Saucony Endorphin Pro 4 - Mint, 6.5

While it can be used for some faster training sessions, the Endorphin Pro 4 is primarily designed as a high-performance racing shoe. Its aggressive geometry and carbon plate are optimized for speed, so using it as an everyday trainer might reduce its lifespan and be less comfortable for slower paces.

The S-shaped carbon fiber plate provides stiffness and acts like a lever, propelling you forward. It works with the SPEEDROLL technology and PWRRUN PB foam to create a highly efficient and energetic ride, helping maintain speed and reduce fatigue over long distances.

The Endorphin Pro 4 features a significant stack height of 39.5mm, providing ample cushioning. It has an 8mm heel-to-toe drop, which is a common and versatile drop for many runners.

Gently clean the upper with a damp cloth and mild soap. Avoid machine washing or using harsh detergents. Air dry them at room temperature, away from direct heat or sunlight.

This shoe excels in races of all distances (from 5K to marathon), tempo runs, and interval training where you aim to achieve peak performance and fast splits.

Info needed: Typically, high-performance racing shoes like the Endorphin Pro 4 are offered in a standard width to ensure a snug, performance fit. Please check specific product listings for available width options.

This can be normal for a carbon-plated racing shoe. Gradually increase wear time on speed workouts. If discomfort persists, ensure proper sizing and lacing, and consider if the shoe's aggressive geometry suits your foot strike.

Ensure you are using a secure lacing knot, such as a double knot. The elastic laces are designed for adaptability, but a firm knot is still required for race conditions.

Check your sock choice; opt for seamless, moisture-wicking running socks. Re-evaluate your lacing to ensure it's snug but not constricting any areas. Ensure the thin tongue is lying flat.
