The On Cloudflow 5 AD is a high-performance running shoe engineered for speed and stability on road surfaces. Featuring On’s signature CloudTec® sole with hollowed-out 'Clouds' for responsive cushioning and explosive energy return, the midsole combines lightweight EVA foam with a TPU Speedboard for propulsion and torsional rigidity. The upper uses engineered mesh with seamless overlays for breathability, lockdown, and durability—reinforced at high-wear zones. A sleek monochromatic black design includes subtle reflective accents and the iconic Swiss flag tag on the heel, signaling On’s Swiss heritage. The AD (All-Day) variant enhances daily wear comfort without sacrificing performance, making it ideal for tempo runs, interval training, or urban commuting. The outsole features strategically placed rubber pods for traction while minimizing weight. Size 8.5 US (EU 42), made in Vietnam, these shoes offer a snug yet adaptive fit with a medium-to-narrow last. Perfect for runners seeking a balance of speed, support, and minimalist aesthetics—equally at home on city streets or paved trails.
