For the runner who prefers a low-bulk fit but wants more from a sock. Meta™ delivers much more with a sculpted left/right specific fit, advanced meta pad for forefoot strike performance, and a hand-looped toe seam that is imperceptible. Made from the recycled fiber Sorbtek Repreve. Many runners are discovering the benefits of a light, thin sock that also offers padding under the forefoot. Thinner, lower bulk fit than the D-Evo.
