The Mobile Warming Merino 2.0 Heated Socks deliver advanced warmth through ultra-thin, flexible heat pads powered by lightweight rechargeable lithium-ion batteries. Made from a premium merino wool blend (54% Merino Wool, 37% Nylon, 6.6% Polyester, 2.4% Lycra), these over-the-calf socks combine natural softness and insulation with modern heating technology. Heating elements are positioned under the toes, providing targeted warmth where you need it most.

Each pair includes two Powersheer Pro Wireless 4000mAh 3.7V lithium-ion batteries that fit securely in a discreet YKK zippered pocket at the calf. A wireless remote lets you toggle between three adjustable heat settings (90° to 135°F) without breaking stride. The batteries deliver up to 16+ hours of heat per charge (5+ hours on high, 8+ hours on medium, 16+ hours on low) and charge via USB-C in approximately 4–5 hours.

The reinforced heel and toe construction adds durability in high-impact areas, while Sweatsheer moisture-wicking mesh liner keeps feet dry during active use. Odorsheer antimicrobial technology fights odor buildup, and Zapsheer static-dissipating fibers reduce static cling. The socks are machine washable on cold with a gentle cycle and tumble dry on low heat. Available in sizes Medium, Large, and XL to fit men's shoe sizes 5–13. Each set includes two heated socks, two rechargeable batteries, one USB-C charging cable, one wireless remote control, and a user manual.
