Saucony Endorphin Pro 4 - Grey, Size 4

The Endorphin Pro 4 is best suited for racing and speed workouts, from short distances to marathons. Its design prioritizes propulsion, efficiency, and speed over high-mileage daily training.

SPEEDROLL technology is Saucony's geometry that includes an elevated cushioning and a stiff forefoot, creating an instantly responsive ride that feels like continuous momentum. It helps optimize your running technique by guiding your foot to land under your center of gravity.

While durable enough for occasional speed work, the Endorphin Pro 4 is a specialized racing shoe. For everyday training, many runners prefer a more cushioned and less aggressive shoe to preserve the Endorphin Pro 4 for race days and key workouts, thereby extending its peak performance life.

The Saucony Endorphin Pro 4 weighs 212 grams and has an 8mm drop (heel-to-toe offset).

The Endorphin Pro 4 features a significant stack height of 39.5 mm, providing substantial cushioning and a propulsive feel.

Gently brush off loose dirt. Use a mild soap and cold water with a cloth or sponge to clean the upper and outsole. Air dry them at room temperature; do not machine wash or use direct heat.

While you can, the Endorphin Pro 4 is specifically engineered for running performance. Its aggressive geometry, carbon plate, and firm cushioning are not optimized for casual walking, which might feel less comfortable or stable compared to a dedicated lifestyle shoe.

Ensure you are wearing appropriate running socks. Experiment with different lacing techniques; the elastic laces offer flexibility. The thin, adaptable tongue should minimize rubbing, but check for any bunching. If discomfort persists, ensure the shoe size is correct for your foot type.

Racing shoes, especially those with carbon plates and specialized foams, have a performance lifespan. Reduced responsiveness can indicate that the shoe is reaching the end of its effective life for peak performance. Consider using them for lighter training or replacing them for races. Regular cleaning and proper storage can help maintain material integrity.

While the outsole is made of durable material with lots of traction, certain extreme conditions (e.g., very wet, muddy, or icy surfaces) might still pose a challenge. Always be mindful of running surfaces. Check the outsole for excessive wear if traction issues become consistent on typical running surfaces.

The S-shaped carbon fiber plate is designed to provide stiffness for propulsion. If this feels too rigid, it might take a few runs to adapt to the shoe's mechanics. Ensure your running form is aligned with the shoe's SPEEDROLL technology. If discomfort persists, this shoe's aggressive racing profile might not perfectly align with your biomechanics or preference for a softer ride.
