Shoe Size Guide

Size inclusivity is one of our core values. We collected and analyzed foot tracings from thousands of customers and combined that data with a study of 1.2 million 3D foot scans to develop a proprietary fit algorithm that encompasses 32 length sizes and 4 width sizes.

To verify your size, we recommend tracing your foot (or having someone else trace your foot) while standing. Measure the length of your foot from the tip of your big toe to the end of the heel, then measure the width at the widest part of the ball of your foot.

Tips + Notes:

Try to trace with a thin pen or pencil held vertically and tightly to your foot, and visually verify that the tracing is neither bigger nor smaller than the outline of your foot. If your feet are slightly differently sized (which is common), use the measurements of the larger foot - or if they are substantially different, trace each foot and let us know each size in the notes section at checkout so we can make your pair in two different sizes. 

If you have a thin ruler you can stand on, that works as well. Just make sure that the very back of your heel bone aligns with 0 for the length measurement.

If your feet fall outside our 128 available sizes, feel free to mail your tracings to us and we can chat about making a completely custom pair for you! An additional customization fee of $100 may apply.
