Purchased my first pair almost a year ago. Now I wear nothing else everyday. Feel naked if I don't have my toes covered. I started out with the recommended sizing, however soon found that at size 10, I needed the largest micro they had. Once I found the size, I wear nothing else. Bought black pair for dress shoes. Ran 8 Half Marathons, 1 Marathon in 2007 and have 5 Half's so far this year... It is phun showing them to others... Super Sock.
