Lenz Heat Sock 7.1

Cold toes left all of us feeling quite grinchy after a day out on the hill back in times of yore, but the advent of heated socks brought choruses of "Hallelujah!" from the Whos. Still, not all was well in Whoville, as some members of the Mount Crumpit Skimo Team felt the price of ill-fitting boots was too high for the comfort of warm toes and were left to suffer through brutal midwinter practices. The innovators at Lenz have heard their pitiful cries. The new Heat Sock 7.1 features an especially thin knit weave (89% polyester, 11% elastane) optimized for performance and race boots, vanquishing the choice between fit and comfort forever. Like the 6.1, the 7.1 socks can provide heat up to 22 hours using the Lenz Lithium Battery Pack , and the exact temperature can be adjusted to personal preference on the Lenz app or on the battery itself. All this in a thinner package that will not change the fit of your carefully dialed performance set-up. Hallelujah, for the Lenz 7.1 indeed.
