A brand new high compression sock powered by our Calf Contoured 3.7v Powersheer Mini BT batteries that provides long-lasting warmth for up to 10 hours on a single charge. Our Pro Compression Heated Socks are a thoughtful blend of Fieldsheer Technology, and a thin Nylon fabric blend with added compression in key areas. Our Pro Compression Heated Socks take all-day comfort to the next level. Whether you’re in deep backcountry powder or an early morning job site, keep your feet warm and improve circulation to avoid stiffness, muscle fatigue, and soreness. With heavy cushioning in key areas and heating elements under the front of the foot, you can avoid the discomfort and numbness that come with being outside in cold conditions. The nylon/poly blend is breathable, and the full-calf length provides comprehensive coverage. Seamless Bluetooth connectivity powered by our proprietary MW Connect technology controls 4 heat settings, ensuring you maintain complete comfort. A wide array of compression throughout the calf, arch, foot, and heel provides relief, while the nylon fabric blend is thin enough for any ski boot or running shoe.Sock Features:Over the Calf LengthFits well in Ski/Snow BootsL/R DesignCompression in key areasArch SupportHeal and toe reinforcementNo slip featuresHeat under toesComfort Contour Bluetooth BatteryUp to 10 hours of heatBattery Features:Powersheer Mini B Rechargeable Lithium-Ion Comfort Contour Battery (3.7V 2200mAh)Up to 11 Hours of Power Per ChargeUL/CE certifiedBluetooth enabledBattery size: 8in x 1.8in x 0.5inUSB Charge Cable includedCharge Time 3-4 hours*
