Merino wool socks - thanks to modern technology that makes wool as soft as synthetics - are hands-down the best at keeping feet warm, dry and comfortable. After being disappointed at the expense vs durability factor in other brands I've been impressed with the lower pricing and higher quality in these socks for running, hiking, biking and just kicking around. They only sell on their website, and launch new styles every few months.

Love these for Golfing!! In Oregon we have to play through cold and wet as well as pretty hot summers and these keep the footsies feeling perfect no matter what. (via Point6)
