Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.

Love these.
Number of Items: 3, Color: White (3-pairs), Size: Medium
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.
