A sock built with the technical insight and direct skin track feedback from one of the world’s most respected big mountain turned backcountry skiers. Crafted from our Signature Merino Blend, the sock ensures exceptional breathability, temperature regulation and comfort by melding the luxuriously soft on-skin properties of Rayon from Bamboo and the unrivalled odour resistance of merino wool — meaning Cody can wear them for a week straight if he wants. The Definitive Fit System™ and our proprietary foot moulding Memory Stretch™ delivers a precise form fit, with a semi-compression zero cushion profile, ventilation panels for airflow on the bootpack and an anti-wrinkling, elasticated instep that doesn’t bunch underfoot. Innovative silicone strips on the heel and upper calf keep the sock locked in place, aided by a technically knit achilles support band that drastically minimizes heel lift while you hike, eliminating blisters and hot spots. Now entering its fifth season, we’ve made our biggest technical update to this sock since the original Le Send turned into the Pro Series. We removed the additional toe-box cushioning after feedback from Cody and the backcountry community that it was no longer necessary with modern touring boots. A revolutionary sock with a technical, yet natural aesthetic. Inspired by the sculpted peaks, shadowed chutes and fifty lines that Cody Townsend searches for.
