Footwear Size Guide
Find your perfect ONFOOT fit in three easy steps
1. How to Measure Your Foot

Stand on a sheet of paper and trace around your foot with a pen held upright.
Measure from the heel to the tip of the longest toe, in centimetres.
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.
2. ONFOOT Shoe Size Chart

| 9 | 39 | 24.5 |

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.
