Saucony 2025 Technologies: everything you need to know about new running innovations

The 2025 technologies from Saucony: what you need to know

In the world of running, innovation never stops, and Saucony is living proof. In 2025, the American brand continues to redefine the standards of cushioning, performance, and comfort. Whether you are a beginner runner looking for support or an experienced athlete seeking efficiency, understanding the new technologies integrated into Saucony models is essential for making the right choice.
In this article, we review the main innovations of the Saucony 2025 trail-running range: their principles, advantages, and impact on your running sensations. The goal: to help you find the ideal pair to perform on all terrains.

Cushioning and foam technologies (midsoles)

- PWRRUN

The PWRRUN foam is a "classic" EVA foam optimized by Saucony for a good balance between cushioning and stability. It remains a reliable base in many training models. 
→ Example: the Saucony Guide 18 uses it to provide consistent cushioning in a stability model (with CenterPath technology).
→ Example: the Saucony Ride 18 combines PWRRUN or PWRRUN+ depending on the version for a good daily use compromise.

- PWRRUN+

This TPU (thermoplastic) version provides a more durable and comfortable foam for long distances. Saucony offers it as a "workhorse" for daily runs. 
→ Example: the Saucony Ride 18 is often cited as a typical model incorporating PWRRUN+.

- PWRRUN PB

Following recent trends, the PWRRUN PB foam (based on PEBA) is lighter, more responsive, and performs well across a wide temperature range. 
→ Example: the Saucony Endorphin Speed 5 incorporates it to ensure dynamism in fast efforts. 
→ Example: the Saucony Hurricane 25 uses a core of PWRRUN PB combined with PWRRUN for enhanced stability.

- PWRRUN HG

This is a high-end foam, still based on PEBA, designed to provide a very high energy return (up to ~95%) during performance runs or competitions. 
→ Example: the Saucony Endorphin Elite 2 is a "super shoe" model that adopts this cutting-edge technology (with incrediRUN in the 2025 versions).

IncrediRUN

For 2025, Saucony introduces or enhances IncrediRUN in its highest ranges. It is an even more aggressive foam, combined with propulsion plates to improve responsiveness. 
→ Example: the Saucony Endorphin Trainer combines IncrediRUN + PWRRUN chassis, making it a "daily super-trainer" for those who want high-end cushioning every day. 

HG + PB combinations

Some models mixing PWRRUN HG + PB offer the best of both worlds: the liveliness of HG + the softness or support of PB. 
→ Example: the Saucony Endorphin Pro 4 combines these technologies to optimize propulsion and comfort.

Structure, stability, and support technologies

- FORM Fit (FORMFIT)

This is Saucony's "enveloping fit" concept: the shoe conforms to the shape of the foot through internal layers and structural elements in the upper for secure support without over-compression.

- Speedroll

This is not a foam in itself, but a rocker geometry (curved shape) coupled with cushioning to promote a smooth transition and natural propulsion forward. Highly appreciated in racing models. 
→ Example: the Endorphin models (Speed, Pro, Elite) use the Speedroll concept.

- PWRTRAC

This is the rubber or outsole compound optimized for grip on varied terrains, especially in trail running. 
→ Example: the Saucony Xodus Ultra 4 or the trail versions of Peregrine use it to enhance traction on trails.

- CenterPath / Stability Geometry

Some shoes incorporate asymmetric geometry, wide "sidewalls", or guiding elements to help keep the stride centered (useful for slightly pronating runners). 
→ Example: the Saucony Hurricane 25, with a wide base and reinforced sidewalls, aims to provide stability and protection.

- Hollow Tech / Posting System

In "stability" models, a hollow piece (clear plastic) is integrated on the medial side to "post" the sole (add local rigidity) and limit foot collapse. 
→ Example: the Omni ranges or stability models use this type of structure. (Less common in ultra-modern ranges, but still mentioned in history)

Iconic Saucony 2025 models and their use

Here are some representative models (and available for purchase on AlpinStore) that illustrate the mentioned technologies:

Each model has its strengths depending on the type of run, the runner's profile, and preferences (dynamics, cushioning, stability, lightness…). Find all Saucony running shoes, and all Saucony trail shoes available on Alpinstore.
