Carhartt Men's Twin Knit Midweight Steel Toe Boot Sock (SB9360-M) is a work sock like no other thanks to Twin Knit and True Rib knitting technologies. Twin Knit combines a durable sock exterior with a moisture-wicking sock interior to keep your feet warm and dry. True Rib is a form-fitting sock ribbing that stays in place on your leg without compression. Together, your feet stay comfortable throughout the workday. Made for use in steel toe boots with a moisture-wicking, odor resistant and temperature regulating wool blend, these midweight men's socks were made for hard work. Designed to fit securely on your feet and legs, these steel toe boot socks have enhanced heel pockets and True Rib cuffs that stay put without squeezing or discomfort so you can focus on your job, not on your socks. Carhartt men's boot sock height is 14”. Available in Men's Large (US Shoe Sizes 9-11.5) and Extra Large (US Shoe Sizes 12-14.5).
