Adidas UltraBoost Slip-On DNA Trainers - White/Black

Measure your foot length from the heel to the tip of your longest toe. Compare this measurement to the 'Foot Length' column in the provided size chart. If your measurement falls between two sizes, it is recommended to choose the larger size. Always order based on your usual European (EU) size.

While the Boost cushioning provides excellent energy return, these trainers are primarily designed for daily wear, comfort, and light athletic activities. For marathon running, dedicated long-distance running shoes with more specialized support might be more appropriate.

Gently clean the Primeknit upper with a soft brush, mild soap, and cool water. Rinse carefully and allow the shoes to air dry completely. Avoid using harsh chemicals or machine washing.

The main advantage is convenience. The laceless design allows for quick and easy on-and-off wear, saving time and effort, which is ideal for busy individuals or for slipping on after exercise.

The Primeknit upper is adaptive and can accommodate various foot shapes to some extent. However, if you have significantly wide feet, the slip-on nature might offer less adjustability than lace-up shoes. Trying them on or ordering your usual size with the option to return is recommended.

The 'Foot Length (cm)' in the size guide refers to the actual measurement of your foot. The 'CM' size often found on shoe boxes or labels may refer to the internal shoe length, which is typically longer than the foot length to allow for comfort and movement. Always use the 'Foot Length' chart for accurate sizing.

The primary color is Cloud White, with Core Black accents.

Refer to the detailed size guide and measure your foot length. If your measurement falls between two sizes, select the larger size for a more comfortable fit, as recommended. Allow for a slight break-in period.

The knit upper is designed to be adaptive. For a tighter feel, ensure your foot is fully inserted. For a looser feel, check that you haven't overstretched the material. Consider trying a different size if the issue persists after the break-in period.

Boost technology is designed for long-term durability, but cushioning can feel less pronounced with heavy use over time. Ensure the shoes are clean and dry, as dirt can affect performance. If significant degradation occurs, it may be time to consider replacement.
