Men's Blue Endorphin Speed 4 Trainers

<p>The Saucony Endorphin Speed 4 is built for runners who want the perfect balance of speed, comfort, and everyday performance. Designed to help you push the pace, this shoe combines PWRRUN PB cushioning, a winged nylon plate, and SPEEDROLL technology to deliver effortless speed and energy return—so you can run faster, not harder.</p> <p><strong>Breathable, Secure Upper</strong></p> <p>Designed for lightweight, breathable support, the zonal-engineered mesh upper has been fully updated to deliver a comfortable, race-ready fit from heel to toe. This minimal, perforated mesh keeps the shoe ultra-light while allowing for maximum airflow, so your feet stay cool and dry, even when the tempo picks up. Acting like a second skin, the mesh creates the ideal microclimate for all-day comfort. Plus, FORMFIT technology wraps around your foot for a personalised fit that makes every run feel like these shoes were made just for you. A secure lacing system locks in the midfoot, reducing unwanted movement so you can focus on your stride, not your shoes.</p> <p><strong>Springy Cushioning for Everyday Speed</strong></p> <p>At the heart of the Endorphin Speed 4 is Saucony’s signature PWRRUN PB foam, an ultralight, springy cushioning system that provides a soft, stable base underfoot. Whether you’re tackling daily training runs or pushing for a new PB, this midsole ensures an energy-packed, responsive ride. The updated winged nylon plate brings a balance of speed and support, adding a snappy feel while maintaining flexibility for daily mileage. Working alongside SPEEDROLL technology, the plate helps propel you forward with smooth transitions, giving you that effortless rolling motion that keeps the momentum going. The result? A ride that’s fast, energetic, and adaptable—perfect for speed sessions, long runs, and everything in between.</p> <p><strong>Durable, High-Traction Outsole</strong></p> <p>No matter the surface, the XT-900 outsole ensures exceptional grip and durability. This hardwearing rubber compound forms a strong connection with the ground, providing confidence on wet pavement, compact dirt, and even light track work. Reinforced in high-wear areas, the outsole is built to last, standing up to long-distance training and daily miles. Multi-directional grooves enhance flexibility and efficiency, making takeoffs, landings, and quick changes in direction feel effortless.</p> <p><strong>Why You’ll Love It</strong></p> <p>The Endorphin Speed 4 is your go-to for fast training runs, tempo sessions, and race day alike. With its lightweight build, snappy feel, and smooth rolling transitions, this shoe makes every run feel easier—so you can focus on running faster, not working harder.<span></span></p> <ul> <li>Best for: Everyday Training</li> <li>Heel-to-toe Offset: 8mm (39.5/31.5mm forefoot)</li> <li>Winged Fluted Plate<br> </li> <li>PWRRUN PB Foam</li> <li>SRS Sockliner</li> <li>XT-900 Carbon Rubber Outsole</li> <li>Weight: 8.2oz (233g)</li> <li>This style is vegan and contains recycled materials</li> </ul> <p><span>Model: S20940-68</span></p> Colour: blue
