Comfort and durability

Socks work really good. I have very rough and dry feet that tear up my bed sheets. They hold up to my destructive feet. They are soft and comfy!

Cotton socks

I really love the cotton material. These socks are excellent quality, they don't wear out, my feet don't sweat, and they don't slip on the floor. I highly recommend them!
