Saucony Endorphin Elite 2 introduction:
Ivan: The first edition of the Saucony Endorphin Elite was renowned for its snappy, aggressive nature. This made it one of the most efficient super shoes on the market. Although its distinctive upper didn’t appeal to everyone and the outsole occasionally lacked traction, the explosive ride it delivered was undeniable. Now, with the second version released in limited quantities ahead of the Olympics, we’ve had the chance to put it through rigorous testing. We’re eager to share our insights on this truly unique super shoe. One which is sure to make waves when it finally re-launches in the spring of 2025.
Saucony Endorphin Elite 2 upper:
Ivan: Let me start by saying that I find the Saucony Endorphin Elite 2 to be a real beauty. While design is always subjective, the clean white look with splashes of purple and orange is particularly striking to me. The see-through knitted mesh upper even has an almost tiger-striped pattern. This adds a super cool, unique touch. The silhouette and colour combo are reminiscent of the first version. However, the materials and upper structure are quite different.
One of the few issues some runners had with the first iteration was the unconventional upper. This didn’t always provide the desired comfort and lockdown due to its stretchy materials. While the upper on the Endorphin Elite 2 feels more traditional and less experimental, the fit still isn’t perfect – at least not for my foot shape and preferences. True to the Saucony Endorphin line, the toe box remains on the narrow side. Furthermore seems to run slightly short in length. Other than that, the toe box offers decent volume, and the upper feels light and breathable. It has a somewhat rigid structure, with plastic-like threads holding together the softer mesh that connect the top part to the midsole. This gives the shoe a raw, simplistic look that still appears thoughtfully designed.
Where I struggle more with the fit is in the heel and midfoot lockdown. The more stretchy materials in the back part and general fit reminds me of the Endorphin Pro 4, so if you like that accommodating, sock-like construction, you’ll probably enjoy the one in the Endorphin Elite 2 as well. The laces and fully attached tongue are very stretchy, the midfoot is fairly wide for a race shoe, and the moulded 3D heel counter is completely flexible. Some runners will appreciate this unobtrusive and adaptable upper, but I find it lacking in hold and structure. I have to really tighten the stretchy laces, and while this doesn’t cause discomfort, I prefer a tighter, more secure hold in the back part of the shoe.
Saucony Endorphin Elite 2 midsole:
Ivan: The real highlight of the Saucony Endorphin Elite 2, and the reason I’m convinced it will make waves when it hits the broader market next year, is the midsole. More specifically, the midsole foam compound, which is truly one-of-a-kind. Saucony describes it as a next-generation super foam cushioning, though they’ve been tight-lipped about the exact technology behind it. All I can say is that it’s unlike anything I’ve ever experienced. Nothing like anything Saucony has previously offered.
Saucony’s past super foam compounds never ranked among the softest and most squishy on the market. But this new compound is at the opposite end of the spectrum. My first run in the Endorphin Elite 2 was the most unique running experience I’ve had since trying the Nike Vaporfly 4% in 2017. I’ve tested many running shoes with experimental designs and materials, but this unknown foam compound is something else entirely.
So, what does it feel like? The level of compression is unmatched – insanely soft and squishy, reminiscent of some next-level supercritical PEBA. At first, I wasn’t sure what to make of it, but after some long, tough sessions, I feel like I’ve got a handle on what this new foam brings to the table.
First, let me be clear: this is one of the most unstable super shoes out there. Yes, the platform is reasonably wide, and it features a lateral cutout, likely to prevent early collapse. However, the extreme softness and sink-in effect require constant micro-adjustments throughout the gait cycle. First time I was cornering, I was genuinely concerned about twisting my ankle. Over time, I’ve adapted to the foam’s lively nature and learned to manage quick direction changes. But, caution is advised if you don’t have strong ankles or need to navigate courses with lots of sharp turns.
The ride itself is unique. After the initial sink-in, the foam seems to have some properties that help minimise leg fatigue. It left my legs feeling surprisingly fresh even days after hard sessions. It’s comparable to some of the most protective super trainers out there. At slower paces, the softness is noticeable along the entire length of the shoe. At higher speeds, the foam firms up in the forefoot, preventing it from feeling too unresponsive during races. Despite being soft and squishy, it delivers substantial energy return.
During longer runs, I’ve noticed the soft foam compressing enough that the plate beneath becomes a bit noticeable up front. Personally, I appreciate this, as it adds a bit of responsiveness at toe-off that the Endorphin Elite 2 might otherwise lack. However, as a lighter runner, it’s difficult to say if heavier runners might bottom out more to the point of becoming uncomfortable.
Even with the inclusion of the fork-shaped carbon plate, the so-called Speedroll Technology isn’t as pronounced as in earlier Endorphin models. The foam’s softness mutes some of the snappiness and roll. That said, the rocker is still present and assists nicely in the heel-to-toe transition.
Summing all this up is challenging. Saucony simply describes it as having ‘Ridiculous Rebound’, and I think that’s a fair summary. It’s something you really need to experience firsthand to fully understand.
Saucony Endorphin Elite 2 outsole:
Ivan: Unfortunately, the outsole grip of the Saucony Endorphin Elite 2 doesn’t quite match the impressive performance of its new midsole compound. While it performs adequately in dry conditions, it struggles significantly in wet ones – a challenge I’ve encountered more than once recently. This lack of grip is particularly concerning given how lively the midsole already feels underfoot.
To be fair, the outsole coverage on the Endorphin Elite 2 is decent, and I haven’t noticed any wear and tear on the relatively thin layer of rubber so far. However, it is very smooth with minimal texture, and while some can get away with that, it’s not the case here. It handles well enough on clean, dry roads, which is expected for a road race shoe. But not all race courses are perfect, and it would be reassuring to use the shoe on sidewalks or less-than-ideal surfaces without worrying, especially as autumn approaches, bringing wet leaves and other slippery conditions.
Additionally, my pair has the added annoyance of a loud squeaking sound in wet conditions. It’s disappointing that Saucony continues to struggle with outsole performance, which could be a deal-breaker for runners in areas with challenging conditions.
Saucony Endorphin Elite 2 conclusion:
Ivan: The Saucony Endorphin Elite 2 is a standout, bringing something entirely different to the table. The true highlight is the midsole, delivering a ride experience unlike any other. While I wish the fit were more dialled-in and reassuring and the grip more reliable, these concerns almost fade when considering the bigger picture. This shoe is so unique that each runner will need to decide for themselves if the extreme softness works for them and if they can manage the inherent instability.
Nevertheless, it’s likely that most runners will appreciate the exceptional cushioning and the “Ridiculous Rebound” that Saucony aptly describes. Although the super shoe category is rapidly evolving and much may change before the Endorphin Elite 2 finally becomes widely available next year, I’m confident it will generate significant buzz when it happens.
