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.
- Indestructawool utilizes a proprietary yarn and construction method which strategically places Merino and reinforcement fibers where they are needed most. The result is the most durable and comfortable wool sock ever made.
- 4 Degree elite fit system uses two elastics for greater stretch and recovery. Narrower profile provides perfect women’s-specific fit
- Ventilation designed for end use: more mesh in Ultra Light and Light weights ensures maximum breathability, thermoregulation, and moisture management.
- 57% Merino, 40% Nylon, 3% Elastaine
