The Saucony Endorphin Pro 4 is a high-performance running shoe engineered for race day that also works well for faster workouts. Equipped with a dual-layer midsole and a full-length carbon fiber plate, it promises a lively, smooth ride that feels efficient and quick on the road. The spacious and breathable upper adds comfort for longer runs, while the well-covered outsole feels durable.
Our Verdict
The Saucony Endorphin Pro 4 is a great choice for marathons, offering a balanced combination of low weight, great energy return, and decent cushioning. It also has good lateral stability, which is rare for a super shoe, making it a good option for longer distances when form starts to break down. However, the foam's firmness can make it feel a bit harsh on the feet after a while.

The Saucony Endorphin Pro 4 is great for shorter-distance racing. Its impressive forefoot firmness and lighter weight provide a responsive and efficient running experience.

The Saucony Endorphin Pro 4 offers impressive responsiveness. The dual-layer PEBA-based foam offers great energy return, feeling just as bouncy for heel strikers as for forefoot strikers. The carbon plate helps the midsole rocker hold its shape under load, contributing to consistent forward roll and snappy toe-offs. The Endorphin Pro 4 is responsive enough to handle both faster training sessions and races.

The Saucony Endorphin Pro 4 provides good lateral stability, particularly due to its wide base and very firm forefoot foam. This is beneficial for maintaining balance and efficiency, especially during longer runs. However, the high stack height makes you feel quite high off the ground, which can affect stability. That said, it has good stability for a super shoe, without significantly compromising other aspects.

Popular Running Shoe Comparisons
The Saucony Endorphin Pro 4 is a well-balanced super shoe that blends speed, cushioning, and stability more seamlessly than many of its competitors. While it's great as a racing shoe, it leans toward the firmer side and isn't the most cushioned option, making it particularly well-suited for shorter distances like 5Ks and 10Ks. That said, it's still a capable marathon option, though not as specialized for long distances as some other super shoes like the Nike Alphafly 3 and the adidas Adizero Adios Pro 4.
This feature combination positions it among shoes in the unofficial 'hyper trainer' category—primarily built for racing but versatile enough to handle track intervals and even uptempo workouts without feeling overly aggressive. If you're searching for another super shoe with good stability but with a softer feel, take a look at the Diadora Gara Carbon 2.
Within Saucony's lineup, the Endorphin Pro 4 sits above the Saucony Triumph 22, a max-cushioned daily trainer, and the Saucony Endorphin Speed 5, a super trainer with a PEBA midsole and nylon plate designed for a mix of training and faster efforts. However, it sits below the Saucony Endorphin Elite 2, Saucony's top-tier, most aggressive racing shoe, which is built purely for absolute performance.

The Nike Alphafly 3 and the Saucony Endorphin Pro 4 are both high-performance racing shoes, but they cater to different types of runners and preferences. The Saucony is stiffer in the forefoot, providing a more structured toe-off. It also offers slightly better lateral stability than the Nike, benefiting runners who need extra support during turns. Additionally, its geometry is particularly well-suited for heel strikers. On the other hand, the Nike shoe is lighter while still delivering better cushioning, maximizing efficiency over long distances. While the Saucony is an excellent option for both racing and versatile enough for workouts, the Nike remains hard to beat for those prioritizing raw speed and performance.
Saucony Endorphin Pro 4 vs adidas Adizero Adios Pro 4
The Nike Vaporfly 4 and the Saucony Endorphin Pro 4 are both carbon-plated super shoes built for race day, but they offer different strengths. The Vaporfly 4 is significantly lighter and geared toward runners prioritizing absolute performance and efficiency, especially over half-marathon distances. The Endorphin Pro 4, while heavier, provides more stability, and it has a firmer forefoot that delivers a snappier toe-off.
The Saucony Endorphin Speed 5 and Saucony Endorphin Pro 4 may share a family, but they serve different purposes within the Endorphin lineup. The Pro 4 is a race-day super shoe built for peak performance with a carbon plate, a higher stack height, and a more propulsive, energetic ride. It's noticeably lighter, more aggressive, and features a snug, performance-oriented fit that's optimized for race conditions. The Speed 5, by contrast, is a plated super trainer. It's slightly lower to the ground and uses a nylon plate instead of carbon, offering more flexibility. The fit is also roomier, making it more comfortable and accommodating for runners who don't want an ultra-tight upper. If you're chasing a personal best and want maximum efficiency on race day, the Endorphin Pro 4 is the clear choice. But for runners who prefer something more approachable that can double for uptempo workouts and racing, the Speed 5 remains a solid alternative with a gentler feel and broader fit.
We buy and test running shoes with a very data-oriented approach. While we're just getting started, our methodology already has dozens of tests to help you make the right purchasing decision for your needs. Not only do we use high-end equipment to gather objective data, but we also order multiple sizes of the same shoes so team members can log in miles. This real-world testing is conducted at various paces and conditions, across different types of workouts, to cover all the bases. This allows us to verify our results and ensure they align with what you might feel with a specific pair.
Test Results
This shoe is lightweight, making it quite efficient and suitable for various racing distances. However, some other super shoes, such as the Nike Vaporfly 4, are way lighter.
This shoe delivers impressive energy return in the heel, providing a responsive feel that enhances the overall running experience. Its design makes it one of the few super shoes that naturally accommodates heel striking.
The forefoot energy return is also great. The foam decompresses rapidly after each foot strike, providing a springy and efficient running experience.
The heel cushioning provides a decent level of protection underfoot, but it's not the most cushioned option available. As the miles add up, you may start to feel the impact from the ground more.
The forefoot cushioning is satisfactory, ensuring a balanced level of comfort for the runner. However, some other super shoes, such as the On Cloudboom Strike, offer significantly more cushioning in the forefoot.
The heel feels firm enough to provide adequate stability and support during runs. However, when higher forces are applied, such as when picking up the pace, the heel starts to feel softer compared to other shoes like the Nike Vaporfly 3.
The forefoot stands out with its impressive firmness, enhancing the shoe's overall stability while also aiding in a dynamic toe-off for a more propulsive stride.
