NAT'S Size Guide

Finding the right fit is now easier than ever.

We’ve partnered with StrutFit to provide a quick and accurate foot-scanning experience directly through your phone. Use the StrutFit scanner on our product page—or follow the guide below—to determine your ideal NAT’S size.

How Our Sizing Works

The millimeter (mm) size printed on our shoe box and size chart refers to your recommended foot length, not the internal length of the shoe.
For the most accurate result, measure your foot in centimeters or millimeters, then match it to the chart to find your corresponding EU, US, or UK size.

If you need help, reach us anytime at support@natsfootwear.com — our team is happy to guide you.

Size Conversion Chart

(This chart follows European footwear conversion standards; variations up to ±2mm are normal.)

How to Measure Foot Length (If Not Using StrutFit)

1、Tape a sheet of paper onto a hard, flat floor to prevent slipping.

2、Stand naturally on the paper with your full weight evenly distributed.

3、Have someone mark the tip of your longest toe and the back of your heel.

4、Step off and measure the distance between the two marks — this is your foot length.

5、Measure both feet and use the longer measurement.

6、If you fall between sizes, choose the larger size for extra comfort, or the smaller size for a more secure, performance-oriented fit.
