BITR's pick over the Rocket X3 when they want to run fast with an aggressive rocker.
+1 earlier review from Believe in the Run
The Cielo X1 2.0 is a significant upgrade over the original — now a true race shoe with a lighter build, an exaggerated rocker, and a more accommodating, bouncy ride that suits runners of all levels at any race distance.
Best for: Race day for a wide range of runners from half marathon to marathon; accessible to most ability levels
