Nike Air Max Flyknit Racer Trainers - Grey/Black - UK 14

The Nike Air Max Flyknit Racer is primarily designed for lifestyle wear and light athletic activities. For marathon running, we recommend specialized running shoes that offer advanced support and cushioning tailored for endurance.

It is best to measure your foot length and compare it with Nike's official sizing chart. If possible, try on a pair in-store to ensure a comfortable fit, as sizing can vary slightly between models.

We do not recommend machine washing the Nike Air Max Flyknit Racer. The Flyknit upper and Air Max unit can be damaged by the harsh cycle. Hand washing with mild soap and water is the preferred method.

The primary advantage of Flyknit is its lightweight, breathable, and adaptive nature, which creates a comfortable, sock-like fit that moves with your foot.

The Air Max unit contains pressurized air within a durable pouch, designed to compress upon impact and provide responsive cushioning to reduce shock on your feet and joints.

The Flyknit upper offers breathability but is not waterproof. While it can handle light moisture, it is not ideal for heavy rain or puddles. Consider using a water-repellent spray specifically designed for sneakers if you plan to wear them in damp conditions.

This can sometimes occur between the sole and the insole. Try removing the insole and cleaning both surfaces, then reinserting it. If the sound persists, it might be due to air pockets within the sole unit, which is rare but can happen.

Wear the shoes with thicker socks for a short period or use a shoe stretcher designed for knit materials. The Flyknit is designed to stretch slightly over time with wear.

While Air Max units are durable, cushioning can lessen with extensive wear. Ensure the shoes are not being used for activities beyond their intended purpose, which can accelerate wear.
