Measure your foot length from heel to the longest toe. Compare this measurement to the EU size chart provided in the product description. If your measurement falls between two sizes, it is recommended to choose the larger size. Remember that the CM size on the shoebox may not directly correspond to foot length in centimeters.

The Nike Air Max Bia Viva Trainers are designed for general training and casual wear. While they offer good cushioning, they are not specialized for marathon running, which may require shoes with specific features for long-distance performance and support.

The Air Max unit is Nike's signature cushioning technology. Its primary benefit is to provide excellent shock absorption and responsive comfort, reducing impact on your feet and joints during movement.

No, machine washing is not recommended as it can damage the materials and structure of the shoe. It is best to clean them by hand using a damp cloth and air dry them.

The specific materials include a breathable upper designed for airflow and durable components for longevity. The sole features the responsive Air Max cushioning unit.
