Nike Air Max Plus 7 Trainers - Smoke Grey/ Metallic Silver-Iron Grey - UK 11

The Nike Air Max Plus 7 trainers are designed for everyday wear and light athletic activities, offering good cushioning. For marathon running, specialized running shoes with advanced support and cushioning systems are generally recommended.

It is recommended to try the trainers on if possible, as sizing can vary slightly. You can also compare with a Nike size chart. For this specific model, it is listed in UK men's sizes.

No, machine washing is not recommended as it can damage the materials and the Air Max cushioning system. Clean them by hand using a soft brush or cloth and mild soap.

The Air Max technology features encapsulated air in the midsole, providing superior cushioning and shock absorption to reduce impact on your feet and joints.

These trainers typically feature a combination of synthetic leather, mesh, and durable rubber for the sole, designed for both comfort and longevity.

Store your trainers in a cool, dry place, away from direct sunlight and heat. Using shoe trees can help maintain their shape.

This can sometimes occur with new shoes. Try wearing them for a few days to break them in. If it persists, check for any debris trapped in the sole or ensure the insoles are properly seated.

Ensure you have the correct size. If the issue persists with the correct size, consider using thicker or thinner socks, or ensure the laces are adjusted properly to avoid over-tightening.

New shoe soles can sometimes have a coating that reduces grip. Lightly scuffing the soles on a rough surface or wearing them in for a short period can improve traction. Ensure the surfaces you are walking on are not wet or oily.
