    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.

    Stains easily. Tight for men's size 11 feet
    Flavor Name: XL silicone socks 2 pairs, Flavor Name: XL silicone socks 2 pairs
    Husband wore dark cotton socks over these gel foot covers overnight and the covers picked up color from the socks. Tried hand washing, even dabbing with a bleach soaked paper towel, but the stains remained. The covers are a bit tight for men's size 11. Edit: After a few more hand washings the stains began to fade. However one tore around the leg opening when taking it off.
