Air Jordan 4 Retro 'Infrared' - Size: 11 UK

The upper is primarily constructed from Durabuck, a type of synthetic nubuck, with black TPU mesh inserts.

Use a soft brush or a slightly damp cloth. Avoid harsh chemicals or soaking the material. Specialized sneaker cleaners for nubuck can be used cautiously.

While they feature cushioning, they are primarily designed as lifestyle sneakers. They can handle light athletic activity, but are not optimized for high-impact sports compared to dedicated performance basketball shoes.

Infrared is a specific color, a vibrant red-orange hue used here as an accent color on elements like the lacing system and tongue label, providing a contrast to the grey upper.

Air Jordan 4s generally run true to size for most individuals. However, slight variations can occur, and trying them on is recommended if possible.

While the Durabuck offers some resilience, it is not waterproof. It's best to avoid wearing them in heavy rain or wet conditions to protect the material.

The visible Air unit in the heel provides enhanced cushioning and impact absorption, contributing to overall comfort during wear.

Gently use a specialized sneaker eraser or a soft brush. For tougher marks, a damp cloth with minimal, mild soap may be used sparingly, followed by careful blotting.

This is a natural aging process for polyurethane. While it cannot be reversed, keeping the shoes out of direct sunlight and cleaning them regularly may slow the process. For some, 'de-yellowing' treatments exist but should be used with extreme caution.

Remove laces and hand-wash them with mild detergent and water. Allow them to air dry completely before re-lacing.

Some creasing is natural with wear. Shoe trees can help minimize creasing when the shoes are not being worn. Avoid overly tight lacing which can exacerbate creasing.
