These are NOT primarily cotton. They're polyester with latex rubber/nylon mixed in, along with cotton. The blend is very slippery when walking on smooth floors, or even while in shoes. They are also incredibly thin and a little small for my size 13 feet.

INCORRECT PRODUCT INFORMATION

The table on this page shows "Primary Fabric: Cotton" but if you look at my attached photo you'll see that's incorrect. The primary fabric is POLYESTER... 78%, while cotton is 19%. That's why these are so slippery and don't feel good.
