Men's running shoes Saucony Endorphin Speed 5 are light, fast, and incredibly versatile road running shoes designed for runners who want to raise their tempo during fast workouts, intervals, and races. The combination of a responsive foam PWRRUN PB, a redesigned full-length nylon plate, and SPEEDROLL technology provides an explosive yet comfortable running feel.
Endorphin Speed 5 is an excellent bridge between a traditional training shoe and more aggressive carbon-plated racing models. Instead of carbon, it uses a full-length lightweight nylon plate placed between two layers of PWRRUN PB foam. This construction provides extra propulsion and responsiveness but is more adaptable and versatile for everyday faster training.
The light and responsive PWRRUN PB foam offers high energy return and helps maintain a fast, lively stride. With 36 mm foam under the heel and 28 mm under the forefoot, it provides enough cushioning even for longer tempo runs and road races.
The SPEEDROLL technology encourages a smooth forward foot movement and enables a quick transition from landing to propulsion. Endorphin Speed 5 thus shines when a runner increases speed and wants to maintain an efficient rhythm.
The heel features increased coverage of the outsole, improving durability in the most stressed areas. A new longitudinal groove running the full length of the outsole enables a more natural foot cycle and a smoother transition through the running gait.
The upper, made from the new lightweight Engineered Mesh fabric, provides breathability, comfort, and a secure grip on the foot without adding unnecessary weight to the shoes.
The men's version weighs approximately 237 g, with a 8 mm heel-to-toe drop. Due to the light weight, PWRRUN PB foam, and nylon plate, Endorphin Speed 5 is an excellent choice for both fast workouts and runners who want to use one capable model for competitions.

PWRRUN PB is Saucony’s light foam designed for high energy return and a fast feel.
Endorphin Speed 5 uses two layers of responsive PWRRUN PB foam, between which is placed a nylon plate. This construction combines cushioning and propulsion, enabling an efficient running stride at higher speeds.
PWRRUN PB provides enough comfort even for longer training sessions, so Endorphin Speed 5 is not limited to short and fast intervals.
Between the two layers of PWRRUN PB foam is placed a full-length nylon plate.
The plate helps create a faster and more explosive push-off, but is more adaptable than a classic carbon plate.
Thus Endorphin Speed 5 is highly versatile – fast enough for racing, yet more comfortable and adaptable for regular fast training.
The SPEEDROLL technology is designed to encourage forward propulsion and enable more efficient transitions through the running gait.
The shoe geometry together with PWRRUN PB foam and the nylon plate creates a sensation of smooth movement from landing to propulsion.
The combination of full-length nylon plate and two layers of PWRRUN PB foam creates Saucony’s concept of a responsive or “Snappy Ride” feel.
The result is a good balance of cushioning, flexibility, and propulsion, especially noticeable in tempo runs and intervals.
The new longitudinal groove along the full length of the outsole allows more natural foot movement.
The construction improves the transition from landing to propulsion and helps create a smoother running stride even at higher speeds.
The outsole is additionally protected at the heel with greater rubber coverage.
This increases durability of the most stressed area and allows Endorphin Speed 5 to better endure regular use in fast training.
The new lightweight Engineered Mesh upper provides breathability and a comfortable fit without unnecessary weight.
The upper is designed for faster runs while also providing enough comfort for longer training and daily use.
