Description Cody Townsend&';s award winning pro series sock re-invented what a snow sock could look and feel like. 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(TM) and our proprietary foot moulding Memory Stretch(TM) 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.
