Ultralight Alpaca Running Sock

The Ultralight Alpaca Running Sock is designed for runners who want a precise, breathable fit without sacrificing the natural technology of alpaca. Made with our patented Alpaca Dry Fusion Technology®, this sock moves moisture 85% more efficiently than Merino wool and is ASTM-certified antimicrobial, keeping your feet dry, cool, and stink-free — mile after mile. The naturally thermoregulating fibers adapt to your body temperature, providing lightweight warmth in the cold and ventilation in the heat. Unlike synthetics that trap sweat or wool that can itch, alpaca offers buttery softness, superior breathability, and odor resistance that never washes out. It’s the perfect sock for long runs, gym sessions, or everyday wear where performance and comfort meet.
