For lightweight comfort on those long runs, the Women’s PhD OUTDOOR Ultra Light Pattern Mini Socks have what it takes. The women’s specific fit features a narrow heel with a slim fit to avoid fabric bunching up in the shoe. The 4 Degree elite fit system is designed for performance thanks to the specifically placed flex zone at the ankle joint. Indestructawool technology features a durable fabric blend that uses merino wool for extended comfort that lasts. Mesh ventilation zones and ultra light cushion provide the breathability and lightweight feel needed when hitting the trail.
