There’s something about trail running that can keep you going for miles — maybe it’s the quiet, or the scenery, or the adventure. But no matter how beautiful your surroundings are, nothing keeps you running like a breathable, soft, forget-it’s-there sock. Our ¼ Top Ultralight is the perfect trail running sock for warm days. The over-the-ankle height keeps trail debris out while allowing you to stay cool and comfortable. Hit the trail with these socks, then watch the miles fly by.
