HOKA Cielo X1 Review: The Bold New Challenger in the Super-Shoe Wars

HOKA's first proper carbon-fibre race shoe targets the Vaporfly and Alphafly head-on with a radical geometry and the brand's signature maximalist cushioning. Does it deliver?

HOKA has been circling the super-shoe market for years with its Rocket X line, but the Cielo X1 is a genuine swing at the podium. It's unlike anything else in the brand's lineup — and unlike most shoes on the market.

The geometry is the story:

The Cielo X1 features an extremely rockered platform with a sky-high toe spring. The moment you pick it up, you understand HOKA's thinking: they want you to roll through your gait cycle with maximum efficiency, like a rocker-bottom shoe designed for speed rather than recovery.

The foam:

HOKA's new PEBA-based compound (they call it Cielo foam) is the softest, most responsive material they've ever produced. It rivals ZoomX in terms of energy return and is notably more durable.

On the road:

At easy and moderate paces, the Cielo X1 feels almost too lively — the rocker wants to push you faster than you intended. At race pace, it comes alive. Runners who tested it at sub-4:00/km pace reported a sensation closer to the Alphafly than anything else at this price.

Verdict: HOKA has built a legitimate race-day shoe. It won't suit every runner — the geometry is polarising — but if you're looking for an alternative to Nike's dominance, the Cielo X1 is worth trying on.
