These are brand-new, except for the one pair that I wore and didn’t realize I had purchased size SMALL when I needed a medium. I had torn the package up and threw it all away, so couldn’t return them. Check their website for sizing, but they were too short and tight on my size 8 feet, so should work for a size 6-7 shoe. One each of navy, gray, cranberry and black. The black ones have been washed, the others are untouched. All cotton (I think) or it might be a cotton/poly blend. Perfect for stocking stuffers! Will send in a clean ziplock bag.
