Saucony Endorphin Elite 3 First Run Review: Soft, Bouncy and More Controlled

Introduction

Saucony’s flagship carbon racer has a clear identity: it is the softest, squishiest shoe in the super shoe class, and the Endorphin Elite 3 leans into that even harder while trying to rein in some of the wildness of the previous version. The Incre-Run foam is still here in full force, but Saucony has added more foam under the heel and in the lateral area for stability, and reworked the carbon plate to add a bit more punch.

We took it out for early test miles across easy running, fartlek sessions, a slow 10K race and some near-marathon-pace work. Here is how those changes stacked up first time out.

First Impressions and Key Specs

The stack stays at 39.5 mm in the heel and 31.5 mm in the forefoot, same as the Elite 2, with an 8 mm drop. In a UK 8.5 / US 9.5 it weighs 221 grams or 7.8 oz, slightly heavier than the last generation. It costs $290 in the US, a bump over the Elite 2 that puts it among the most expensive race day shoes available.

The midsole keeps the highly compressive TPE-based Incre-Run super foam, now with additional foam under the heel and on the lateral side to make the shoe a little more approachable. The full-length carbon plate remains slotted and is heavily fluted for more stiffness, working with the Speedroll rocker geometry for smoother toe-off and transitions. Up top there is a light, breathable, highly perforated engineered mesh upper with the integrated booty-style tongue kept over from before, standard lacing on top, minimal heel collar padding and virtually no heel counter. The outsole gets a generous rubber covering in the key impact zones, thick at the heel, which suggests Saucony chose some durability over shaving every last gram.

Fit and Sizing

Fit feedback from our testers was largely positive, with a consistent theme: go true to size, but the toe box runs snug for some. One tester who runs in UK 9.5 found the fit forgiving for a race shoe, with plenty of flex in the toe box, good length and hold across the toe knuckles, and solid midfoot lockdown. The integrated booty-style tongue flexes enough to accommodate high insteps comfortably.

Another tester in a US 10 normal size found the shoe fits a little shorter and closer around the toes than other Sauconys, almost like a half size down, which suited a preference for a dialed-in racing fit. The upper held the foot well even cornering at speed. A third tester with less space for the big toe than usual in their normal size also stayed true to size and had no issues, but noted some runners might want to go up half a size, especially for marathon room around the toes.

Comfort on the foot is a genuine highlight. The upper feels natural, airy and almost slipper-like, with a light hug rather than exposure. The trade-off is support: with almost no heel counter, some runners may find the combination of minimal structure and very soft foam leaves them wanting more, particularly if they land further back in the shoe.

Ride and Performance

This is still a very soft shoe. The foam is super squishy and highly malleable underfoot, delivering a feeling of big cushion with plenty of spring-back and bouncy energy. It is a little more controlled than the wilder Elite 2, but it still is not the most stable carbon shoe out there, and it will not suit runners who need high levels of support. The ride works best when you lock in your form and punch into the forefoot; do that and it is bouncy, springy and a lot of fun.

At pace it transforms. During warm-ups and cool-downs it can feel soft and slightly squirmy, but once up to speed it becomes far more purposeful, with directed spring and a good roll through the transition. One tester described it as a shoe that makes you go faster, feeling like jogging at paces quicker than an easy day. Over marathon-pace segments it felt genuinely good, and the big squishy bounce could protect the legs deep into a marathon.

There were quirks. One tester felt a strange vibration coming back from the forefoot of the plate, like running on a boardwalk, an odd sensation that brought extra bounce but was not entirely natural. The outsole rubber has also been placed more strategically than before, with more exposed midsole, so durability is something to keep an eye on.

Early Verdict

From the early miles, this looks like a refinement rather than a reinvention. The Elite 3 keeps the same foam and the same character as the Elite 2, with a bit more stability and control, and it has lost none of the fun. It should appeal to a wider range of runners than the last version, which some found too wild.

It nails comfort and fit, and early signs suggest it is soft and protective enough for long time on feet, potentially up to the marathon, including for heavier landers who find more pared-back shoes too minimal. The caveats: it is not the shoe for twisting, turning courses or uneven surfaces, and if you need stability when tired or when form goes ragged, it may find you out. Some testers also wondered whether they would want more snap in the final miles of a marathon, as very soft high foams can drag when you no longer have the energy to punch into them, unlike stiffer plated rides where the plate does more of the work.

Conclusion

The Saucony Endorphin Elite 3 is a soft-first carbon racer with a distinct personality: hugely bouncy, extremely comfortable and more approachable than its predecessor, but still relatively wild. It looks like a strong half marathon candidate and a promising marathon shoe for runners who love big cushion and can hold their form. If you prefer firmer, snappier super shoes or need serious stability, this one may not be your perfect match. A full verdict will follow once more race-paced test miles are in.
