So So Socks
Size: Regular, Color: Cream
These are very comfortable socks. I machine washed them on a gentle cool water cycle and they ravelled. That is disappointing quality.

Wonderful for dry feet
Material Type: Black - 3 Pairs, Size: X-Large
I have been dealing with dry skin and problems with the heel of my foot, so I thought I would give these a try. I am so glad I did. They moisturize beautifully. A must is you are having trouble with your feet.

X-Large is about a size 12-13 shoe size foot USA.
Material Type: Black - 3 Pairs, Size: X-Large
I love them they work fantastic. I am a big guy with swollen feet. Wear size 12 to 13 USA Shoes. They fit me just fine not tight. My feet felt good after wearing them for two days. Some dry skin pulled off with them and it says to wash by hand. I dont know about the durability but I am hoping to get about 5 uses per pair. Before they become unusable.
