How to Measure

  • Place a sheet of paper against a wall on a hard floor.
  • Stand naturally, heel against the wall, weight on the foot.
  • Mark the tip of the longest toe (big toe or second toe).
  • Measure wall → mark in cm; repeat for the other foot.
  • Use the larger foot to pick your size.
  • Wear the socks you'll actually use with the shoes.
  • Measure later in the day — feet swell slightly by evening.
  • Whole size only: if you're between sizes, size up.
Removable insoles mean you can add custom orthotics, but sizing should still be based on bare/socked foot length.
