I have two sets. One of the thin summer ones, and one of the thick winter ones. I love these socks. After several washings they are as good as new. They fit perfect and are great!!! You want to talk about great customer service well let me tell you guys about my experience. Well I ordered a whole set of the summer thin ones. When they came I thought they were a little too thin for my tastes. I emailed them asking if I returned them and sent the difference in price if they would send me the think ones. They only wanted the 25 buck and told me to keep the ones I had and they would send me a second full set. I was very very happy!! These people are the best!!
