Heated Socks - L/XL - 3 Levels - 9 Hours - Black/Gray

Keep feet warm for everyday wear and outdoor work with these L/XL heated socks. Integrated heating zones deliver warmth to the toes, instep, and sole, while a simple on/off button lets you select from three heat levels as conditions change. Battery life can provide up to 9 hours of heat for extended comfort. The over-the-calf fit with ribbed cuffs stays securely in place and layers easily inside boots. Matte black knit with subtle gray accents maintains a low-profile look. The machine-washable design makes care simple. An oval stitched panel at the shin adds structure without added bulk.
