as they can be a little slippery to walk in if you go fast. Would not recommend going up and down stairs.
