Patagonia Ultra Lightweight Endurance Anklet Sock
I have worn these trail running, at the gym, playing soccer, hiking, around town, and lounging at the home. If I wasn't unemployed at the moment I would add to the one pair I have. Seems as soon as it comes back through the wash it is the first pair I grab to use.
Ultra-comfy, fast drying, excellent wicking capabilities, breath-ability beyond competitors socks(my feet sometimes feel clammy in similar socks while walking around town), and durable; hope they never change the design of these!
