Nike Air Max 1 '86 OG Obsidian Trainers - Size UK 4

'OG' stands for 'Original,' referring to a reissue of the initial design. 'Obsidian' is the colorway name, indicating the primary navy blue color, accented with white and grey.

While they feature Nike's Air technology for comfort and have a durable outsole for traction, these are primarily lifestyle trainers designed for casual wear and everyday comfort, not for high-performance athletic activities.

Purchase from authorized Nike retailers or reputable sellers. The product description confirms 100% authenticity and includes the original box (OG all), which are good indicators.

Gently wipe the leather with a damp cloth and mild soap. Use a soft brush for the mesh. Avoid harsh chemicals or machine washing. Always air dry.

Yes, the insoles are typically removable, allowing you to replace them with your preferred orthotics or supportive insoles if needed.

Nike generally offers a limited warranty on manufacturing defects. Please refer to Nike's official website or the retailer's policy for specific warranty details applicable to your purchase.

As a retro reissue, sizing can sometimes vary from modern versions. It's advisable to check reviews or consult a size chart, and if possible, try them on before purchasing.

Ensure you have chosen the correct UK size. Consider wearing them for short periods initially to allow the materials to break in. If still uncomfortable, check if they are available in half sizes or a different width if applicable.

Check the lace material and condition. Ensure they are not frayed. Try a different lacing technique or knot. Replace laces if they are worn out.

The visible Air unit is designed for cushioning, not for being fully inflated like a balloon. Minor compression is normal. If there is a significant rupture or leak (e.g., squeaking sounds), this may indicate damage and the shoes should be inspected by a retailer.

Darker colored footwear, especially when new, can sometimes transfer dye. This is more common in damp conditions. Wash the inside of the shoes gently and allow them to dry completely. Wear darker socks initially if color transfer is a concern.
