Nike Air Max 90 - White - Size 4

While the Air Max 90 features Air Max cushioning, they were originally designed for performance running but are now primarily considered a lifestyle shoe. For marathon running, specialized running shoes offering targeted support and cushioning are recommended.

Refer to the Nike sizing chart for women's trainers. It's advisable to measure your foot length and compare it to the chart. Many users suggest trying them on if possible, as fits can vary.

It means that at least 20% of the shoe's weight is made from recycled materials, contributing to Nike's sustainability efforts. This does not typically compromise performance or durability.

The trainers offer some protection, but they are not waterproof. Extended exposure to heavy rain may lead to discomfort and can affect the materials. It's best to avoid wearing them in very wet conditions.

Use a damp cloth with a small amount of mild soap. Gently wipe the leather surfaces. For tougher stains, a specialized leather cleaner can be used, followed by wiping with a clean, damp cloth. Always allow to air dry.

The Air Max 90 is distinguished by its chunky silhouette, segmented midsole, and the specific placement and design of its visible Air unit, embodying a distinct '90s aesthetic compared to sleeker or more modern Air Max designs.

Ensure you have selected the correct size. Consult the sizing chart and consider your foot width. Break-in the shoes by wearing them for short periods initially.

The Waffle outsole provides good traction, but very smooth or wet surfaces can reduce grip. Ensure the outsole is clean from debris, which can affect performance.

The Air unit is designed for cushioning and may naturally compress over time with heavy use. If there is a visible puncture or significant deflation, contact customer support for assessment.

Some creasing is normal with leather and synthetic materials, especially around the toe box, during wear. Proper cleaning and care can help maintain the overall appearance.
