The full-length dual-arc reinforced carbon fiber plate is scientifically engineered for sprinting. Its arched forefoot structure enhances push-off rebound and propulsion, while the reinforced arch provides stable support. Combined with the lightweight HiFoam MAX supercritical high-resilience midsole and full-length H-PEBAX elastic outsole, it accelerates energy return and delivers explosive power for faster sprints and bursts of speed.

Size Measuring Guide
A perfect fit for your ultra-marathon running shoes is important for comfort and performance. Follow these tips to measure your foot size at home:
General Tips:
- Measure your feet at the end of the day as they're at their largest due to swelling.
- In between sizes? One foot is bigger than the other? Take the larger size.
- It's best to measure every year. Your size could change over time.
What You'll Need:
- A piece of paper larger than your foot,
- A pen or pencil,
- A ruler or measuring tape,
- Socks of the thickness you'll wear with the shoes.
Steps:
- Stand on the paper in the socks you'll wear with the shoes.
- Use the pen or pencil to mark the end of your longest toe and the back of your heel. It's important to measure both feet as their size can vary.
- Match your measurements to our size chart to find the best fit. If you're between sizes, we suggest choosing the larger size for better comfort.
High-Strength Hi-FIBER Woven Upper
Crafted with HIRACER Hi-Fiber upper material, which is lighter than human hair, it features special weaving to create breathable micro-holes,delivering enhanced breathability, toughness, and durability. With reinforced support structures and a seamless fit, it creates a tech-forward, breathable upper.Compared to CP2 material, the upper strength is significantly improved.·20% better fit than MONO yarn·30% better breathability than MONO yarn·20% lighter than traditional mesh·30% higher strength
HiFoam MAX Supercritical Sheet High-Resilience Foam
Crafted with all-new ATPU supercritical sheet pressing technology, it reduces the weight of the midsole while delivering exceptional cushioning and resilience. It boosts energy return efficiency for explosive rebound.Paired with the dual-arc carbon fiber plate structure and full-coverage carbon fiber outsole, it delivers explosive power for sprint acceleration and bursts of speed.
Full-Length Dual-Arc Reinforced Carbon Fiber Plate
Full-Length Dual-Arc Reinforced Carbon Fiber PlateThe full-length carbon fiber material is scientifically placed to meet the demands of sprinting. An arched carbon fiber structure is designed in the forefoot to deliver greater push-off rebound and propulsion, delivering accelerated energy return to power you forward at blistering speed.The reinforced arched structure at the arch of the foot enhances and stabilizes arch support.
Full-Length H-PEBAX Crystal-Clear Nylon Elastic Outsole
The crystal-clear nylon elastomer material, through precision injection molding, forms a uniform special structure, delivering superior energy return efficiency and faster rebound to continuously power your feet.The scientifically distributed 6-stud design, paired with wave patterns and triangular crystal studs, enhances grip and stability.
These feel super stable on foot, and the propulsion is really impressive. The gold color also looks awesome and really stands out!
