I wanted something that would keep my feet comfortable, stay up on my heel, be a bit higher on the top of my foot. These socks tick all the boxes.

I use the sock in the gym and for running. I did not know what to expect with bamboo charcoal. Glad I tried it. Very comfortable.

Works well for me living in Seattle. I was concerned the no-show wouldn't work with my hiking shoes. So far so good.
