Nike Air Max BIA Trainers - Blue - Size 11.5

No, the Nike Air Max BIA trainers are designed for everyday wear and light athletic activities. For marathon running, specialized performance running shoes are recommended.

The product lists UK sizing directly. Ensure your foot measurement corresponds accurately to the Nike sizing chart, with this specific model being a UK 11.5.

It is not recommended to machine wash these trainers, as it can damage the materials and the Air Max cushioning. Hand washing with mild soap and water is the preferred method.

The Air Max cushioning provides excellent impact absorption, reducing stress on your feet and joints during wear.

Store them in a cool, dry place, away from direct sunlight and heat, to maintain their material integrity and colour.

While this guide focuses on the Midnight Navy and Obsidian Sail colourway, the Air Max BIA series is available in other colour combinations as listed in the product variants.

The trainers may require a brief break-in period. Wear them for short durations initially and gradually increase wear time as they conform to your foot.

Some creasing is normal with use and does not typically affect performance or comfort. To minimize, ensure proper fit and avoid over-tightening laces.

While durable, cushioning can naturally diminish with extensive use. Regular cleaning and proper care can help preserve the feel. Consider replacing if the cushioning is no longer adequate for your needs.
