The SmartWool PhD Mountaineering Socks fit smoothly, comfortably, and easily into your low-volume mountaineering or hiking boots for incredible comfort when you bag peaks and tackle rough terrain. These heavyweight socks feature temperature-regulating merino wool fabric, strategically placed mesh ventilation zones, and a heavy-duty heel and toe.
You have to stay dry, warm, and comfortable while bagging fourteeners, so pull on the SmartWool PhD Mountaineer Sock and make your feet feel good. The 4 Degree Elite Fit system puts bands on the ankle, upper instep, lower instep, and the arch keeps the socks in place and offers greater stretch and recovery, while high impact zones in the toe and heel are beefed-up for longer wear and greater comfort. Meshed vents provide ventilation areas for moisture management.
