Size Guide

Find your perfect fit. Most of our Dyma-tex® waterproof knit shoes use full US sizes. The Tidal Sneaker and Market Flat are also offered in half sizes. Measure both feet and use the longer foot to find your US size—when in doubt, size up for a more comfortable, all-day fit.

Step 1
Stand on a sheet of paper with your heel lightly touching a wall.

Step 2
Mark the tip of your longest toe, then measure from the wall to the mark.

Step 3
Repeat for the other foot and use the larger measurement with the chart.

* If you are between sizes, we recommend sizing up for a roomier, more comfortable fit.
* Our Dyma-tex® knit upper stretches gently with wear; actual fit may vary slightly by style.
