On Running Cloudsurfer Max - Black - 3.5

It's ideal for adult female runners who prioritize maximum cushioning and comfort for long-distance road running, recovery runs, or daily training.

CloudTec Phase is On Running's advanced cushioning system that uses computer-optimized elements designed to collapse sequentially, providing a smooth, soft landing and transition without a traditional Speedboard.

No, the Cloudsurfer Max is designed without a traditional Speedboard. The CloudTec Phase technology provides the cushioning and smooth transition directly.

The Cloudsurfer Max offers the most cushioning within the On Running lineup, prioritizing comfort for long efforts over a highly responsive or firm ride found in models like the Cloudboom Echo or Cloudflow.

While comfortable, the Cloudsurfer Max is primarily designed for comfort and cushioning. For dedicated speedwork or racing where maximum responsiveness is key, you might consider other models from On Running.

Clean them using a soft brush or cloth with mild soap and cold water. Avoid machine washing and allow them to air dry naturally away from direct heat.

Like most running shoes, the lifespan depends on usage, but generally, the cushioning and support are optimized for around 300-500 miles (500-800 km) of running.

This is normal for new shoes. The Cloudsurfer Max features a unique cushioning system that softens and adapts to your foot shape with regular use. Go for a few shorter runs to break them in.

Ensure you are tying a secure knot. If the issue persists, consider replacing the laces with a pair that offers better grip, or try a different lacing technique like a surgeon's knot.

The CloudTec Phase cushioning, while durable, will naturally compress over time. Consider replacing the shoes after approximately 300-500 miles, or when you notice a significant decrease in comfort and support.
