Saucony Endorphin Speed 5 Trainers - White - Size UK 3

The Endorphin Speed 5 features a nylon plate, which offers a more forgiving and flexible ride compared to the stiffer, more aggressive propulsion typically provided by a carbon fiber plate. This makes it suitable for a wider range of runners and paces.

Yes, the Endorphin Speed 5 is very capable for marathon racing, especially for runners who prefer a more flexible feel or are looking for a faster training shoe that can double as a race day option. Its SPEEDROLL technology and responsive cushioning aid in maintaining pace over long distances.

If you prioritize speed, enjoy fast-paced training sessions like intervals and tempo runs, or are looking for a versatile shoe for race day, the Endorphin Speed 5 is likely a great choice. If your primary need is maximum cushioning for slow, easy miles, other models might be more suitable.

The shoe weighs approximately 8.4oz (238g) for a men's size 9.

The heel-to-toe drop is 8mm.

The nylon plate is designed to be durable and provide consistent flexibility and responsiveness over many miles. Combined with enhanced rubber coverage on the outsole, the shoe offers good overall durability for its performance-oriented design.

The mesh upper is designed for a secure, breathable fit. While not specifically a wide-fit model, the breathable mesh can offer some adaptability. However, runners with significantly wide feet might find it snug during longer efforts.

Ensure laces are not tied too tightly. If the issue persists, consider trying a half-size up, as fit can vary slightly between individuals.

Check for debris in the midsole or outsole grooves. Excessive dirt can affect performance. Ensure the shoe is clean and dry.

While designed for speed, the cushioning might feel firm for extended easy runs. Consider alternating with a more cushioned shoe for recovery days.
