The latest innovation from , CloudTec Phase™ uses Finite Element Analysis (FEA) to simulate the interaction of the shoe's components. With that insight, On was able to create the optimal midsole design to allow for seamless weight transfer front-to-back. Visually this comes across in the seemingly random angle of the CloudTec cutouts, which are precisely laid thanks to the FEA research. On the Cloudeclipse, On has managed to develop a double-layered version of CloudTec Phase™ for the ultimate cushioning experience.

As with most On Running footwear the uppers are kept clean and simple. In this instance the engineered mesh dominates with areas in need of reinforcement strengthened with thick stitching to ensure a more durable junction.
