Built for mile-after-mile comfort, Hollow’s Alpaca Performance Ankle Socks deliver a secure, breathable fit that helps keep feet dry and protected through running, hiking, training, and other active pursuits. Made with 51% premium Peruvian alpaca fiber, these socks naturally regulate temperature, wick moisture, and resist odor as activity levels and conditions change. Fine-gauge construction and a higher stitch density create a smoother surface against the skin and inside the shoe, helping reduce friction and hot spots. Added cushioning at the Achilles and heel protects high-contact areas from rubbing, while the mid-ankle height provides added coverage without unnecessary bulk. Stretch nylon and spandex help create a locked-in fit that resists slipping and bunching.
