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.

HI-FIBER High Strength Fiber Upper
Crafted with HI-FIBER special HI-strength yarn, it forms breathable micro-holes via a specialized weaving process for enhanced breathability, toughness, and durability. Built-in crystal-clear supportive reinforcement ensures a seamless, snug fit. Combined with an integrated flywire tongue, it creates a technologically advanced, highly breathable upper.
The Full-Palm Double-Arched "Golden" Propulsion Carbon Plate
According to the movement requirements of the front and back palms, 8 layers of multi-directional double-arched carbon fiber structure materials are laid. Compared with the previous generation of arched carbon plates: the "golden" double layer increases the double-arched rebound and compression deformation of the carbon plate, making the carbon plate more tough: Kevlar is laid at the arch of the foot, and reinforcing ribs are set to increase the rigidity of the arch of the foot, enhancing running stability. Super rebound and super stability, comprehensively upgraded.
HiFoam Max Double Layer Board Foaming Midsole
Crafted with an all-new HI-performance supercritical sheet pressing process, it reduces midsole weight, delivers exceptional cushioning and resilience, boosts energy return efficiency for ultra-responsive bounce. Combined with a dual-arch carbon plate structure and full-coverage carbon fiber outsole, it provides sustained energy support for marathons.
AGCS Wet Ground Anti Slip and Wear-Resistant Outsole
The outsole of the All Ground Control System is made of polyurethane material, delivering stronger grip, superior slip resistance on wet surfaces and excellent wear resistance.
