Size guide

Measure your foot, do not guess. Sizing differs from one model to the next — the length below is what decides, not the number you usually buy.

Heel to longest toe

These styles can fit slightly smaller than standard sizing. If you are between sizes, choose the larger size.

How to measure your foot
  1. Put a sheet of paper against a wall and stand on it, heel to the wall.
  2. Mark the tip of your longest toe.
  3. Measure from the wall to the mark.
  4. Measure both feet in the evening and use the longer one.

Lengths are measured by hand — allow about 0.5 cm of variation. Your own measurement always takes priority over a size label.
