Saucony Endorphin Speed 5 - White/Red - UK 11

The Endorphin Speed 5 is optimized for faster running with its SPEEDROLL technology, PWRRUN PB foam, and nylon plate, offering more responsiveness. Daily trainers typically prioritize comfort and cushioning for longer, slower runs.

Yes, the Endorphin Speed 5 is suitable for marathon racing, especially for runners who prefer a responsive and propulsive feel. For those seeking maximum cushioning or a more aggressive ride, other models might be considered.

Neutral support is suitable for runners whose feet do not excessively roll inward (pronate) or outward (supinate) during their stride. If you're unsure, consult a running shoe specialist or observe your wear patterns on old shoes.

The shoe weighs approximately 8.4oz (238g) for a men's size 9, and it has a heel-to-toe drop of 8mm (36mm in the heel and 28mm in the forefoot).

Generally, a nylon plate is more flexible than a carbon plate. It provides a snappy and propulsive feel while maintaining some forefoot flexibility, whereas carbon plates are typically stiffer and designed for maximum propulsion.

The Endorphin Speed 5 features an optimized outsole with increased rubber coverage on the heel, which enhances durability for regular training and racing use.

Adjust the lacing system. Try different lacing techniques to find a secure but not constrictive fit. Ensure you are wearing appropriate running socks.

This can occur after significant mileage. While the PWRRUN PB foam is durable, its responsiveness will naturally decrease with wear. Consider when the shoes were purchased and their total mileage.

The outsole provides good grip on dry surfaces. On very wet or slick surfaces, reduce speed and exercise caution, as with any running shoe.
