Saucony - Endorphin Speed 5 - Trainers - Cream - UK 9.5

The Endorphin Speed 5 is primarily designed for fast running, including speed days, track workouts, and races. However, its versatile cushioning and technology also make it suitable for moderate training runs.

The winged nylon plate provides torsional rigidity for stability and a propulsive feel without sacrificing forefoot flexibility. It works with the cushioning to create snappy transitions and an energetic ride.

SPEEDROLL Technology is Saucony's design that creates a feeling of effortless forward momentum, helping you roll through your stride and maintain pace with less perceived effort.

The shoe features PWRRUN PB cushioning, known for its responsiveness and energy return. The stack height is 36mm in the heel and 28mm in the forefoot, with an 8mm offset.

Yes, while optimized for speed, many runners find the Endorphin Speed 5's cushioning and energy return suitable for marathon distances, especially if they are looking for a faster, more responsive feel.

The newly designed mesh is lightweight and breathable, offering comfort and support during fast-paced efforts. It helps keep your feet cool and secure.

The men's size 9.5 (as specified in the product info) weighs approximately 8.4oz (238g).

Adjust the lacing pattern. Consider using a runner's knot for a more secure midfoot fit or skipping eyelets if there's pressure on the top of the foot. Ensure you are wearing appropriate running socks.

While the PWRRUN PB foam is durable, its responsiveness may gradually decrease with very high mileage. Ensure the shoes are used for their intended purpose (running) and not for casual wear to prolong their performance life.

This can sometimes occur due to moisture trapped in the shoe or friction between components. Try ensuring the shoes are completely dry. If the noise persists and is bothersome, it may be a manufacturing anomaly.

The winged nylon plate and SPEEDROLL technology provide a specific feel. If discomfort persists after several runs (a typical break-in period), consider if the shoe's geometry is compatible with your foot strike and biomechanics. Consult with a running specialist if issues continue.
