No show but stays on
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.

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!!

Great quality, no holes or fading!
Size: Medium, Color: Black/Assorted
I purchased these socks a couple years ago and love them so much that I just recently purchased them again! They fit perfectly, don't make my feet sweaty, and hit the ankle at the right spot. The material is so good that over years they have not faded and even though I wear the same few pairs every day, they have no signs of thinning or holes! These are the ONLY socks that I buy. I have the black ones as well as the multi-colored ones. I will never buy another brand or style again!
