Saucony Endorphin Pro 4 - White - UK 13

The Endorphin Pro 4 is specifically designed for high-performance running, including race days, tempo runs, and speed workouts where maximum efficiency and propulsion are desired.

The full carbon plate provides longitudinal stiffness, working with the foam to create a lever effect that propels you forward. This enhances energy return and increases propulsion, helping you maintain faster paces with less effort.

Speedroll Technology is Saucony's signature geometry that creates a stiff forefoot and an elevated cushion, which combine to encourage a continuous rolling motion, helping you move forward with momentum and efficiency.

While you can use them for some faster training sessions, the Endorphin Pro 4 is optimized for performance and racing. For everyday, high-mileage training, a more durable and cushioned daily trainer might be a better choice to preserve the lifespan of your Pro 4s.

The Endorphin Pro 4 uses standard UK sizing. We recommend trying them on, preferably at the end of the day when your feet are slightly swollen, and ensuring there's about a thumb's width of space between your longest toe and the end of the shoe.

The Endorphin Pro 4 is designed for neutral runners. If you have significant overpronation or supination, you might consider shoes with more stability features, though many neutral shoes work well for a variety of foot types.

PWRRUN PB is a PEBA-based foam known for its exceptional lightness, softness, and energy return. PWRRUN HG is a newer, even more energetic foam that provides a snappier, more propulsive feel. The fusion in the Endorphin Pro 4 combines the best attributes of both for an optimal ride.

Ensure you are lacing your shoes correctly for a secure fit without over-tightening. Experiment with different lacing patterns if needed. Ensure you are wearing appropriate running socks designed to wick moisture and prevent friction. Allow for a short break-in period if the shoes are new.

Performance running shoes, especially those with advanced foam and carbon plates, have a limited effective lifespan. This feeling often indicates that the midsole cushioning or carbon plate has lost some of its integrity. Consider checking your mileage; it might be time to replace your shoes. Also, ensure they are clean, as dirt can affect flexibility.

Inspect the outsole for wear. If the treads are significantly worn down, especially in high-contact areas, the shoe's grip will be compromised. Also, ensure the outsole is clean of debris, mud, or oil that could reduce traction. For very wet conditions, no shoe can guarantee absolute grip.
