On Cloudswift 4 - Black - UK 9.5

The Cloudswift 4 is best suited for daily training runs, road running, and urban environments. Its cushioning and responsiveness make it ideal for comfortable mileage and recovery runs.

The dual-density Helion superfoam midsole provides a balance of soft landings and energetic propulsion, absorbing impact and returning energy to help you run comfortably and efficiently.

While you can certainly race in them, the Cloudswift 4 is primarily designed as a comfortable daily trainer. For competitive racing, some runners might prefer lighter, more aggressive shoes with a firmer feel, but it depends on personal preference.

Clean your shoes as needed, especially after running in dirty or wet conditions. Gentle hand washing with mild soap and cold water is recommended to maintain their integrity.

This particular model of the On Cloudswift 4 weighs 278g.

The nylon-blend Speedboard acts as a flexible plate within the midsole, designed to load and release energy with each step, providing a responsive 'kick' and helping to propel you forward.

Check your lacing to ensure it's not too tight or too loose. Experiment with different lacing patterns. Also, ensure you are wearing appropriate running socks that wick moisture and prevent blisters. If discomfort persists, verify the shoe size and width are correct for your foot.

Running shoe midsoles have a lifespan. While the Cloudswift 4 uses durable Helion superfoam, persistent heavy use can lead to compression. Consider the mileage on your shoes; most running shoes last 300-500 miles. If they are past this range, it might be time for a new pair.

Try using a 'runner's knot' or 'heel lock lacing' technique. This involves using the top eyelets to create a loop that snugs the shoe more securely around your ankle, preventing heel slippage.
