Smartwool PhD Nordic Light Elite Crew Socks

Size Chart

Whether it's a chilly winter morning or bluebird spring afternoon, it's always easier to get after one more lap when you're comfortable. PhD Nordic socks were designed with that long-distance comfort in mind, from mesh zones for ventilation to strategic cushioning in the toe and heel that provides extra padding without sacrificing boot fit. Smartwool has added Indestructawool Technology in high impact zones to increase durability, without the bulk. You'll also get a secure fit above and below the heel, under the arch and across the instep thanks to the 4 Degree Elite fit system. So keep on moving, because your PhD Nordic Light Elite socks have got comfort covered.
