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.

My new favorite socks! True to size, fit perfectly, and the best part is they do not slide off your foot! 10/10 recommend!

Great sock liners

Awesome socks. Has little gel pad on top of heel for no slip. Thin and comfortable. Previously Purchased at Nordstrom rack and no longer in stock. Happy to find here
Note: Will shrink a little best to air dry
