I'll admit it; I'm a sock "ho-wah". My favorite cycling-specific sock (currently) is the DeFeet Woolie Boolie. Nice and warm, comfortable, fit well - what's not to like?During the summer I like a number of socks, mostly also from DeFeet, but I haven't decided on a favorite.For everyday use, I like a number of light hiking socks from various manufacturers, e.g., Wigwam, SmartWool, Thorlo, etc.
