Hotronic
The Surround Race Heated Sock is the thinnest in Hotronic's lineup, providing a snug and dynamic fit that aggressive skiers will appreciate. Crafted with merino wool and minimal seams, the sock delivers uniform, battery-powered heat around the entire toe box, unlike traditional heated socks that concentrate heat under the ball of the foot.
The lightweight, low-profile battery pack snaps to the upper cuff of the sock and delivers power for days on end. Slim, welded wires run from the battery to the heating element and Bluetooth connectivity allows you to adjust the temperature directly from your phone, whether you want to adjust mid-run or while sitting on the chairlift.
