Every component of the RS-9000 has been developed and tested in the laboratory to minimize weight—126 grams—without compromising efficiency or performance.
If there is a clear example of the brand’s technical evolution, it is the new RS-9000 model. After 60 years of experience in the sports market, Joma is launching this powerful sneaker, aiming to revolutionize the history of high-performance running footwear.
The RS-9000 was born with a clear goal: to be the lightest competition shoes on the market. An ambitious bet on innovation, speed, and efficiency, through which Joma seeks to reach the ultimate in lightness. And they have succeeded: they weigh only 126 grams.
But none of this would have been possible without the meticulous development process. The brand’s R&D+i team worked on every detail to ensure each part of the sneaker is characterized by maximum lightness. At the same time, efficiency and performance were evaluated in laboratory tests under extreme conditions of exertion.
Ultralight technology for achieving your best performance
The development of this new model focused on aspects such as running efficiency, performance, and, above all, reducing weight to reach 126 grams.
- Minimalist, ultralight, and breathable upper made with nylon thread reinforced with polyamide, providing optimal moisture management and keeping the foot at a constant temperature even in extreme conditions.
- 8mm drop midsole with LIGHT REACTIVE technology in injected Pebax, delivering maximum responsiveness and impact absorption without sacrificing lightness.
- Carbon plate that boosts energy return and stabilizes the stride at high speeds, flexible enough to protect the runner while allowing refined technique.
- CPU outsole, abrasion-resistant yet lighter than rubber, ideal for asphalt and non-aggressive terrain.
