Find your size

Measure both feet in cm (the longer one decides) and enter them below. Every size lists the exact insole of its handmade last — pick the one just above the longer foot.

Measure both feet. Most people have one foot slightly longer than the other — go by the longer one. Your size is the first one whose insole is longer than that foot — each size lists the exact insole of its handmade last. If the fit isn't right, returns are free for 30 days.

EU is the number on the box (your true size). US/UK are standard references — pick your system above. The cm column is the shoe's inner (insole) length.

How to measure

  1. Step 1

    Late in the day, stand on a sheet of paper — feet are at their largest then.

  2. Step 2

    Mark your longest toe and the back of your heel.

  3. Step 3

    Measure the gap, then repeat for the other foot and use the longer one.

  4. Step 4

    Pick the Insole just above your foot — leave ~0.5 cm for toe room.

Size Guide

Measure both feet first, then match. Most people have one foot slightly longer than the other — the longer foot decides your size. Every pair is built on a handmade last; the table lists the exact inner (insole) length of each size. Match your longer foot to the closest insole above it. EU is the number on the box; US and UK are standard references.

How to measure your feet

  1. Stand on a sheet of paper with your weight even on both feet.
  2. Mark the tip of your longest toe and the back of your heel.
  3. Measure the distance between the marks in centimetres.
  4. Repeat for the other foot — most people's feet differ slightly.
  5. Pick the size whose insole length is just above your longer foot.

Between sizes or unsure? Use the Find my size tool above or on any product page — enter both measurements and it picks the size for you (and notes them on your order automatically). And if the fit isn't right, size exchanges are free within 30 days.
