Welcome to our guide to Saucony footwear! In recent years, Saucony has made a surge to being a leading brand given its variety of options, integration of foam technology into footwear, and ability to democratize high-performance materials in packages appropriate for all runners. They offer a vast array of footwear both for the road and the trails. In this feature we will cover Saucony’s history, unique technology, and their current running shoe lineup.

About Saucony

Beginnings and Boulders. Saucony was originally founded in 1898 (then known for their children’s footwear), but didn’t officially adopt the same Saucony until the 1960s. The name “Saucony” is derived from a Native term that means “where two rivers run together.” The rivers referred to exist in a part of Saucony Creek in Kutztown, PA. The logo bears a resemblance to this creek, with three boulders represented by three dots. Now these three dots hold the guiding “boulders of their brand: good performance, good health, and good community. 

Run for Good.
If you’ve followed Saucony for any amount of time, you’ve probably seen the phrase “Run For Good.” This phrase currently stands for two pillars of this company: good for the planet and good for the community. “Good for the planet” refers to their initiatives in creating more sustainable running products, which include a newer plant-based midsole and more sustainable upper materials. “Good for the community” emphasizes breaking dow barrier around race and gender by creating strategic partnerships and forming grants to promote healthy lifestyles for all people. This includes creating programs and policies that encourage representation from diverse groups of people across and beyond the organization, including Running Industry Diversity Coalition (RIDC), Black Men Run, and Black Girls RUN!. Additionally, they have partnerships with Boston Children’s Hospital and New Orleans Children’s Hospital to collaborate on footwear design and services. 

Contributions to Research. An interesting aspect of Saucony is its connection to the research world. A long-standing athlete of theirs is Jared Ward. Ward has been an adjunct faculty member at BYU and contributed to the literature exploring running economy and footwear and the individualization and progression of running mechanics. One of the articles he collaborated on with Hunter McLeod contributed to our understanding of the individual response to super shoes. Their close ties to the research world have undoubtedly influenced their footwear design for the better, leading to different options for different runners.

Technology to Know

Saucony's EVA blend seen in everyday training models like the Guide and Kinvara.

Their next level of foam which features a beaded PU-based cushioning. This is seen in many of their max cushioned models like the Triumph. It has been found to be a highly durable midsole along with being protective.

Saucony's PEBA blend. They indicate that it is 50% lighter than their EVA, consistent across temperatures, and features a high durability. It can be found in their performance models like the Endorphin Speed and Tempus along with the Endorphin Pro.

PWRRUN HG. Saucony's latest PEBA blend which they state to have 95% energy return. This is found solely in their Endorphin Elite model currently.

Saucony's first take at a bio-based midsole, PWRRUN Bio+ is a 55% corn-based midsole made with Susterra® propanediol.

Speedroll is a term coined to go alongside their Endorphin series. It is the combination of cushioning and stiff forefoot rocker that works together to propel you forward.

PWRTRAC. Saucony's outsole formula for their trail running shoes.

Hollow Tech. The name of their posting system that is now seen in the Omni series. It features a clear plastic piece embedded in the shoe on the medial side.

FORMFIT. Saucony's description of how they create their fit. It is a combination of how the shoe wraps your foot from below through a bit of a cradled design directly underfoot along with structured elements on the upper to wrap the shoe around your foot securely.

Science Feature: Are Super Shoes ALSO Protecting Runners More Than Ever Before?
By Matt Klein

The Saucony Endorphin Elite is a sign of super shoes moving to a completely different level. While the original Nike Vaporfly was found to provide energy return levels around 87%, the Saucony Endorphin Elite has been reported to provide 95% energy return (Hoogkamer et al., 2018).  While the Vaporfly, Saucony Endorphin Pro 3, Asics Metaspeed Sky and others still sit in the super shoe category, newer products like the Saucony Endorphin Elite, Mizuno Wave Rebellion Pro and even the more seasoned Nike Alphafly are sitting at an almost entirely different level in regards to aggressiveness and performance. We will likely see more companies enter into this level, which begs the question of whether we need a different name for this category.

As exciting as the new shoes are, they are still tools that will work for specific runners and others that are patient and cautious enough to figure out how to use them. These will not make you invincible and while some people report reduced soreness after hard workouts in them, others have reported more due to their bodies have to get used to something so drastically different. Though we do not yet have evidence on how they affect injury rates, from clinical experience (expert opinion) it appears that injury rates are not changing (they are still high). The types of injuries, however, are changing. As expected with more aggressive, softer, stiffer and rockered shoes, I have seen more hamstring, calf, Achilles and soft tissue injuries compared to more bone stress injuries seen during the minimalist era.

As we have stated repeatedly, these shoes are tools, they will impact your body in different ways and you must continuously condition your body to handle those changes. As we move to an even more aggressive level of performance footwear, working on single-leg stability on unstable surfaces (soft unstable foams), hip strength (stresses are moved proximally toward the hip), and resiliency of the Achilles tendon and calf (working with the plate and instability of the foams) are three major things I suggest that runners work heavily on if they want to use these new shoes. 

This does not mean that shoes like the Saucony Endorphin Pro 3 don't have a place. How people respond to these shoes are highly variable and dependent on many factors including the person's lower extremity stability, proprioception, unique biomechanics, sense of comfort and many other factors. There are some that will probably do better in the Endorphin Pro 3 while others will do better in the Endorphin Elite. There is also a group that will do better in the Kinvara! These options are now out there and we encourage people to explore what works best for them. The "what works best" search is what made us start this website, so know that from our experience, what will work for you may change over time. So enjoy the many changes occurring in the running industry as they are moving toward people having more options, but will require people to explore what works for them as individuals.
