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.

Very convenient, soft, comfortable and does its job.

Size: 3 Pairs - Gray, Green, Pink

As a first responder being on your feet consistently in heavy boots really takes a toll. I buy new soles for my boots and noticed the inconsistency balance from heel to toe which caused cracked and dry heels. I was desperate to find an immediate solution and saw these. Received all the socks individually wrapped, I am a size 5 1/2 to 6 in women’s shoes and they fit so snuggly. They are convenient, they fit under my work socks due to them only covering a portion of the foot and heel, the inside where the heel is a soft rubber material that helps keeps it in place, as well as if you use ointment or oils. The socks are soft and very comfortable that at the end of the day you forget you are wearing them. They are also washable both in the washer or hand washed and it doesn’t affect the rubber material. Highly recommend especially after a foot spa day.

Perfect!

Size: 3 Pairs - Gray, Green, Pink

When my heel skin started cracking, I of course found the internet hacks that went along the lines of put some moisturizing something (cream, Vaseline) on your feet and put socks on and go to sleep. Somehow many issues. While putting on the socks, I already wiped off the moisturizer. It feels terrible. My sleeping self hates socks apparently! I always kick them off, the socks are covered in moisturizer, and it’s all over my blanket. Yuck! So when I found these socks I was unsure but willing to try. These are exactly what I needed! They have this gel-y coating inside that does not absorb the moisturizer, so it actually gets absorbed into your skin. They are snug without cutting off circulation, and along with kerasal, my heels are being healed! Could not recommend enough.

They keep sheets from getting greasy.

Size: 3 Pairs - Gray

These are good. I like that I can put lotion on my heels when I go to bed and not get my sheets greasy. They do a good job on that and a pretty good job keeping the moisturizer on. Since the toes are open, they aren’t hot. The gel doesn’t seem to do anything, though.
