Saucony Endorphin Pro 4 Competition Running Shoe - Blue - Size 13

The Endorphin Pro 4 is primarily designed as a competition running shoe, specifically engineered for speed, efficiency, and achieving personal bests in races like marathons and half-marathons.

The S-shaped carbon fiber plate acts as a stiffening element within the midsole, providing a propulsive springboard effect. This, combined with SPEEDROLL technology, creates a rigid lever that promotes an energetic and steady forward push, helping you maintain speed with less effort.

SPEEDROLL Technology is Saucony's geometry that optimizes your running technique. It's an elevated cushioning and a stiff forefoot that encourages a smooth, fast transition from landing to toe-off, placing your foot exactly under your body's center of gravity for maximum propulsion.

The Saucony Endorphin Pro 4 features a substantial stack height of 39.5 mm and has an 8mm heel-to-toe drop.

This model weighs approximately 212 grams (for a men's size US 9, exact weight varies by size).

While you can use them for occasional speed workouts, the Endorphin Pro 4 is optimized for racing. Using them for all your daily training runs may shorten their lifespan and you might miss out on the benefits of a more cushioned, durable daily trainer.

Saucony generally aims for consistent sizing across its range. However, due to its performance fit and materials, it's always recommended to try on the shoes or consult a size chart, especially if you are between sizes or new to the brand. This specific variant is a UK Size 13.

Ensure you have the correct size and width. Experiment with different lacing techniques to relieve pressure points. Wear appropriate running socks designed to prevent friction. If the issue persists, gradually break in the shoes on shorter runs.

The Endorphin Pro 4 is designed for forward propulsion on even surfaces. Its high stack height and carbon plate prioritize speed over maximal stability. Focus on good running form. If instability is a significant concern, these shoes might not be ideal for technical trails or very uneven ground.

Ensure you are using a secure lacing knot, such as a double knot. The elastic laces are designed for flexibility, but a firm knot is still essential. You can also try alternative lacing patterns for a more secure fit.

All running shoes have a lifespan. The responsiveness of the PWRRUN PB foam and carbon plate will diminish after significant mileage (typically 200-400 miles for racing shoes). Track your mileage and consider replacing the shoes when they no longer feel as dynamic.

Squeaking can sometimes occur due to friction between parts of the shoe or between the shoe and your sock/insole. Check if the insole is properly seated. If the squeaking persists, it might be an internal material issue, but often resolves itself after a few runs.
