On Running Cloudswift 4 - Grey - UK 10.5

The Cloudswift 4 is primarily designed for `road running` and daily training, offering a balanced combination of cushioning and responsiveness. While versatile for various 'adventures,' it performs optimally on paved surfaces rather than rugged trail conditions.

The `nylon-blend Speedboard®` is a lightweight plate embedded within the sole. It works with the `Helion™ superfoam midsole` to convert impact energy into forward propulsion, creating a more responsive and efficient toe-off with each stride.

The `dual-density Helion™ superfoam` is engineered to provide superior cushioning for soft landings while simultaneously offering high energy return for a responsive push-off. This unique combination helps reduce impact and enhances the feeling of forward momentum.

Yes, the upper of the Cloudswift 4 is made from `recycled polyester`. This commitment to using sustainable materials helps reduce environmental impact without compromising on breathability, durability, or comfortable fit.

A single On Running Cloudswift 4 shoe weighs approximately `278g`. This lightweight design is intended to minimize fatigue, making the shoe comfortable for extended use and longer runs.

The general recommendation for replacing running shoes is every 300 to 500 miles, or roughly every 4 to 6 months if you run regularly. Signs like diminished cushioning, worn-out tread on the `rubber outsole`, or new aches/pains can also indicate it's time for a new pair.

Ensure you are wearing high-quality, moisture-wicking running socks. While the `breathable one-piece upper` is designed for ventilation, proper sock choice is critical for foot comfort and managing moisture.

Check your lacing technique. Experiment with different lacing patterns to alleviate pressure on specific areas of your foot. Ensure your shoes are not tied too tightly. Although designed for immediate comfort, allow for a short break-in period if new.

Running shoes have a finite lifespan. If the `Helion™ superfoam midsole` or `Speedboard®` feels less effective, or the tread on the `rubber outsole` is significantly worn, it may be time to replace your shoes. Info needed: Consider your total running mileage on the shoes; typically, shoes need replacement after 300-500 miles.
