The dynamic single layer of engineered mesh makes the upper of the Cloudflash ultralight, dynamic, reactive and highly breathable.
But power without control is nothing. So we implemented no-sew support in the forefoot and metatarsal areas aids feet as they tire toward the end of the race.
Boosting this, is the non-linear lacing system. Built wider at the base of the foot, it’s designed to provide increased stability and agility, particularly when rounding corners at speed.
And, speaking of taking on tight turns, just like the Cloudboom, the Cloudflash uses a specially selected grip rubber for the outsole’s overlay. It’s already come in for praise, with one reviewer saying it “provides better traction on wet roads than any other road racing shoes we have tested.”

Small Changes, Big Impact
Another key new feature is the introduction of an extra Cloud element in the shank (or the middle of the shoe) on the medial side. This provides stability, effectively distributes pressure, adds grip and protects forefoot Clouds - which are often the first to wear down when you do a lot of hard running.
The new shape of the heel collar was developed based on feedback from some of our elite athletes, including champion triathlete Javi Gomez. Its lower curve reduces pressure points on the ankle and molded padding provides a secure fit that keeps you in control even when you’re really pushing. In triathlon especially, this is crucial to help speed up transitions.
And when we say we looked at every detail, we really mean it. Right down to the re-engineered sockliner. The new version is thinner than any we’ve made before at just 3mm, yet has a much higher rebound and resilience thanks to the cutting-edge materials we’ve used.
