Footwear Size Guide

Find your perfect ONFOOT fit in three easy steps

1. How to Measure Your Foot

How to measure foot size in cm
Step 1. Trace

Stand on a sheet of paper and trace around your foot with a pen held upright.

Step 2. Measure length

Measure from the heel to the tip of the longest toe, in centimetres.

Step 3. Measure width

Measure across the widest part of your foot.

Tip: Measure both feet in the evening when they're slightly swollen, and always go with the larger foot's measurement.

3. Between Sizes?

  • On the border between two lengths: size up for a more comfortable, all-day fit, especially for closed-toe styles.
  • Wide feet: go up one size for extra room across the widest part of the foot.
  • Narrow feet: stay true to size strappy or adjustable styles will accommodate a narrower fit.

4. Style-Specific Fit Notes

Slingback Shoes

Adjustable open heel strap, runs true to size. Between sizes? Size down the strap keeps it secure. Size up only if you have a wide forefoot.

Heels & Pumps

Can feel snug at first. If your measurement sits at the top of a size range, size up half a size; the toe box loosens with wear.

Flat Sandals & Slides

Fit generously. Between sizes? Size down to stop your foot sliding forward.

Ankle Boots & Closed Shoes

True to size. High instep or wide foot? Consider sizing up one size for comfort.
