SmartWool PhD Outdoor Light Crew Socks are the highest performer in the mens SmartWool socks line, great for trail running, hiking, mountain biking and more. Crew sock height is the second highest in the SmartWool line, coming up to traditional crew height below the calf, keeping dust and dirt off your skin. Made of the all natural, odor free, moisture-controlling Merino wool fibers for which SmartWool socks are famous. Wool-on-Wool (WOW) technology puts more SmartWool in high-impact and high-wear areas to help reduce shock and abrasion, making these performance socks a lasting pair. SmartWool's 4-Degree Fit System means special attention to ankle, arch and insteps to keep sock in place - no bunching or slipping with this pair!. Strategically placed mesh zones provide maximum foot ventilation. 100 percent SmartWool fibers against your skin absorb sweat in its vapor state, which means sweat never condenses to make your feet wet and clammy, and odor-causing bacteria won't build up. Height: Crew. Cushioning: Light Half-Cushioned. Materials: 77 percent wool, 22 percent nylon, 1 percent elastic
