Black Diamond BD Medium Crew Merino Socks

A mid-cushion merino crew sock built for hikers and climbers running stiff approach shoes or low-cut hiking boots, the Black Diamond BD Medium Crew Merino Sock fills the cushion gap between the Light Crew and the Heavy Mid-Calf when the load and the boot demand more support than a thin sock provides. Extra instep cushioning runs across the top of the foot to absorb pressure from laces, lace bales, and hard-shell boot tongues, and the merino content resists odor across multi-day trips where a synthetic sock starts smelling on day two. Cushioning around the leg protects against the cuff pressure that turns a long approach into a heel-blister problem. The crew height keeps the sock under a low or mid-cut shoe cuff without riding up to the calf, which is the right sock for the load-carrying hike-in to a backcountry climb.
