A favorite of through-hikers and day-trippers alike, the PhD® Outdoor Light Pattern Mid Crew packs some serious trail power. This lightweight hiking sock features Indestructawool™ technology for ultimate durability in high wear areas, our 4 Degree™ elite fit system for a dialed fit, and our signature Virtually Seamless™ toe for extraordinary comfort in any trail shoe. The mid crew silhouette sits at an ideal height for low trail boots while our women’s-specific fit provides an overall slimmer fit and narrower heel. All of these features work together to create one of our best-fitting socks.
