On launched their innovative new cushioning technology, dubbed Cloudtec Phase, in March 2023 with the release of the new Cloudsurfer. Cloudtec Phase was created using computer-based simulation technology that enabled shoe designers to predict the impact between the foot and the ground while running. This allowed designers to fine-tune the ride of the cushioning based on biometric data from over a thousand different runners.
The result is a buttery-smooth ride that rolls you forward with every step. But the best part? The On Cloudeclipse features a double-layer of Cloudtec Phase cushioning, versus the single layer used in the Cloudsurfer.
“I am stoked on this shoe!” says Kate. “The Cloudtec Phase cushioning is so dense. It provides a lot of impact protection for my joints, and it just feels good for standing, walking and running. The foam is soft and compresses a bit underfoot, but it’s thick enough that it only squishes down a little bit at the start of impact. I can get into a better rhythm on the run when my shoe isn’t overly squishy. The shoes also have a really high stack height, and the wide platform keeps them feeling stable.”
On describes the On Cloudeclipse cushioning as being “noise canceling for your feet,” and reviewers agreed.
“The Cloudeclipse is my new favorite On running shoe because I can feel less of the ground under my feet compared with other models, which is always the feeling I’m going for,” says Caroline.
Reviewers also lauded the responsiveness of the Cloudeclipse, which is due to the Cloudtec Phase cushioning. According to On, the oblong-shaped pods underfoot act as dominoes. As each pod collapses under your weight, it falls into the next, creating a rolling sensation that helps you transition from heel to toe.
“On my first test run, I was just rolling along with ease,” says Travis. “It was one of those runs where you feel like you’re going easy, but when you look at your watch the pace is much faster than anticipated. It was one of the best runs I’ve had in a couple of years—the shoes just made the run feel so much fun.”
Cloudtec Phase cushioning isn’t the only feature to thank for the shoe’s energetic feel. The Cloudeclipse features a redesigned Speedboard, which is a rigid plastic plate embedded inside the midsole of most On running shoes. The Speedboard compresses under your weight as you land and then rebound as you take off, propelling you forward. The On Cloudeclipse features a brand-new X-shaped Speedboard, which is designed to keep you moving forward as efficiently as possible, eliminating any side-to-side movement during the gait cycle.
A grippy rubber outsole rounds out the shoe, and reviewers were pleased to discover that the oblong-shaped pods don’t pick up any hitchhiking rocks along the ride.
