How to get the right fit

First, don't measure your feet in the morning; feet often swell during the day due to heat and activity. For the best fit, measure your feet at the end of the day.

1. HEEL-TOE LENGTH

Place a piece of paper on the floor with one end against a wall. Stand on the piece of paper with your heel against the wall. Mark the piece of paper where your toes end with a pencil.

Measure from the end of the piece of paper to the mark you created with your pencil and compare the measurement to our sizing chart.
