favorite of through-hikers and day-trippers alike, the PhD Outdoor Light Mid Crew packs some serious trail power. This lightweight hiking sock features Indestructawool technology for ultimate durability in high wear areas, Smartwool's 4 Degree elite fit system for a dialed fit, and their 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 their women’s-specific fit provides an overall slimmer fit and narrower heel. All of these features work together to create one of their best-fitting socks.
