Saucony Endorphin Pro 4 - Black - UK 13

The Endorphin Pro 4 is specifically designed for long-distance racing, such as marathons and half-marathons, as well as high-intensity training like tempo runs and intervals where speed and efficiency are paramount.

This innovative foam blend provides a dual benefit: `PWRRUN HG` offers maximum energy return for a fast, propulsive feel, while `PWRRUN PB` delivers lightweight, responsive cushioning for sustained comfort throughout long distances.

While durable, the Endorphin Pro 4 is a specialized racing shoe. For optimal longevity and to maximize its performance benefits on race day, it's recommended to reserve them for faster training sessions and races, rather than using them for daily, easy runs.

`Speedroll` technology is Saucony's geometry that creates a stiff forefoot and an elevated cushion, leading to an instant feeling of continuous momentum. It's designed to propel you forward with less effort, making your stride feel smoother and faster.

Running shoe sizing can vary between brands. It's always best to try them on to ensure a comfortable fit. For a performance shoe like the Endorphin Pro 4, you generally want about a thumb's width of space between your longest toe and the end of the shoe.

Yes, the full carbon plate is integral to the shoe's snappy, propulsive feel. You may notice a sensation of being pushed forward, contributing to the shoe's efficient ride. It's designed to work seamlessly with the foam for a powerful stride.

Ensure you have the correct size (UK 13) and that your laces are tied appropriately, not too tight or too loose. Check your socks for seams that might cause friction. Break-in new shoes with shorter runs before a major race.

Performance running shoes have a finite lifespan. This could indicate the foam and carbon plate are losing their elasticity due to accumulated mileage. Consider retiring the shoes or reserving them for shorter, less demanding runs.

Re-evaluate your lacing technique for a more secure midfoot lockdown. Ensure your running socks provide adequate grip and are not too thin or silky. If the issue persists, your foot shape might require an alternative lacing pattern.

Excessive wear can occur if the shoes are used predominantly on abrasive surfaces or if you have a foot strike pattern that causes high friction in specific areas. While designed for durability, these are performance shoes and wear can be faster than daily trainers. Consider rotating them with other shoes.
