Saucony Endorphin Pro 4 - White/Mutant - UK 9.5

The Endorphin Pro 4 is primarily designed for competitive racing, fast tempo runs, and intense interval training on asphalt or road surfaces. It's built for speed and efficiency.

While technically possible, the Endorphin Pro 4 is optimized for performance and speed. For daily training and longer, slower runs, you might prefer a shoe with more traditional cushioning and durability.

PWRRUN HG is a premium foam layer designed for maximum energy return, providing a 'fresh legs' feel. PWRRUN PB is a lighter, bouncy foam made with engineered beads, offering excellent cushioning and speed in a lightweight package. Together, they create a dynamic cushioning system.

The carbon fiber plate adds longitudinal stiffness to the shoe. This rigidity reduces energy loss, enhances propulsion, and promotes a snappy, responsive toe-off, helping you maintain speed and efficiency.

Speedroll Technology is a unique geometry that combines an elevated cushioning and a stiff forefoot, creating an instantly responsive ride that propels you forward. It encourages quicker turnover and a feeling of continuous momentum.

The Saucony Endorphin Pro 4 has an 8mm heel-to-toe offset (39.5mm heel / 31.5mm forefoot), which is a common drop for performance running shoes, facilitating a forward-leaning stride.

Yes, this model is designed with sustainability in mind. It is vegan-friendly and contains a percentage of recycled materials in its construction.

Gently clean the knit and mesh uppers with a soft brush or cloth, using mild soap and cold water. Always air dry the shoes away from direct sunlight or heat, and avoid machine washing or drying.

Check your lacing for tightness or pressure points. Experiment with different lacing patterns. Ensure your socks are appropriate running socks that wick moisture and prevent friction. Confirm you have the correct shoe size and width.

All running shoe cushioning has a lifespan. If you've accumulated significant mileage (typically 300-500 miles for performance shoes), the foams may have compressed. Consider if it's time for a new pair. Also, ensure shoes are properly aired out and dried between runs.

Squeaking can be caused by moisture trapped between the insole and midsole, or between parts of the outsole. Remove the insole and allow both the insole and shoe interior to dry thoroughly. Check for any small debris stuck in the outsole grooves.

While the XT-900 carbon rubber offers good traction, extremely wet or slick surfaces can challenge any outsole. Adjust your stride and pace in such conditions. Ensure the outsole is clean and free of mud or debris that could reduce grip.

Inspect your foot shape and running form; sometimes foot movement or pressure points can cause localized wear. Ensure laces are not tied too tightly across specific areas. Keep shoes clean from abrasive dirt, which can damage the delicate mesh.
