They are marvelous! They are thin yet warm; soft yet durable; tightly woven yet breathable.... They keep me warm and comfortable all day, and I even sometimes sleep in them - without sweating! For Christmas - both last and this year - I gave every family member a pair (counting 30 people in sum), and they all love the socks. They have become my first choice for birthday or hostess present for girlfriends - and although receiving socks may seem unusual, several of my friends have asked me to order more pairs from socks2go. I can only give socks from socks2go my best recommendations.They beat them all :) Kathrine V. - Denmark
