Nitro Wave trainers - EA7 - Blue

The midsole uses a special foam infused with nitrogen gas, which makes it exceptionally light and bouncy, providing high energy return and shock absorption with less weight.

While they offer excellent responsiveness and cushioning, their ultra-lightweight design is generally better suited for shorter to mid-distance runs and training. For ultra-marathons, a shoe with more structured support and durability might be preferable.

Ensure there is about a thumb's width of space between your longest toe and the end of the shoe when standing. The heel should feel secure without slipping, and the midfoot should feel comfortably snug.

It is not recommended to machine wash the Nitro Wave trainers. Handwashing with a damp cloth and mild soap is the preferred method to preserve the integrity of the materials and technology.

The Nitro Wave series is distinguished by its specific use of nitrogen technology in the midsole, focusing on extreme lightness and responsiveness, differentiating it from models with different cushioning or support systems.

Generally, running shoes should be replaced every 300-500 miles (500-800 km) or when you notice significant wear on the outsole or a loss of cushioning and support. For the Nitro Wave, monitor the midsole's responsiveness and the upper's condition.

This is normal due to the ultra-lightweight and responsive nature of the nitrogen midsole. Wear the shoes for short periods initially and gradually increase duration to allow your feet to adapt.

Ensure the shoes are clean and dry. Excessive moisture or dirt can affect midsole performance. For significant degradation, consider replacing the shoes after extensive use.

The thin, lightweight fabric is intentional for breathability and minimal weight. If a more robust upper is desired, this model might not be the best fit. Ensure no sharp objects have caused damage.
