When working outdoors in the heat, Carhartt's Lightweight Liner Crew Socks can reduce the risk of blisters and keep your feet comfortable. Made with moisture-wicking and odor resistant fabric technologies, these lightweight, polyester blend socks are designed for active feet. Stretch tops reduce leg tension and stay put, and ribbed channels improve leg ventilation. Breathable mesh insteps and reinforced heels and toes provide comfort and durability. These men's socks can also be worn as liners under another pair of socks for added warmth, making them a versatile addition to your workwear, for cold or warm days. Offered in 2 men's sizes: Large (US Men's shoe size 9-11.5) and X-Large (US Men's shoe size 12-14.5). The crew sock height measures 10”. Model SC9842-M.
