I love these socks!! I am self-professed sock-snob, although I'm on a budget. These work out perfect for me and I currently have 6 pair that I wear anywhere from hiking, running, work as business casual, out on the town, and skiing on warmer days. The material is awesome and very versatile in a wide range of environments. They fit snug to your feet but not crazy snug like I've experienced with some smartwool socks. I would say they are more of mid-weight hiking sock. The oldest pair I have of these are still going strong after a year of use. Pick up a pair of these, you won't regret it!!
