Comfy but not no-show
Color: Black & Grey, Size: Medium
They feel good and are comfortable and warm, but they are not “no-show” as described.

Socks
Color: Blue & Green, Size: Medium
They are about what I expected for the price. Nice and warm, but they pill a lot and sit higher on my ankle than I'd like. Very cozy and comfy though. Great around the house, not really great for hiking though. Kinda thin after a few uses outdoors. Washable but not very durable.

Great socks!!
Color: Black & Grey, Size: Medium
Love these socks. I am on my feet all day and other socks sweat, my feet are uncomfortable. These keep the moisture way from my feet and they are soft too. These were a great find and I highly recommend them.

These are my favorite socks
Color: Blue & Green, Size: Medium
Theses socks are so comfortable perfect size and thickness theses were the only socks I took on a 2 week Ireland trip with me.
These are a great value for your money and they look so cute on, I could not find any socks in Ireland that were as soft and have the durability that these have.
I highly recommend! I am a sock lover also and picket about texture.
