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.

Breathable High-Strength Woven Upper
Using a new jacquard weaving technique, the upper offers a finer, more textured feel with greater resilience and flexibility than traditional large-mesh uppers. Its streamlined, foot-hugging design and lightweight, breathable construction help keep feet comfortable and dry throughout wear.
HiFoamTPEE Ultra-Cushioned Midsole
The midsole is produced through a specialized HiFoamTPEE foaming process. This highly shock-absorbing material reduces weight, resists tearing, and delivers exceptional cushioning with resilient rebound. Ideal for everyday wear, post-run recovery, and commuting.
Wide Forefoot Design
The wide forefoot design allows natural toe splay, helps distribute landing forces, and reduces pressure and pinching. It supports a stable, comfortable ride with excellent breathability, helping long-distance runs feel easier.
One-Piece Molded Anti-Slip Outsole
Made using a one-piece compression-molding process, the outsole delivers enhanced traction and improved slip resistance on wet surfaces, supporting more secure footing during running and other athletic activities.
Stable Support for Training and Everyday Life
Whether for gym training, warm-up runs, or everyday wear, Flywire technology enhances overall support and durability while providing a secure, locked-in fit. The lightweight construction minimizes weight underfoot, helping every movement feel easier.
From the first kilometer and beyond.
The HiFoamTPEE midsole delivers cushioning and energy return with every step, giving PASA a soft, cloud-like ride with lasting comfort.
Lightweight comfort, not just for running.
The lightweight construction combines with the Flyline knit upper to deliver breathable comfort and a fresh feel during summer workouts and everyday wear.
