A favorite of thru-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, Smartwool pulled out all the stops: the 4 Degree Elite Fit System provides a dialed fit and the 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.
