Nike Air Max 90 - Trainers - Beige - Size 6.5

While inspired by early '90s running shoes, the Air Max 90 is primarily designed as a lifestyle and casual wear shoe. For serious athletic training, dedicated running shoes are recommended.

Refer to Nike's official sizing guide and measure your foot length. It is also advisable to try them on in person if possible, as fit can be subjective and vary slightly between models.

The construction typically involves a woven upper with synthetic overlays, a foam midsole, and a rubber outsole. Specific material compositions may vary slightly by release.

It is not recommended to machine wash your trainers. The harsh cycle and detergents can damage the materials, adhesives, and cushioning systems. Hand washing is the preferred method.

Each Air Max model features Nike's visible Air cushioning technology, but they differ in design, the specific implementation of the Air unit (size, placement, technology), and overall aesthetic, catering to different styles and eras.

The Waffle outsole is known for its durability and provides good traction for everyday use. However, like all rubber outsoles, wear will occur over time with consistent use.

This can sometimes occur due to moisture between layers. Try ensuring the shoes are completely dry. If persistent, a small amount of talcum powder under the insole might help.

Ensure you have the correct size. If the issue persists, break-in periods can vary. Try wearing them for shorter durations initially and consider if thicker or thinner socks make a difference.

The Air unit is designed for cushioning and impact. If you suspect a leak or significant damage, it is recommended to discontinue use and consult Nike's warranty information or a footwear professional.
