Frequently Asked Questions

• How do I pick the right On Running hat for hot-weather runs?

  Choose a lightweight, low-profile On running cap made from breathable polyester or polyamide blends with mesh vents and a moisture-wicking internal sweatband to keep sweat off your face. Look for an adjustable closure (hook-and-loop or strapback) so the fit stays secure at higher speeds, and opt for a brim length that balances sun protection with airflow depending on your route.
• What should I look for when choosing On Running socks for long runs versus everyday training?

  For long runs prioritize socks with targeted cushioning in the heel and forefoot, seamless toes, and moisture-management fabrics (merino blends or polyester/elastane mixes) to reduce hotspots and blisters; On’s performance-oriented sock variants add reinforcement in high-wear areas. For daily training choose lighter, lower-profile On socks with breathability and odor-control treatments for comfort across many miles.
• How do On Running gloves differ for cold-weather training and touchscreen use?

  Cold-weather On gloves typically use a fleece or brushed lining with wind-resistant outer panels and an articulated fit to retain warmth without bulk, while touchscreen-compatible models incorporate conductive yarns on the thumb and index finger for phone use. If you plan intervals or varied conditions, look for gloves with breathability and a short cuff that layers under a jacket sleeve.
• How should I size On accessories like hats, gloves, and socks for the best performance fit?

  Measure head circumference at the brow for hats and hand circumference around the knuckles for gloves, then follow On’s size chart—choose adjustable hats for margin and size up in gloves if you’ll layer liners underneath. For socks, select the size that matches your shoe size and prioritize stretch and heel fit; a snug, non-bunching fit prevents blisters and improves proprioception.
• How do On Performance socks compare to On Lightweight running socks, and which should I buy?

  On Performance socks offer more targeted cushioning, reinforced heels/toes, and slightly thicker fabrics for longer distances and recovery runs, whereas On Lightweight socks prioritize minimal weight and maximum breathability for speed sessions and race day. Choose Performance for comfort on extended outings or if you prefer extra protection, and Lightweight for fast workouts or hot-weather runs where ventilation and low bulk matter most.
