The sizing is generally consistent with other adidas adult trainers. It's recommended to consult the adidas size chart for precise measurements if you are unsure.

It is not recommended to machine wash these trainers, as it can damage the materials and affect the Boost midsole. Hand washing is the preferred method for cleaning.

Different UltraBoost models often feature updates in knit patterns, midsole compounds, outsole designs, and sustainability initiatives. The 4.0 DNA represents a specific iteration focusing on the classic silhouette with modern materials.

The Primeknit upper is designed to stretch slightly with wear. Try wearing them with thicker socks initially or for shorter periods to allow them to adapt to your foot shape.

Ensure the rubber outsole is clean from excessive dirt or debris. Minor wear on the tread is normal, but significant loss of grip may indicate the outsole is worn out.

While Boost cushioning is durable, its responsiveness may decrease slightly after extensive use. Regular cleaning and avoiding extreme conditions can help prolong its performance.
