Inspired by the deserts and sunsets into which Ultra Runner Michele Graglia runs, the Mickey Pro Series is our new flagship ultra trail sock. The hot and cool tonal range is a nod to Mickey being the first person in history to win both the hottest and coldest foot races on Earth. A Guiness World Record holder for runs across the Atacama and Gobi deserts, Mickey won the Yukon Arctic Ultra in temperatures below -40AdegC (-40AdegF) and the Badwater 135 in Death Valley, with highs above 54AdegC (130AdegF). Crafted from our Signature Merino Blend, this 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. A zero cushion profile and 3/4 crew height balances breathability and protection. The Definitive Fit System(TM), our proprietary foot moulding Memory Stretch(TM), ventilation panels for airflow and an anti-wrinkling, elasticated instep combine for a comfort epiphany.
