If you need a new pair of merino wool athletic socks, these babies were born to run. Their lightweight construction means no extra fabric, so there is just enough to cover your feet and wick away sweat, with a lightly cushioned sole to prevent blisters and cradle your footfalls. They barely show above athletic sneakers and will not slip or bunch, so you just might forget about these excellent running socks until it is time to take them off.
