Hoka Cielo X1 Long-Term Review: A Bouncy Carbon Racer That Grows on You

Introduction

The Hoka Cielo X1 arrived near the start of the year as Hoka’s new flagship racer, sitting above the Rocket X2 in both price and overall size in the brand’s lineup. It is positioned more as a long-distance racing shoe, while the Rocket X2 remains the lighter, more agile option. This review comes after around 210km of running in the shoe, including a half marathon, a parkrun, marathon training blocks, and plenty of hard sessions, so there is a good picture of how it performs and how it holds up.

Design and Build

The Cielo X1 costs £250 or $270 and is fairly heavy for a carbon plate racing shoe, weighing 253g (8.9oz) in a UK size 9, with a 7mm heel-to-toe drop. The design is bold: two layers of Hoka’s Peber foam sandwich a winged carbon plate intended to add stability, with cutouts in both the midsole and the plate itself to trim weight. The outsole offers good rubber coverage for the foam that touches the ground, though a small amount of exposed foam at the heel will wear down for heel strikers.

Fit and Comfort

The fit has been excellent in a normal running shoe size, with a snug but not restrictive hold through the midfoot and forefoot. The knit upper with a partially gusseted tongue creates a booty-style fit that locks the foot in naturally, so much so that even with laces undone the lockdown holds up well. The heel design deserves special mention: two small strips of padding and generous open space at the back mean no Achilles irritation, even during flare-ups caused by other racing shoes with stiffer heel counters.

Ride and Performance

This has become a go-to shoe for hard training sessions, and the reason is simple: the ride is bouncy, fun, and fast while staying surprisingly controlled and stable despite all the midsole cutouts. It works across a wide range of paces, from relaxed easy miles in long progression runs to flat-out short reps at the track and hill sprints. In long intervals like 10 x 1 mile, the combination of bounce, plate efficiency, rocker geometry, and foam protection keeps legs fresher, and the shoe retains its springiness to the end without bottoming out.

It also handles rougher surfaces, cambered pavements, and even light trails better than wilder super shoes, feeling like a tamer alternative to something like the Mizuno Wave Rebellion Pro 2 or the Adidas Prime X Strung. The main caveat shows up late in sustained races: when genuinely tired, the shoe’s size makes it harder to turn over compared with lighter racers like the Adidas Adizero Metaspeed Sky Paris or Nike Vaporfly 3, because the bounce rewards forceful footstrike.

Things to Consider Before Buying

The laces are a small annoyance; they came undone twice in 210km, once during a half marathon, and swapping them would be an easy fix. The weight is the bigger sticking point: on paper, lighter and cheaper alternatives exist, and in a hard-fought race finish the Cielo X1 can feel big. The price is also at the top end of the market, which makes it a considered purchase rather than an obvious one.

Durability After 210km

Durability is a genuine strength. Compared side by side with a brand-new pair, the 210km shoe still feels just as bouncy, with the midsole unchanged apart from a slight color shift and no upper wear at all. The only wear is a small tear in the exposed heel foam on the heel-striking side. The foam also bounces back quickly between runs, so it can be used several times a week without losing its spring, making it one of the few carbon plate shoes that works well as a regular training shoe.

Verdict

The Cielo X1 is one of the best new carbon plate shoes released this year, and it may end up underrated because of its headline weight and price. In pure performance, it delivers one of the most fun rides available, lasts well, and offers plenty of protection, making it a very good marathon racing option and a rare super shoe that doubles as a high-mileage trainer. If Hoka trims a little weight in the next version while keeping the bounce, it will be a serious contender.

Conclusion

For runners who want a bouncy, protective super shoe they can actually use often, in training and on race day, the Cielo X1 is an easy shoe to love. Just weigh the weight and price against lighter racers if maximum speed at any distance is the priority.
