I recently started the switch to clipless. I got Shimano 520 pedals and Shimano M021 shoes. I have to say I love clipless, its awesome. But I have found that i need thinner socks than the socks I wear on a regular day to day basis. Does anyone have any suggestions for good thin socks for biking? I dont want to spend $20/pair either. I dont plan on riding through mud, mainly just rode w/ trails.
