Great Heel Socks
Material Type: Black - 3 Pairs, Size: Large
I don't know how they work but it's wonderful. I've had rough heel problems for a long time. I wear these everyday and my heels are not rough. They're not baby bottom smooth, but they are not ever going to be. These heel socks also oncce they are properly positioned snap onto the heel. Properly positioning them is easy when you put them on your foot with the heel cup in the correct orientation.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

Good fit
Material Type: Black - 3 Pairs, Size: X-Large
My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.

No more painful cracked heels! These really do work!
Material Type: Black - 3 Pairs, Size: X-Large
These really do work well. This is one of the first winters that I have not experienced painful, cracked heels. They are long lasting, and definitely make my heels smoother and softer after wearing them. For the first few times wearing them I simply went with the moisturizer embedded in them. After a few uses I then covered my heels with Aquaphor Advanced Therapy Healing Ointment. This worked even better, and I would recommend it. I am very glad I bought these. Of note, I have really big feet that are quite wide and the XL are a little snug but not uncomfortably so. I use them overnight, but also have worn them under socks and they work fine.
