Saucony - Endorphin Speed 5 Trainers - Cream - UK 11.5

The nylon plate is designed to provide a propulsive feel and work with the foam to create snappy transitions, helping you run faster and more efficiently.

Yes, the shoe's speed-focused design and responsive cushioning make it a good option for marathon racing, especially for runners who prefer a slightly firmer, more connected feel.

PWRRUN PB is Saucony's lightest and most responsive PEBA-based foam, offering excellent energy return and a lively feel compared to more traditional EVA foams.

While comfortable, the Endorphin Speed 5 is engineered for performance running. For everyday wear, a shoe with a softer, more forgiving midsole might be preferable.

For optimal performance, most running shoes, including the Endorphin Speed 5, are recommended to be replaced every 300-500 miles, depending on running surface, intensity, and individual biomechanics.

The Endorphin Speed 5 generally runs true to size for most runners. It aims for a secure midfoot lockdown with ample room in the toe box for splay.

Ensure you have the correct UK size. If the issue persists, try adjusting the lacing pattern to alleviate pressure points. For a wider fit, consider if a different model or brand might be more suitable.

Check for any debris or blockages in the outsole or between the cushioning and plate. Ensure the shoe has dried completely after wet runs. High mileage can naturally reduce cushioning responsiveness.

Allow a break-in period of a few runs. The engineered mesh and plate may require some time to mold to your foot's shape and your running gait.
