MEN'S FOOTWEAR
HOW TO MEASURE
To find your foot measurement closely trace your entire foot onto a piece of paper and measure from heel to toe. If your measurement is between chart numbers, we recommend sizing up. Be sure you’re putting your full weight on your foot while tracing. Please note: for the best results, measuring later in the day is recommended.
