Kenyan marathoner Barnabas Kiplimo clinched victory in the 2025 men’s edition of the Khon Kaen Marathon in Thailand. While it’s no surprise for Kenyan runners to dominate long-distance events, the manner of Kiplimo’s win has captured global attention.
Revolutionizing Running Footwear
Kiplimo made history by winning the race wearing the world’s first carbon-plated running sandal, the Nirun, designed by Thai brand VING. This innovative footwear has redefined performance running by introducing a minimalist yet high-tech sandal built for speed and comfort.
The Nirun is marketed as the “world’s first super sandal,” designed to simplify the footwear industry while maximizing performance. Its standout features include:
- A full-length carbon plate embedded in the foam midsole, enhancing cadence and responsiveness.
- An upper and midsole made of proprietary foam for a lightweight, minimalist feel.
- A traditional thong-style flip-flop design with a foam heel strap for added security, akin to a Croc.
Performance Validation
Skepticism around minimalist footwear has been prevalent, but Kiplimo’s performance at Khon Kaen validated the Nirun’s potential. He improved his personal best marathon time by eight minutes, an achievement that underscores the sandal’s innovative design and capabilities.
Pushing the Boundaries of Running Technology
VING’s creation of the Nirun highlights the ongoing evolution of running technology, challenging conventional norms. The brand aims to “simplify the footwear industry” while empowering athletes to perform at their best. Kiplimo’s victory is a testament to how unconventional innovations can drive elite performance.
A New Era in Long-Distance Running
Barnabas Kiplimo’s win not only adds to Kenya’s storied history in long-distance running but also opens new conversations about footwear innovation in competitive sports. The Khon Kaen Marathon has become a landmark event for introducing a paradigm shift in how athletes approach marathon footwear.
