Our shoes are unisex. Please refer to the size chart below to find your size.

How to Measure Your Feet

1
Stand on paper with your heel against a wall.
2
Mark the tip of your longest toe.
3
Measure the distance in inches or cm.
4
Use your larger foot's measurement.
Pro Tip: The CM and INCH columns are your actual foot length, not the shoe. Do not add wiggle room — that is already built in. Match your measurement to the row, and if you are between sizes, size up.

Fitting Notes

  • Wide toe box designed for natural toe splay
  • Between sizes? We recommend sizing up
  • These US sizes are matched to this style’s real measurements, so they may differ by half a size from other brands — trust the CM column
  • Measure feet at the end of the day when they're largest
  • Always use your larger foot's measurement
