Socks with "Printed" in the name include Polyester in their Nylon and Spandex blend to allow designs to be printed onto the sock rather than knitted in. The presence of Polyester will give the socks a slightly different fit and feel. These socks are rated 20-30 mmHg like the Marathons in this collection. Run in spooktacular style in the Marathon Printed, Pink Sugar Skulls knee-highs bring vibrant Día de los Muertos flair with all the benefits of graduated compression—support, recovery, and standout style. Don't forget to grab a pair of the original Marathon Printed, Sugar Skull socks while you're here! All our socks offer true graduated compression, which increases blood flow and allows you to perform at your peak, recover faster and feel better sooner. Our advanced design supports critical muscles and tendons, and our proprietary blend of materials wicks moisture for a comfortable fit that goes the distance.
