I have been in love with merino wool for a long time. Maybe 5 years ago I got some Ecosox from a sporting goods store but they quit handling them and they were the best socks I ever wore. When I found these I bought a bunch and I'm in love again. These are easily as good as merino wool and half the price. Bamboo works as good as wool and I love these. I highly recommend these to anybody that works on their feet all day.
