Key takeaways
The tester feels that the Rocket X Trail doesn’t recreate the “explosive” feel and the magic of the Rocket X 3 on the road, because trail constraints limit the energy returned. However, they judge the shoe stable and effective enough to go fast on mixed terrain, and to stay in good shape even when the path becomes more complex. They conclude that it’s a convincing option for the “middle ground” between road shoes and traditional trail shoes, but not for very technical mountain races.
