My feet are in love. These socks fit well, stay on without slouching down into my shoes on long hikes, and are unbelievably cool and lightweight. Wool isn't supposed to be cool and lightweight, is it? Doesn't that defy the laws of nature or something?

I have a few pairs of Smartwool brand performance socks in a similar style/price range that I do not like as much because they are binding at the ankle. These Darn Tough socks fit well, don't slouch, don't bind and come with lifetime guarantee.

I switched over to wool socks for the natural antimicrobial qualities. I was using socks that contained silver in the weave for antimicrobial protection, but read an article about how the silver particles can easily be released into the rinsing water from washing the silver weave socks and eventually end up in lakes and rivers where the silver deny beneficial bacteria of their natural life processes so I chose wool due to it being better for the environment. Wool is more expensive, but I have kids and I want them to leave the planet in as good a condition as possible for them when I'm gone.

The price tag on these is the only negative I can think of. The lifetime guarantee on these socks helps me handle the price better.
