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:
  1. Stand on the paper in the socks you'll wear with the shoes.
  2. 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.
  3. 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.
