Our foot pocket sizing is true to actual foot size in millimeters / inch. For use with up to 3mm neoprene socks we advise selecting the foot pocket size which corresponds with your actual foot size.

For use with thicker (3~5mm+) neoprene socks, we advise selecting one size larger than your actual shoe size.

To determine which foot pocket size is right for you, please refer to our universal shoe size conversion chart.
