On Cloudrunner 2 - Grey - UK 9.5

The Cloudrunner 2 is ideal for adult runners seeking maximum cushioning, comfort, and stability for their daily training, long runs, and recovery sessions. It's suitable for neutral runners and those needing mild support.

The use of 100% recycled polyester in the upper (and 30% total recycled content) does not compromise the shoe's performance. On has ensured that the recycled materials meet the same high standards for durability, breathability, and support as virgin materials.

The On Cloudrunner 2 has a heel-to-toe offset (drop) of 10mm. This higher drop is common in highly cushioned training shoes and can benefit runners who strike with their heel or midfoot.

To clean your Cloudrunner 2s, gently brush off loose dirt. For deeper cleaning, use a cloth dampened with a mild soap and cool water solution to wipe the upper and midsole. Avoid machine washing or drying, and let them air dry naturally away from direct heat.

While the Cloudrunner 2 offers good energy return and is relatively lightweight for its category, it is primarily designed as a cushioned daily trainer. For competitive racing, you might prefer a lighter, more aggressive shoe focused purely on speed.

CloudTec is On's signature cushioning technology, featuring individual 'clouds' that compress to absorb impact and then rebound. Helion Superfoam is the specific, advanced foam material used within the midsole, providing a luxurious, energetic, and lightweight cushioning experience. In the Cloudrunner 2, they work together for enhanced performance.

For a structured and highly cushioned running shoe, the Cloudrunner 2 is considered lightweight, weighing approximately 277g (for a men's UK 9.5). This balance helps reduce fatigue over long distances while maintaining protective cushioning.

Ensure you are wearing appropriate moisture-wicking running socks. The breathable mesh upper is designed for ventilation, but cotton socks can trap heat and moisture. Consider lighter socks or adjusting your running schedule to cooler parts of the day.

While the Helion Superfoam and Speedboard provide significant energy return, ensure your running form allows for efficient transitions. Also, give the shoes a few runs to fully break in and for the cushioning to adapt to your stride. Check that the lacing isn't too tight, which can restrict foot movement.

While the new outsole significantly reduces stone trapping, it may not eliminate it entirely, especially on very rocky or gravelly paths. After your run, quickly check the outsole and manually remove any small stones with your fingers or a blunt object to prevent them from digging deeper or affecting your next run.
