The Racing Shoes Behind Our Personal Bests: 6 Standout PB Shoes

Introduction

Every runner has a shoe they credit, at least partly, with a breakthrough performance. We asked a group of runners to look back at the shoes they wore for their personal bests, from parkrun sprints and 5K races all the way up to marathons and 100-mile ultras. The results are a genuinely varied picture of the modern racing shoe market: Saucony, Asics, Nike, Hoka, Puma and On all feature, which says a lot about how level the playing field has become since the early days of carbon plate shoes.

One honest caveat from everyone involved: shoes do not make the PB. Training does. A good racing shoe helps you unleash the benefits of the work you put in, but it cannot make up for a lack of conditioning. With that said, the right shoe can absolutely give back a little extra efficiency when you are holding on in the final miles.

How We Chose These Shoes

The picks below come from real race results across 5K, 10K, half marathon, marathon and ultra distances. Some are recent, others are a trip back into the early days of carbon racing shoes. What unites them is that each one delivered when it mattered: comfortable enough to race in, fast enough to justify the choice, and reliable over the distance.

The development of carbon plate racing shoes over the last few years has been remarkable. Five years ago, almost every PB shoe in a roundup like this would have been a Vaporfly of some kind. Today, excellent options exist across every major brand, and a much wider range of designs now works for different runners and different race distances.

Saucony Endorphin Pro 3

The Saucony Endorphin Pro 3 is the shoe behind the most impressive stretch of results in this roundup: a 5K PB of 18:18, a 10-mile PB of 1:04, and a marathon PB of 2:53 at the 2023 Berlin Marathon, with a 2:55 in Chicago the year before. Across two major marathons and nearly every other distance, the feedback was the same: comfortable, natural, with a pleasant bounce, and no discomfort issues even at full marathon distance.

It felt relatively stable for a super shoe and simply worked. The one lingering question is whether the same magic still holds a couple of years later, and it is a shoe that deserves another marathon outing to find out.

Asics Metaspeed Sky Paris

The Asics Metaspeed Sky Paris is the standout of this entire group. It delivered a marathon PB of 2:54:40 at the Manchester Marathon and, just six days later, a 17:59 5K at a closed park circuit. One runner in the group also set a sub-70 half marathon and a 2:25 marathon in London with it, then improved again to 2:25 at Seville, calling it the best racing shoe on the market for their needs.

What makes it work is the full package: a light, racy, airy upper, a big stack of bouncy energetic midsole foam, and a stiffness in the plate that adds genuine snap rather than just softness. It dampens enough road impact without feeling disconnected, lands with real precision, and is wonderfully agile. It also comes in at a competitive price, which makes it an easy recommendation if you want one shoe to chase PBs across every distance.

Puma Fast-R Nitro Elite 3

The Puma Fast-R Nitro Elite 3 is the newest shoe here and has already produced a fastest-ever parkrun of 17:41 around a West London park. Its decoupled midsole design with a dramatic heel cutaway takes some learning: it is not the most natural shoe to run in out of the box, and finding the sweet spot takes a few runs. But when you hit the ground right, it feels smooth, fast, efficient and punchy, and it performed well even on less smooth ground.

There are legitimate concerns to weigh up. The fit runs narrow and quite long in the toe, and some ground impact comes up under the ball of the foot, which may matter over a full three-hour marathon effort. As a short-distance weapon, though, it has been seriously impressive, and it is noticeably lighter than many of its rivals.

Hoka Rocket X 2

The Hoka Rocket X 2 delivered a 5K PB of 19:59 at an Olympic Park run-through event, and it proved the perfect shoe for that race. The ride is very responsive, lively and aggressive, with a strong sense that the shoe controls your stride at shorter distances, and it had exactly the pop needed over 5K race pace. It is a shoe this runner still rates highly and one you can still find today.

The original Rocket X also earned its place in history here, producing a 39:39 10K that remains the only sub-40 run. It was a light, skinny-fitting first carbon racing shoe that delivered an excellent experience at the time, even if better options now exist in the current range.

Nike ZoomX Vaporfly Next%

The Nike ZoomX Vaporfly Next% is the shoe behind a half marathon PB of 84 minutes flat at an undulating, windy reservoir event, and it came close to lowering that again at the Berlin Half. It is one of the lightest shoes in this roundup at around 187 grams, with an 8mm drop that feels aggressive on paper but surprisingly normal in practice.

The updates over earlier versions were meaningful: laces that stayed tied securely and an upper that moved from sail-like material to a much more knitted feel. The main weakness is outsole wear for heel strikers, which is a known trade-off of the design. Even now, it remains a shoe this runner would happily race in again.

On Cloudboom Strike LS

The On Cloudboom Strike LS deserves a special mention for an almost-legendary performance: it carried a runner on course for their first sub-70 half marathon, with roughly 20 seconds in hand at the 12-mile marker, before a misrouted final corner shortened the course to 160 metres short of the distance. The clock read 68:58, but it was not a legal PB.

It is an expensive shoe and the laceless upper will concern some buyers, which is why it does not top every recommendation list. But it shares a lot with the Metaspeed Sky Paris: lightweight, responsive and fast, without being overly soft. If you like the idea and the fit works for you, it is a genuinely excellent carbon plate racer.

For the longest efforts, a three-shoe rotation of Brooks Hyperion Max 2, Saucony Endorphin Speed 3 and On Cloudmonster Hyper powered a 100-mile PB of 22:06:36, cutting around four hours off the previous best with zero blisters and no battered toes. That multi-shoe strategy, changing footwear to vary the load on tired feet, is well worth considering for ultra distances.

Overall Buying Advice

If you want a single shoe to chase PBs across every distance, the Asics Metaspeed Sky Paris is the strongest all-rounder here: light, propulsive, cushioned enough for the marathon and sharp enough for a 5K. The Saucony Endorphin Pro 3 remains the comfort-first marathon pick, while the Puma Fast-R Nitro Elite 3 and the Nike ZoomX Vaporfly Next% shine for shorter, faster efforts. For big-cushion marathon racing, options like the Nike Alphafly remain strong, and for ultras, prioritising toe box room and reliable comfort matters far more than outright speed.

And remember the caveat that opened this article: the shoe does not make the PB. The training does. Pick the shoe that fits your stride and your race, then put in the work.

Conclusion

The range of shoes in this roundup tells a clear story about where racing shoes are today. There is no single dominant model any more, just a healthy spread of excellent options across brands and budgets. Match the shoe to your distance and your feet, trust the training, and the PB will follow.
