Best Super Shoes 2024: Four Carbon-Plated Racers Compared

Introduction

Four super shoes, one comparison. The Nike Alphafly 3, Puma Fast-R Nitro Elite 2, Saucony Endorphin Pro 4, and Hoka Cielo X1 all play in the same carbon-plated racing category, but they take very different approaches to cushioning, fit, and ride feel. All four are apparently legal for elite competition, though for most runners that matters far less than how the shoe actually rides. Here is how they stack up against each other.

How They Compare on the Numbers

The Alphafly 3 is the widest shoe of the four, both in the forefoot and especially in the heel, where it measures a full 2 cm wider than the Puma Fast-R Nitro Elite 2 and nearly a centimeter wider in the forefoot. That extra surface area gives it a planted, generous footprint.

The Cielo X1 is the heaviest by a clear margin at 300 g in a UK size 11 (US size 12), and it also measures the tallest in the heel. Despite the Alphafly 3’s wider dimensions, it comes in roughly 30 g lighter than the Hoka, and you can feel that difference on foot.

All four midsoles use PEBA-based foam with an average softness of about 22 to 24 on the Shore A durometer scale, noticeably softer than the roughly 28 average across running shoes generally. These are genuinely soft, highly cushioned platforms.

Nike Alphafly 3: The Maximal Racer

The Alphafly 3 rides light and airy thanks to a very thin upper, though the weight distribution sits noticeably low in the midsole and outsole, giving it a bottom-heavy character. On longer runs, that generous cushioning can start to feel less present in the latter miles, but it remains a slightly better training option if you like throwing faster-paced sections into your long runs.

The upper is a real improvement over the Alphafly 2, with a much better defined fit and shape. Grip is a genuine strength too, with better performance on corners than the Cielo X1. The trade-off is durability and price: at £285 it is the most expensive shoe here, and availability has been a real frustration, with colorways selling out almost instantly.

Puma Fast-R Nitro Elite 2: The Dragster

The Fast-R Nitro Elite 2 is the outlier, with an extra-long carbon plate that protrudes out the front of the shoe. Despite the unusual geometry, road and debris strikes have not been a problem in testing. This is a true race fit: very little room in the toe box, minimal excess material, and a much narrower heel than the Alphafly 3.

Weights are nearly identical between the Puma and the Alphafly 3, and both feel bottom-heavy, but the implementations differ sharply. The Puma is considerably softer in the forefoot and rewards runners who drive hard into the front of the shoe, while the plate stabilizes and propels you forward onto toe-off. It is also proving durable, with around 75 miles logged showing very little wear beyond a touch of rubber at the heel.

It feels more nimble over 5 to 10k efforts and performed well in a hilly half marathon. For heel stability and all-out racing sessions, the Puma is the clear winner of this pairing, though the very thin upper will not suit everyone.

Saucony Endorphin Pro 4: The Versatile Racer

The Endorphin Pro 4 has one of the most attractive profiles in the category and feels light and nimble on foot, roughly 20 g lighter than the Alphafly 3 and about 50 g lighter than the Cielo X1. A newly improved outsole elevates it to the top tier, fixing the outsole problems that affected the Pro 2 and Pro 3.

The ride is propulsive with a softer, more traditional carbon-plated feel, helped by a responsive foam combination and an extra foam layer under the foot that makes it less squashy than the Pro 3 and more forgiving in the forefoot. If you liked the Vaporfly 4%, this is the shoe for you.

It is the more versatile choice across all the popular race distances, while the Alphafly 3 has become more of a niche half and full marathon shoe. At £230 in the UK it undercuts the Alphafly 3 by £55, and unlike the Nike it is actually easy to buy. If versatility and availability drive your purchase, this is the straightforward pick.

Hoka Cielo X1: The Wild Card

The Cielo X1 feels more like a shoe you lock into a pace and hold, with a very aggressive rocker and a thicker, more substantial upper material. It is not the shoe for repeats or intervals, but it handles sustained blocks of faster effort well and offers a more consistent, less generous ride.

Durability looks strong, with substantial rubber thickness in the outsole likely to hold up over many miles. At £250 it is still expensive, but £35 cheaper than the Alphafly 3. On pure enjoyment and usefulness in a shoe rotation, the Cielo X1 makes a compelling case, especially for runners who want something they can reach for on a more daily basis.

Overall Buying Advice

The Alphafly 3 remains a formidable but niche and expensive option, best for half and full marathon racing if you can find it in stock and get used to its ride. The Puma Fast-R Nitro Elite 2 is the aggressive racer’s choice for short distances and all-out sessions. The Saucony Endorphin Pro 4 is the most versatile and sensibly priced of the group, and the Hoka Cielo X1 is the most enjoyable and durable all-rounder. Choose based on whether you prioritize outright speed, versatility, or everyday enjoyment.

Conclusion

These four shoes aim for the same target with very different implementations. If you want one pick on versatility and value, the Saucony Endorphin Pro 4 is the easy call. For raw racing aggression, the Puma stands out. For enjoyment and rotation value, the Hoka earns its spot, and the Alphafly 3 rewards patient, pace-focused marathoners who can live with the price and availability.
