【On】This year, I want to finish! I've found the "partner" for runners aiming for a sub 4.5.
Swiss sports brand "On" has launched a new racing shoe. With this partner, a sub-4.5 is not just a dream!
Racing shoes for full marathon runners

It's no exaggeration to say that marathon times are influenced by shoes, which is why choosing a "partner" is crucial. The author, who was looking for a pair of shoes for the competition, found the latest model from the Swiss sports brand "On" called "Cloudboom Max."
This shoe is designed for runners who want to finish a full marathon in 4 to 4.5 hours and want to showcase the results of their training!

High cushioning

With more support and cushioning than elite runners' "super shoes" that pursue speed, it also maintains solid rebound. By employing the brand's top-level high rebound foam, it optimizes the shape of the midsole for a wide range of runners.
Looking at the detailed design, the heel measures 40mm, the toe 32mm, and the drop is 8mm. This design provides solid stability and propulsion for runners aiming for sub-4.5 hours.
Stability and Support

Another secret is the fiberglass "Speedboard." The nylon plate infused with 8% fiberglass supports heel strike running and enhances comfort during long-distance runs. Thanks to the breathable and well-fitting mesh upper, it feels great until the finish line.
