So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all.
The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day.
They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable.
Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.

The best no show socks
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.
