He enters the world of HYROX competition with the Cloud X Tempo Pro model - the brand's first dedicated hybrid competition shoe, combining a carbon plate, responsive foam and stability for exercises such as sled pushes, lunges and wall ball throws.
HYROX is no longer just a weird obsession of people who voluntarily pay to push sleds and throw balls at walls while running. It has become one of the fastest-growing fitness competition formats, a kind of marathon for a generation that wants to have the lungs of a runner, the legs of a weightlifter, and enough self-respect to post it all on Instagram.
So it's no surprise that the battle is moving to the feet. After Puma, Nike and Reebok, Swiss brand On is now entering the ring – and with a model On Cloud X Tempo Pro, the brand's first purpose-built hybrid racing shoe. It's a shoe that aims to solve the fundamental problem of HYROX: how to be fast on eight cross-country tracks, but at the same time stable enough when your body realizes during the sled push that weekend training wasn't enough.
Why On Cloud X Tempo Pro is important
A classic running shoe is great as long as you're running straight. A classic fitness shoe is great as long as you're not running five miles. HYROX requires both: speed, responsiveness, traction, stability, and enough security to keep your foot from floating away like a tourist on a stand-up paddleboard without balance.
The Cloud X Tempo Pro is therefore not just another version of the existing Cloud X model. He presents it as a dedicated shoe for hybrid fitness competitions. At its core, it has carbon Speedboard, which is supposed to help with a more explosive push-off, and Helion HF foam, a technology that On uses in his faster running models. It also adds a rocker sole geometry designed for faster stride transition during the running portions of the race.
But the real difference is that the shoe didn't blindly adopt the logic of road running supershoes. With HYROX, it's not enough to just fly across the surface. You have to stop, grab a sled, push, pull, kneel, jump, carry, throw, and then start running again. That's why the Cloud X Tempo Pro has a reinforced midsole, a supportive construction around the foot, an integrated strap for better foot grip, and a Missiongrip outsole for better ground contact.
Developed with a recorder, not just in the boardroom
He developed the shoe with Austrian HYROX athlete Alexander Rončević, who set a world record with a time in Warsaw this year. 51:59,37 and became the first competitor to complete the HYROX under 52 minutes. This is important because with a product like this, the difference is not in a nice marketing slogan, but in whether the shoe still holds the foot where it needs to be, even at the height of fatigue.
Rončević has already used the prototype in competitions, and now he's transferring this technology to a production model. In theory, this means a shoe that's not just for a nice warm-up in front of the mirror, but for an actual race, where every second is lost between running pace, transition to the station, and stability during functional exercises.
Competitors? Puma is already deep in the game
He doesn't come into this space empty-handed. Puma has a strong relationship with HYROX and already has a very clear strategy in this category, while the Nike Metcon remains one of the most recognizable choices among athletes who need a stable training shoe. The difference is that with the Cloud X Tempo Pro, He isn't just targeting the gym, but a new niche: competition hybrid shoe, which must be almost a running supershoe and almost a fitness armor at the same time.
This is also why it will be interesting to see how it performs in practice. A carbon plate can be great for running, but combined with stability for sled pushes and lunges, it requires very precise balance. Too much running feel and the shoe will be unstable. Too much fitness stiffness and an eight-kilometer run will be a penalty, not an advantage.
Price and market launch
On Cloud X Tempo Pro will be launched globally in August 2026, with an official price of 300 Swiss francs, which at the current exchange rate means approximately 325 eurosThis puts it in the class of serious competition shoes, where the buyer is not just paying for a logo, but for a promise that the shoe will perform at the moment when the body is already considering surrender.
Will the Cloud X Tempo Pro become the new holy grail for HYROX runners? It's too early to tell. But one thing is clear: hybrid fitness has become big enough to get its own specialized shoes. And when brands start sending carbon to the gym, we know the game has changed. Burpees have clearly become serious enough to require Swiss engineering.
