Two pairs of socks that pull out all the stops, one Pine Green and one Rock Gray for double the performance. To make them, Wren consulted the experts and took notes on all the key must-haves for any performance-oriented pair. And they didn't just apply one or two of those features, no—they made sure these socks had every single one. That means breathable and naturally moisture-wicking merino wool, full terry padding from heel to seamless toe, and ribbed arch support that keeps the cramps away. The ribbed cuffs are built to stay up and stay put just below your calves—so you'll spend less time hiking up your socks and more time hiking.
