the HiFi Quarter Crew

Lightweight feel with a little more leg than our classic crew. Engineered to create a cooler, drier microclimate around your foot. CourierPOD mapped cushioning and airflow system for targeted impact protection without bulk or overheating. Knit "Sunroof" on toe box that allows natural splay and prevents toe cramping. Ultra-lightweight performance with a little more leg. The HiFi Quarter Crew is a lightweight performance sock built designed for speed, support, and breathability. With targeted cushioning (courierPOD™ technology) to reduce impact on the forefoot, arch, and Achilles, plus a vented “Sunroof” panel for optimal airflow and natural toe splay, the HiFi helps you stay cool, comfortable, and blister-free on every mile. Anatomical fit and graduated compression deliver locked-in support without restriction. Engineered to let you experience everything in your run and ride, staying connected, energized, and in perfect flow with every step, the Quarter Crew is everything you love about the HiFi, just with a different tan line.
