The only no show socks I have ever found that do not slide down. These are very comfortable and the extra tab on the back provides comfort by keeping shoes from rubbing the back of your foot. The top of the sock also comes up high enough to cushion the top of your foot all while still remaining hidden while wearing tennis shoes or even with my hey dudes.

Favorite Socks Ever

Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted

I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

Great ankle socks that stay put at a great price!!

Size: 6-9, Color: Assorted

These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!
