A Look At The Saucony Endorphin Range Author: Dr Brenton Gray Date Posted: 2 July 2025 Let's take a look at the Saucony Endorphin Range, how they differ and how they are intended to be used. If you’re trying to find the right shoe for race day or training runs, we can help you find the Saucony Endorphin that best suits you! PWRRUN PB First off, what's PWRRUN PB? This is made from a special type of PEBA (poly ether block amide) foam. It makes the shoe in general a lot lighter and really responsive and takes it up to a 88% energy return. Even with it being as lightweight as it is, they still have durability through their soles and will keep up on performance, regardless of weather. Endorphin Trainer The Endorphin Trainer is the everyday runner in the Endorphin range. If you’re looking for a consistent long run shoe that will carry you through all your KMs, this is the shoe to add into your rotation. With a focus on PWRRUN cushioning for plush comfort and a durable, responsive design, the Trainer is made to handle those daily KMs without feeling worn out or losing any responsiveness. It’s got a supportive, stable feel that makes it ideal for recovery runs or those easy/long runs that help build endurance over time. The Trainer’s combination of soft cushioning and reliable responsiveness gives you a smooth, comfortable ride day after day, without compromising on that signature Endorphin speed. Endorphin Speed 5 The Saucony Endorphin Speed 5 continues to be the go-to option for runners who crave a balance between speed and comfort. With a sleek, responsive design, it’s perfect for athletes looking for a versatile shoe that can handle both training and race-day efforts. The Speedroll technology gives it a unique rolling sensation, propelling you forward with each stride. Plus, the PWRRUN PB cushioning offers a perfect mix of lightness and softness, giving your legs a break during long runs while maintaining that sharp, quick-feeling responsiveness when you pick up the pace. Whether you’re working on tempo runs or picking up the pace in intervals, the Speed 5 is your trusty partner for every workout. Endorphin Pro 4 The Endorphin Pro 4 is Saucony’s premium race-day shoe, engineered for runners aiming to chase down PRs. With the Carbitex carbon plate and the PWRRUN PB foam, it’s built to deliver explosive speed while maintaining a surprisingly plush feel underfoot. The midsole is made to maximize energy return, and the carbon plate provides that snappy, propulsive feel that can push you forward, helping you find a second wind during your hardest efforts. It’s the perfect shoe for marathons, half-marathons, or any race you are wanting to bring your A game and pull out the big PRs. Endorphin Elite 2 The Endorphin Elite 2 is a high-performance beast designed for the serious competitor looking for every possible advantage. Combining Saucony’s top-tier PWRRUN PB foam with a full-length carbon plate, it offers maximum responsiveness and energy return. This shoe’s hefty aggressive profile gives you that speed-first feel, helping you maintain an efficient stride at top speeds without sacrificing comfort. If you're looking for a podium finish or just aiming to shave seconds off your best time, the Elite 2 is what you’re looking for! It’s got absolutely everything if you’re searching out that top of the line super race shoe.
