I've been looking for a pair of thin, low/ankle socks for riding with my race boots, which are uncomfortable with the thicker "sport" socks out there. I also wanted lower socks because on a 100 degree day, the last thing I want is a knee high as the rest all come in. Comfortable - no blisters or pressure lines on my feet after a long day. They wicked away moisture and kept my feet dry. They did what they said. Sizing - I ordered small and they are perfect for my (women's) size 8 feet.
