How to Measure Your Foot
Stand on a piece of paper and trace your foot outline. Measure from the back of your heel to the tip of your longest toe. Always measure both feet and use the larger measurement.
Feet swell slightly throughout the day, so measure later in the day. Wear socks you plan to use with your flats for most accurate results.

Fit Tips
Our flats feature plush cushioned insoles. If you fall between two sizes, pick the larger one for greater comfort.
The soft insole will gradually shape to your foot after a few wears.
For wide feet, we recommend sizing up for a relaxed fit.
