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, when they are at their largest due to swelling.
If you are between sizes, or one foot is bigger than the other, choose the larger size.
Measure your feet every year, as your size can 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 in the thickness you will wear with the shoes
Steps
1. Stand on the paper wearing the socks you will wear with the shoes.
2. Mark the end of your longest toe and the back of your heel. Measure both feet, as their size can vary.
3. Match your longer foot measurement to the CM Size column above. If you are between sizes, choose the larger size for better comfort.
