What's Happening
On, the Swiss sportswear brand, has officially entered competitive hybrid fitness racing with the launch of the Cloud X Tempo Pro, its first dual-purpose shoe built for the demands of the sport. The announcement, made June 15, also includes the signing of two athletes to anchor On's push into the category: HYROX standout Alexander Roncevic and former two-time Obstacle Course Racing World Champion Ida Mathilde Steensgaard.
Roncevic is the centerpiece. A former HYROX World Champion and current double world record holder in Men's Pro Singles, he became the first athlete ever to break the 52-minute barrier with a 51:59 finish in Warsaw, and he also holds the Men's Pro Doubles world record. On co-developed the shoe with him through months of lab testing and biometric analysis, and he set both of those world records while racing in a prototype of the Cloud X Tempo Pro.
The shoe is engineered to handle the sport's split demands of fast running and heavy functional stations. It features a full-length carbon Speedboard plate and a rocker shape for propulsion, Helion HF hyper foam for lightweight cushioning, a Missiongrip outsole for traction on sleds and transitions, and a supportive midfoot cage with an integrated strap to lock the foot down during movements like sled pushes and lunges. The Cloud X Tempo Pro launches globally in August 2026 for CHF 300 (roughly $375) at on.com and select retail partners.
Why It Matters
This is On planting a flag in the fastest-growing format in fitness. HYROX has exploded from a niche European event into a global phenomenon, and the footwear brands have noticed. On entering with a dedicated carbon-plated racing shoe, rather than just marketing an existing trainer as HYROX-friendly, signals that it sees hybrid racing as a category worth building specific product and signing specific athletes for.
The athlete strategy is the sharpest part of the play. By co-developing the shoe with the actual world record holder and having him break records in the prototype, On gets a marketing story no competitor can match: the fastest man in the sport helped build it and won in it before it ever hit shelves. That is On's classic athlete-first product playbook, applied to a sport where credibility with the core competitive community drives what the mass market buys.
Bigger Picture
The HYROX shoe war is officially on. Nike and Puma have already moved into the space with dedicated hybrid offerings, and On joining with a premium, record-validated entry confirms that every major performance brand now sees hybrid racing as a strategic battleground rather than a passing trend. For a sport that barely existed in the mainstream a few years ago, having the biggest footwear names compete to outfit its athletes is a marker of how mainstream it has become.
It also fits On's broader trajectory as a brand pushing aggressively beyond its running roots. On has expanded into tennis, training, and outdoor in recent years, leaning on premium pricing and visible technology to justify its position at the high end of the market. At roughly $375, the Cloud X Tempo Pro is firmly a premium product, and it reflects On's bet that serious hybrid racers, like serious runners, will pay top dollar for a shoe with genuine competitive pedigree. Whether that pedigree translates to everyday gym-goers, who make up the bulk of HYROX's growth, is the question the August launch will start to answer.
