A favorite of through-hikers and day-trippers alike, the PhD® Outdoor Light packs some serious trail power. Featuring a versatile, multi-sport design, this lightweight style includes Indestructawool™ technology for ultimate durability in high wear areas. And when it comes to comfort, we pulled out all the stops: the 4 Degree™ elite fit system provides a dialed fit and our signature Virtually Seamless™ toe offers extraordinary comfort in any trail shoe. The mid crew silhouette sits at an ideal height for a low trail boot while the women’s-specific fit provides an overall slimmer fit and narrower heel.
