Hardcore backpacking boots take an agile step forward with the St. Elias GORE-TEX® Although it's our lightest backpacking boot, the St. Elias is built to bomb. To begin, we combined traditional comfort and support with a cutting edge, weight-optimized sole. And then we got creative: the midsole incorporates a soft EVA bed which allows the sole to conform precisely to the irregularities of the trail. The result? Ridiculous traction and a feel (both out of the box and out on the trail), that's unlike anything that's come before.
