adidas UltraBoot 4.0 DNA Trainers - Black - UK 9

While the UltraBoost 4.0 DNA offers excellent cushioning, it is primarily designed for lifestyle and casual wear. For dedicated marathon running, consider specialized running shoes optimized for performance and support over long distances.

Refer to the adidas sizing chart available online or from the retailer. It's recommended to measure your foot length and compare it to the provided measurements. Many users find they need to size up or down based on their foot width and the shoe's fit.

The Primeknit upper is breathable but not waterproof. While they can handle light moisture, they are not ideal for heavy rain. The rubber outsole provides good grip on wet surfaces.

'DNA' in the UltraBoost naming typically refers to a version that pays homage to the original design while incorporating modern updates and technologies.

The Chinese New Year theme is specific to certain colorways and releases within the UltraBoost 4.0 DNA series, indicated by the product description and specific color details.

Warranty information can vary by retailer. Typically, standard footwear warranties cover manufacturing defects for a limited period, often around 30-90 days. Please check with the retailer for specific warranty details.

Adjust the lacing system to achieve a more secure or relaxed fit. Ensure you have selected the correct size; refer to sizing charts if unsure.

Use a dedicated sneaker cleaner or a mild soap solution with a soft cloth. Test on an inconspicuous area first.

Clean the outsole with water and a brush to remove any accumulated dirt or debris that may be affecting traction.
