CHAUTFIFTH Size Guide

Find your fit without the chaos.

Measure your foot length and width, compare with the chart below, and use the fit finder for a quicker recommendation.

How to Measure
For Shoes
  • Foot Length (cm): Measure from the back of your heel to the tip of your longest toe.
  • Foot Width (cm): Measure across the widest part of your foot.
  • Narrow (N): Best for slim feet.
  • Standard (M): Best for average foot width.
  • Wide (W): Best for wider feet or anyone who prefers more room.
Step by Step
  1. Place your foot flat on a sheet of paper.
  2. Trace around your foot with a pen or pencil.
  3. Measure from heel to longest toe to find your foot length.
  4. Measure the widest part of the outline to find your foot width.
  5. If you are between sizes, size up for a more comfortable fit.
* Actual fit may vary slightly depending on shoe shape, toe shape, material, strap placement, or whether the style is designed to fit snug.
