We're not saying you should swim in this Run quarter sock, but if you're training for a triathlon, you might be tempted. Moisture-wicking Merino Wool combined with mesh panels on top of the foot keeps things cool and dry. The Element's new tech foot offers a performance and blister-free fit that stays put for every stage of the race. And at that point, if you just like quarter socks, well, this is the one.
