Exploring the great outdoors calls for great hiking socks. Our PhD® Outdoor Light Elite Colorado Crew uses targeted cushioning around the toes and heel and features our Indestructawool™ technology for enhanced durability, our 4 Degree™ elite fit system for a dialed, performance-oriented fit, and our Virtually Seamless™ toe for enhanced comfort. Its shin-high height helps provide in-boot protection and a Colorado pattern shows off our front-range home.
