Nike Air Zoom Pegasus 39 NN GS Trainers - Blue/Red - UK 5.5

The Pegasus 39 NN GS features an engineered mesh upper that offers some flexibility. However, they are generally designed for a standard width foot. If you have particularly wide feet, it's recommended to try them on or consult sizing guides carefully.

You should have 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 there should be no pinching or excessive tightness across the width of your foot.

While versatile for running, their design is optimized for the forward motion of running. For lateral movements in sports like basketball or tennis, dedicated shoes for those activities would provide better support and stability.

Version 39 features updated engineered mesh for improved breathability and flexibility, dual Zoom Air units (forefoot and heel) for enhanced energy return, and an optimized heel shape for smoother transitions.

React foam is known for its durability and resilience, providing consistent cushioning over many miles, making it suitable for daily training.

The engineered mesh offers some breathability but is not waterproof. They can handle light moisture, but prolonged exposure to heavy rain may lead to wet feet. They are best suited for dry or mildly damp conditions.

Ensure the laces are threaded through all eyelets and tied with a secure knot. Consider using a runner's loop for extra lockdown if needed.

Verify that the laces are not tied too tightly, which can restrict airflow. Ensure the socks worn are also breathable.

While durable, the Zoom Air units and foam may gradually reduce in responsiveness with extensive mileage. Regular cleaning and proper storage can help maintain performance.
