Saucony Endorphin Pro 4 - Black - UK 11

It is designed for competitive runners of all levels who are looking for maximum speed and efficiency on race day, from 5K to marathon distances. It's best suited for those with a neutral gait.

While technically possible, it's not recommended as its primary use. The Endorphin Pro 4 is a specialized race shoe built for performance and may not offer the same comfort or durability for high-mileage daily training as dedicated trainers. Using it sparingly for races and key fast workouts will extend its lifespan.

The full-length S-shaped carbon fiber plate provides stiffness and acts as a lever to propel you forward. It works with the SPEEDROLL geometry and PWRRUN PB foam to create a more efficient and powerful toe-off, saving energy and increasing speed.

The Endorphin Pro 4 has an 8mm drop (heel-to-toe offset) and weighs approximately 212 grams (for a men's UK size 8 or US size 9).

It's generally recommended to stick with your standard running shoe size. However, given its race-day focus, some runners prefer a slightly snugger fit. If possible, try them on to ensure a comfortable and secure fit, especially around the midfoot and heel.

Yes, the XT-900 outsole provides high traction and durability on typical road surfaces. While it performs well in dry conditions, it also offers reliable grip on slightly wet pavement due to its engineered tread pattern.

The midsole features PWRRUN HG closest to the foot for immediate responsiveness and PWRRUN PB underneath for powerful cushioning and energy return. This combination ensures both a soft landing and an explosive push-off, optimizing stride efficiency.

SPEEDROLL technology is Saucony's signature aggressive sole geometry. It's designed to provide a continuous feeling of momentum, quickly rolling your foot through your gait cycle from landing to toe-off. This helps reduce effort at higher speeds and promotes a more efficient stride.

Check your lacing. The elastic laces allow for a customized fit; try loosening them slightly or re-lacing to alleviate pressure points. Ensure your socks are thin and breathable, suitable for performance running shoes.

This is expected. The Endorphin Pro 4 features a high stack height (39.5mm) and a stiff carbon plate, which provides a unique, propulsive feel. It is designed for speed and efficiency, not plush comfort for everyday mileage. Give yourself a few short, fast runs to adapt.

Ensure your running form utilizes the shoe's SPEEDROLL technology by focusing on a quick, midfoot strike and a forward lean. The propulsion is most evident at higher speeds. Also, confirm the shoes are correctly sized for you; an ill-fitting shoe can hinder performance.

The XT-900 outsole is durable for road use. Excessive wear might indicate using the shoes on abrasive surfaces (like gravel or trails) or a specific gait pattern. These shoes are not designed for daily training mileage; reserving them for races and key workouts will extend their life.

The upper is made of a breathable mesh. Ensure you're wearing appropriate moisture-wicking socks. If the issue persists, consider trying a different lacing pattern to increase airflow around the top of the foot.
