Our latest collaboration with Kiprun – Decathlon’s specialist running brand – brings RHEON™ adaptive polymer technology to the Run 900 Ultra Shorts: a high-performance short built for runners who demand more from every stride.
Lab testing confirms an 8.7% reduction in quadricep vibration compared to the previous Kiprun model – measurable proof that smart material science translates directly into running performance.
At rest, RHEON™ is soft and flexible. As movement intensifies, it stiffens instantly, stabilising the surrounding muscles when they need it most. The moment this force passes, RHEON™ returns to its natural flexible state.
In the Run 900 Ultra Shorts, RHEON™ is integrated into the quadricep zone – the area that absorbs the most mechanical stress during running. The result is targeted, dynamic muscle support that activates with movement.
Traditional compression garments apply constant, uniform pressure across the muscle group. This can cause discomfort and be overly restrictive, a trade-off runners often accept without realising it.
Because RHEON™ activates with specific movement, the garment remains comfortable between strides. Support is delivered dynamically meaning no constant compression, no restriction and no compromise.
The Run 900 Ultra Shorts are designed for runners who train across multiple disciplines. Whether you’re:
You’ll get the same performance benefit whether you’re descending a mountain or hitting your tempo pace on a road loop.
The Run 900 Ultra Shorts represent the latest chapter in an expanding collaboration between RHEON and Kiprun, built on a shared commitment to performance-led product development, this partnership brings together Kiprun’s deep understanding of the runner’s body and RHEON’s expertise in adaptive material technology.
Our latest launch with Kiprun is part of a wider partnership with Decathlon to make RHEON‘s high performance technology widely available and easily accessible to both athletes and everyday users.
