Size Charts

IMPORTANT Be advised all measurements shown in the size charts are listed in millimetres and refer to all current models purchased after 2015.

Last Length is the internal length of the shoe in millimetres. We recommend at least 5mm gap between your longest toe and the front of the shoe. If in doubt, go up to the next size in the chart.

Foot Length Range is our recommendation for the length of foot (without socks) suitable for each size. As you can see, there will always be at least 5mm different between the longest foot length in the range compared to the corresponding Last Length measurement.

Standard, Wide and Double Wide Range refers to the width recommendations for each width option. This is should be taken using your widest foot, measured at the forefoot and if at the upper limit of a width, go up to the next width option.
