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.

Diagonal Fine Lenow Hi-Fiber Upper
Constructed with fine lenow Hi-Fiber yarns. Diagonal weaving creates tiny breathable pores for enhanced air permeability, toughness and durability. Built-in reinforced support structure delivers a seamless fit.
Full-Length Power Capsule
Built on HIRACER custom supercritical elastomer, it innovatively features a full-perimeter high-barrier polymer nano-film wrap. Nano-scale dense airtightness locks in high-purity nitrogen, drastically reducing performance degradation caused by gas loss. Rigid edge confinement restricts lateral material deformation to markedly boost rebound efficiency and support stability.
Adaptive Strap Technology
Equipped with the AP-FITx2 dynamic lockdown structure for balanced force distribution. It automatically adjusts tension as your foot deforms during running. It delivers all-around uniform instep coverage to prevent localized pressure points. With controllable tightness, it perfectly fits both wide and narrow feet, securely locking the foot in motion while balancing containment and freedom of movement.
AGCS All-Weather Wear-Resistant Anti-Slip Outsole with DSP/KPU Traction Particles
The All Ground Control System (AGCS) outsole is made of polyurethane, delivering enhanced traction, superior wet-grip performance and outstanding abrasion resistance.
