Saucony drops PWRRUN PB from its flagship daily trainer. IncrediLUX, a supercritical A-TPU foam born in the Endorphin range, finally takes over at the top of the neutral line and stacks up to 43 mm under the heel. The result: the Triumph 24 sheds about thirty grams, gains liveliness and keeps the level of protection that has built the line's reputation for years. It's a substantial overhaul, delivered in a white/navy colorway as clean as the intent behind it.
The Triumph 24 is Saucony's max-cushion daily trainer, fully reworked around IncrediLUX, a supercritical A-TPU foam that is lighter and bouncier than the PWRRUN PB it replaces. With a 43 mm heel stack height and around 250 g in size 42, it targets runners covering 50 to 100 km/week who want both protection on long runs and liveliness on recovery runs. It delivers on that promise: A-TPU genuinely transforms the ride compared with the previous generation.
For several generations, the Triumph revolved around PWRRUN PB, an expanded EVA foam that was solid and predictable, but dense. What it wasn't: light, bouncy, or able to compete with the thermoplastic foams that have transformed the daily trainer segment since 2023. The Triumph 23 weighed 283 g in size 42, a figure that literally weighed on the reputation of an otherwise well-built shoe. Saucony knew it.
IncrediLUX is an A-TPU (thermoplastic urethane) foam produced by supercritical expansion: the material is saturated with CO₂ under high pressure, then released abruptly to create a structure of fine, regular microbubbles throughout. The result is a foam about 30% lighter than EVA at equal volume, with more rebound and better energy retention over long distances. Saucony first rolled it out on its racing range (see our reviews of the Endorphin Elite 3 and the Endorphin Speed 5) before bringing it down to the daily trainer. It's exactly what happened with PEBA at Hoka and New Balance: premium technology trickles down to daily trainers.
On the Triumph 24, IncrediLUX stacks up to 43 mm at the heel and 33 mm at the forefoot, with the drop kept at 10 mm. The extra stack height comes with a weight cut: the shoe drops to around 250 g in EU size 42, versus 283 g for the previous model. Thirty-three grams saved purely thanks to the density of the new foam. The XT-900 outsole (carbon rubber) carries over, which ensures continuity on durability.

If you already own the Saucony Triumph 23 and can't decide whether to upgrade, here are the facts side by side:
| Criterion | Triumph 23 | Triumph 24 |
|---|---|---|
| Main foam | PWRRUN PB (expanded EVA) | IncrediLUX (supercritical A-TPU) |
| Heel stack height | 37 mm | 43 mm (+6 mm) |
| Forefoot stack height | 28 mm | 33 mm (+5 mm) |
| Weight (EU size 42) | ~283 g | ~250 g (-33 g) |
| Drop | 10 mm | 10 mm |
| Outsole | XT-900 | XT-900 |
| Perceived liveliness | Average (compressive foam) | Clearly better (A-TPU rebound) |
| Price in France | €175 | €190 (+€15) |
The conclusion is clear: the Triumph 24 beats the 23 on every criterion that matters for a daily trainer (weight, stack height, liveliness), for a modest price increase of €15. If you find the Triumph 23 on sale, it remains a sensible choice for runners who like the firmer feel of expanded EVA. Otherwise, the 24 is the one to get.
The Triumph 24 also holds its own against its direct rivals. The Hoka Clifton 11 remains more versatile and a little cheaper (around €155), but Hoka's CMEVA foam loses rebound compared with IncrediLUX over long distances. The New Balance Fresh Foam X 1080v15 offers comparable comfort but costs slightly more and is a little heavier. The Brooks Ghost 18 (€150) is more affordable, but with a stack height of only 36 mm it offers less protection over very long distances.
We put 120 km on the Triumph 24 in varied conditions: recovery runs at 6:00/km, long runs of 22 to 30 km at 5:15/km, and a few stretches at half marathon pace (4:30 to 4:45/km) to find its limits.
RunMorph tip: the Triumph 24 comes alive between 4:50 and 6:30/km. Below 4:30/km on long repeats, it lacks the propulsion a carbon plate would provide. For interval sessions with more than 20 min at a fast pace, the Endorphin Speed 5 is a better choice. For everything else, the Triumph 24 excels.
Step-in feel and upper. The structured engineered mesh wraps the foot without squeezing. We noted no lateral pressure, even on 30 km runs. The padded tongue and foam-lined ankle collar limit irritation on long efforts. The fit is slightly wider than the Triumph 23: runners with narrow feet may need to re-lace for an optimal hold.
How the foam behaves. You feel IncrediLUX right away. Compared with PWRRUN PB, the return is livelier, almost fizzy, without tipping into twitchy. On recovery runs, protection is maximal: your legs finish the session less tired, especially on runs over 20 km. On faster stretches (5:00 to 4:45/km), the foam responds with a responsiveness the previous generation never had.
Outsole and grip. The XT-900 provides solid grip on dry and wet asphalt. Wear after 120 km is very reasonable: XT-900 rubber is among the most durable on the market in this segment. The outsole pattern includes longitudinal grooves that follow the natural flex of the foot without stiffening the transition.
The Triumph 24 is designed for long hours on the road. It slots naturally into marathon or half marathon training, protecting your muscles on runs of 20 km and more while staying enjoyable on recovery runs at an unstructured pace. Rotated with a lighter interval shoe, it covers most of what a serious runner needs.
At RunMorph, we typically pair it with the 42 km marathon plan to log your training kilometers while saving your legs, or with the advanced half marathon plan to lock in your Sunday long runs. It works best in a rotation with the Saucony Endorphin Elite 3 for races and the Endorphin Speed 5 for tempo sessions.
The Triumph 24 is a clear success. IncrediLUX delivers on its promise: lighter, bouncier and more protective than PWRRUN PB, it turns a decent daily trainer into a benchmark for serious runners covering 50 to 100 km/week. Saucony managed to add 6 mm of stack height while cutting 33 g: that was the main criticism of the Triumph 23, and it's been fixed.
The price question is legitimate at €190. The Hoka Clifton 11 and the Brooks Ghost 18 sell for under €160 and have excellent qualities. But neither offers supercritical A-TPU or the rebound of IncrediLUX. If budget is a constraint, the Clifton 11 remains the best compromise. If you want the best Saucony daily trainer available for the road today, the Triumph 24 is worth its price.
RunMorph overall score: 8.5 / 10
