Size Guide
Made for your width.
At SIX INCH™ every style is built on custom molds for women with wider feet — sizes EU 36–44, graded to fit up to an E width.
Foot length sets your size
Measure your longest foot heel-to-toe and match it to the chart below.
Ball girth confirms the fit
Check your girth falls inside the range for that size — that's the wide-fit guarantee.

How to measure
Foot length
- Stand on a flat surface with your heel against a wall, on a piece of paper.
- Trace the outline of your foot with a pen held upright.
- Measure from the tip of your longest toe to your heel, in cm.
- Measure both feet and use the longer one to choose your size.
Ball girth
- Wrap a soft tape measure around the widest part of your foot, just below the toes.
- Keep the tape comfortably snug — not tight.
- Record the measurement in cm.
Fit tip
Use your foot length to find your size, then check your ball girth lands inside the range for that size — if it does, that pair will fit.
Between sizes? Choose the size where both your length and girth sit closest to the chart. Some styles run a touch large or small — check the note on each product page.
