Saucony Endorphin Azura Trainers - Black - UK 6.5

SpeedRoll technology is designed to create a propulsive feeling, encouraging a smoother and quicker transition from your heel strike to toe-off, helping you run faster with less perceived effort.

Yes, the Endorphin Azura can be used for marathon running due to its cushioning and comfort. However, runners seeking maximum cushioning for very long distances might prefer models with more substantial midsole foam.

PWRRUN PB is a premium, PEBA-based foam that offers exceptional energy return and a lightweight, bouncy feel, distinct from firmer EVA-based foams.

While the XT-900 outsole offers decent grip, these trainers are primarily designed for road running. They may handle very light, groomed trails but are not ideal for technical terrain.

This shoe features responsive foam and SpeedRoll technology for a fast feel, but it does not contain a rigid plate (like carbon fiber). This results in a more natural and flexible ride compared to plated racing shoes.

Refer to the brand's official size guide or try on the shoes in person if possible. Generally, you should have about a thumb's width of space between your longest toe and the end of the shoe.

Adjust the lacing system to find a more comfortable fit. Ensure you are wearing appropriate running socks. If discomfort persists, the shoe size may not be suitable.

The PWRRUN PB foam is designed for longevity, but performance may subtly decrease after significant mileage. Ensure the shoes are clean and that no debris is trapped in the midsole.

The XT-900 rubber provides good traction, but all outsoles have limitations on extremely slick surfaces. Clean the outsole to remove any mud or debris that might be interfering with grip.
