Bridgedale's 3/4 Crew Ultralight Merino Socks are great for long days out in the Eastside when you are moving quickly. The ultralight socks have targeted micro cushioning to support, only where it's needed. The over-foot ventilation and moisture management technology will keep your feet cool and dry at every mile. As a trail sock, Bridgedale has included its 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!
