To create an ultralight sock that’s as comfortable as it is supportive, we took a hard look at the yarns themselves. Testing in warm-weather conditions eventually led us to Hydrogen, a buttery-soft microfiber that’s blended with Lycra to deliver a light compressive hold along the foot, ankle, and lower leg using our seamless construction. From there we targeted the arch, wrapping it with a ribbed band of airy mesh for further support and boosted breathability, along with a contrasting band along the Achilles for a clean finish.
