Bridgedale's Ultralight Merino Socks are great for longer days out in the Eastside when you are moving quick. The ultralight socks have targeted micro cushioning to support, only where it's needed. The overfoot ventilation and moisture management technology will keep your feet cool and dry at every mile. As a trail sock, Bridgedale has included their zero debris cuff to keep rocks and dirt out and prevent the socks from slipping. This is the sock for trail joggers and runners alike!
