When you spend all day moving between your truck and job sites or deliveries, you need socks that hold up to extended wear. Carhartt's Twin Knit Midweight Topo Crew Socks hold up and more with Twin Knit yarn mapping that combines a durable exterior with a moisture-wicking interior. These midweight socks stand up to busy days with cuffs that stay put without compression and secure-fitting heel pockets. The wool blend knit naturally regulates temperature while wicking sweat and resisting odor. Whether working, hiking, or camping, cushioning and reinforcement at the heel and toe supports long days on your feet and extends the life of the sock. The subtle topographic (topo) design is inspired by mountains and gives these men's socks their name. 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 SC9820-M.
