Puma Deviate NITRO 4 Trainers - Green/Yellow - UK 9

Yes, the advanced cushioning and responsive nature of the NITRO foam make them well-suited for marathon distances on road surfaces.

These trainers are specifically designed for road running. While they might offer some grip on light trails, they lack the aggressive tread and protection needed for technical or uneven trail surfaces.

Use a soft brush to remove loose dirt. Then, use a damp cloth with a mild soap and water solution to gently clean the affected areas. Rinse the cloth and wipe again to remove soap residue, and allow to air dry.

NITRO foam provides a combination of lightweight cushioning and high energy return, leading to a more comfortable and propulsive running experience.

UK 9 refers to the UK sizing standard for men's footwear, indicating the size of the shoe for the United Kingdom market.

This specific product listing is for the Green/Yellow colorway. However, the Deviate NITRO 4 series may be available in other color options from Puma.

It is generally recommended to replace running shoes every 300-500 miles (480-800 km), or when you notice significant wear on the outsole or a decrease in cushioning and support.

Loosen the laces and try re-lacing them, ensuring they are not tied too tightly. If the issue persists, consider if this is the correct size or width for your foot. Check for sibling variants in different sizes or widths.

While NITRO foam is durable, its responsiveness can be affected by heavy use and mileage. Ensure the shoes are clean and free of debris that might impact performance. Consider your total mileage; athletic shoes have a lifespan.

Ensure the shoes fit correctly and that you are wearing appropriate running socks. Break in the shoes gradually with shorter runs before attempting long distances. If discomfort persists, it may indicate a need for a different shoe model or support type.
