Frequently Asked Questions
🦶 How to Measure Your Feet
1. Trace Your Foot
The most accurate method for home measurement:
- Place a piece of paper on the floor against a wall.
- Stand on the paper with your heel against the wall.
- Hold a pen vertically (90°) and trace your foot outline.
2. Measure Length & Width
- Use a ruler to measure the length from the heel line to your longest toe mark.
- Measure the width at the widest part of your foot trace.
- Pro Tip: Subtract 0.2 inches (5mm) from length to account for the pencil width.
👟 Fit Check: The Thumb Test
Is it the right size?
- There should be about a thumb's width of space between your longest toe and the end of the shoe.
- The heel should fit snugly without slipping.
- The widest part of your foot should align with the widest part of the shoe.
