I love Smart Wool, and I love these socks! Comfortable, stay in place, provide a small amount of padding. I've worn them for hiking, walking, working out, and just around. They are breathable and keep my feet warm on the bare floor if I need a bit of covering, yet stay cool in my hiking shoes and sneakers as well. They do not fall into the 'ultralight' category however, in my opinion. Maybe 'light'. Still love them though! Also love Backcountry...great service, FAST and free delivery, easy returns.
