Marathon Active Advantage Heather Slate features true graduated compression which increases blood flow and allows you to perform at your peak, recover faster and feel better sooner. This style features a thin white stripe near the cuff as well as Active branding near the heel. Look amazing without the added warmth of wool during late spring and summer months. Our advanced design supports critical muscles and tendons, and our proprietary blend of materials wicks moisture for a comfortable fit that goes the distance.
