1. XT-900 Outsole: Provides enhanced road grip.

2. S-Curve Carbon Fiber Plate: Delivers responsiveness and propulsion with every stride.

3. PWRRUN PB Midsole: Saucony's premium cushioning technology that helps you go further. It is soft, responsive, and softer than the foam used in the 1 and 2 models.

Now let's take a closer look at each part to see what technologies are involved and what the  Endorphin Pro 3 looks like up close, and who it is best suited for.

UPPER - Mesh with large ventilation holes

This is a change from the already thin upper of the previous model. The 3 is even thinner and features a fully mesh upper. From trying it on, I immediately felt its comfort and breathability, with cool air flowing through to carry heat away from my feet. What is noteworthy is that the material does not feel as fragile as it looks. It feels slightly stiff, which should make it more durable. (However, I do feel that with this mesh design, if you wear brightly colored socks, the colors often show through.)

The tongue is designed to be lightweight and thin, with a softer edge than the rest of the shoe to prevent ankle irritation. As for the fit issue in the 1 and 2 models, the 3 performs better, offering a more secure and supportive fit.

MIDSOLE - Similar technology, but it feels different

Although the  Endorphin Pro 3 uses the same PWRRUN PB foam, its increased thickness makes it feel less stiff, though not completely. I feel it is more comfortable on the foot than the 1 and 2 models and does not seem to deter new runners who want to try carbon-plated shoes. 

.

And of course, there is another key selling point of the  Endorphin Pro 3: the S-shaped carbon plate hidden in the midsole. This is what gives the shoe its responsiveness and bounce, providing the power to propel the wearer forward. In fact, the excitement and thrill of this shoe do not come from just these two technologies. The Endorphin Pro has won over many runners because of another technology called "Speedroll."

Speedroll technology features a curved design at both the front and back of the shoe, making it feel as though the shoe is constantly propelling you forward while running. On one hand, this makes running feel easier, but on the other, it can be exhausting if you cannot control it. The first time I used it, I felt as though the shoe was constantly whipping me forward, saying, "Go! Run! You can go further and faster! Snap!" That is exactly how it feels, haha. It is ready to roll and push you forward, and this level of pampering makes it easy for many to fall for. (You can feel how much it helps just by walking.) This is not to mention the stiffness of the carbon plate, which some people dislike, though this model is considered less stiff.

OUTSOLE - A racing shoe with exceptionally durable soles

XT-900 is a developed outsole made from premium carbon rubber that provides excellent grip and durability. Having used the 1 model for many months, and even a year, the sole itself is quite durable, remains functional, and does not slip. This is surprising every time, as racing shoes usually do not have very durable soles. What is even better is that the XT-900 rubber covers almost the entire sole, which I think is different from other models, where it is usually only placed around the heel and a small area at the front.

Who is the Saucony Endorphin Pro 3 best suited for? 

1. Those who want shoes for racing or breaking their personal records 

This shoe comes with a full range of technologies to help you propel yourself forward, including responsive foam, a bouncy carbon plate, and Speedroll, which makes rolling through your stride easier. The foot strike feels effortless, and the shoe responds perfectly when landing on the midfoot or forefoot. You do not have to worry about missing the sweet spot, and all of this makes it easier to achieve better race times and break personal records. It is an excellent aid.

2. Those who want to try (but have never tried carbon-plated shoes before)

Because the Endorphin Pro 3 (specifically the 3 model) feels more user-friendly and less stiff, beginners who want to experience full-speed running can easily switch to carbon-plated shoes. This is why I say that. Compared to the Carbon X, Vanish, or Next, I believe the Endorphin Pro 3 offers more features, requires less adjustment, is easier to understand and control, and lasts longer. This makes it ideal for those who have never tried them before and want to give them a go. It is fun, easy, and lasts a long time.
