I have them in black and white. I use them everyday in all shoes. These are very versatile and a great quality material. They take a looong time to wear and they stay in place. Very washable and good material. They are not too thick and they do not shrink. I do air dry mine. They do not hold smells even in the summer heat.

Best socks!

I love these socks! They last for years and they fit so nicely on my feet. I love that I can wear the in tennis shoes or wool boots and they never move!
