soft, comfortable, stretchy
Color: Black/Pink Assorted Locked-in Fit, Size: Medium
Seems like some high quality, lightweight socks. Very pleased with my purchase. They are very soft, they fit just right, and the material is somewhat stretchy.

Comfortable athletic sock
Color: White/Halo Gray Assorted Locked-in Fit, Size: Medium
Love these socks. Neutral enough colors to pair with tennis shoes for daily wear but still a fun pattern. Comfortable, and stay in place without slipping down. Fit true to size.

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!!
