Saucony - Endorphin Speed 5 - Trainers - White - Blue - Size UK 10

The newly designed nylon plate enhances snappy transitions and provides a propulsive feel, helping you run faster with more efficiency.

The Endorphin Speed 5 is versatile and excels in faster training paces like tempo runs and intervals, and is also a capable race day shoe for distances up to a half marathon.

PWRRUN PB cushioning is lightweight and highly responsive, offering excellent energy return to make your faster runs feel more dynamic and less fatiguing.

It's best for adult female runners who want a shoe to help them pick up the pace, whether for track workouts, tempo runs, or chasing personal records.

Gently wipe the exterior with a damp cloth. For a deeper clean, use mild soap and water with a soft brush, then air dry away from direct heat. Avoid machine washing.

While they can be used for longer runs, they are optimized for faster paces. For very slow or recovery runs, a shoe with a softer, more forgiving ride might be more comfortable.

These trainers are primarily designed for road running and can also be used effectively on track surfaces.

Allow for a break-in period of 10-20 miles. Adjust lacing techniques to relieve pressure points. Ensure you are wearing appropriate running socks.

Ensure you are running at a pace that engages the nylon plate. This shoe performs best at faster speeds (tempo pace and above). Check that the cushioning hasn't compressed significantly due to extensive use.

While designed for good grip, performance on very wet or slick surfaces can vary. Clean the outsole regularly to remove debris that could impede traction. Consider alternative shoes for extremely wet conditions.

Re-lace the shoes, ensuring the midfoot is secured properly. Experiment with different lacing patterns. If the issue persists, the shoe may not be the right fit for your foot shape.
