Details

• Targeted Under-Toe Heat Focus: Engineered with advanced, ultra-thin heating wire arrays positioned underneath the toes and front base of the foot to stimulate circulation and prevent numbness in sub-zero winter weather.
• Up to 22 Hours of Active Warmth: Powered by ultra-slim, energy-efficient 3.7V rechargeable lithium-ion battery packs that carry you comfortably through long work shifts, multi-day camping trips, or full days on the slopes.
• Smart App & Push-Button Control: Gives you dual control options to adjust thermal output on the fly; seamlessly shift temperatures using the integrated manual button loop or use the wireless smartphone app without unbuttoning layers.
• Moisture-Wicking & Anti-Odor Tech: Knitted from high-density, technical compression fibers that actively pull sweat away from the skin to block thermal drops, paired with a natural barrier layout that blocks odor-causing bacteria.
• Calf-Contoured Boot Comfort Fit: Outfitted with lightweight, specially curved battery cells that rest flat against your leg, preventing slipping, chafing, or interference when tucked inside tight ski boots or heavy work gauntlets.
