Two numbers decide your size
Measured foot length, and width across the ball.
Every size we sell is published as the foot length it is cut for, in centimetres, and the internal width across the ball of the foot, in millimetres. So sizing here is a comparison between two numbers rather than a guess between two letters.
Four steps, two minutes.
- 01
Stand on paper, heel to a wall
Put a sheet of paper flat on a hard floor with one short edge against a wall. Stand on it with your weight on both feet and your heel touching the wall. Feet spread under load, so measuring while sitting gives a number that is one to four millimetres too short.
- 02
Mark the longest toe
Mark the paper at the end of your longest toe. That is not always the big toe. Step off and measure from the wall edge to the mark in centimetres, to one decimal place.
- 03
Measure the width across the ball
Still standing, run a tape across the widest part of your foot, just behind the toes. Read it in millimetres. This is the number that decides whether you want a standard or a wide last.
- 04
Do the other foot too
Almost nobody has two identical feet. Use the longer and the wider of the two readings. If the difference is more than five millimetres in length, tell us and we will say which size to take.
The chart
Standard and wide lasts, size by size.
Foot length is identical on both lasts — a wide last is not a longer shoe. Only the internal width across the ball changes, by seven millimetres at every size.
| EU size | Foot length | Standard last | Wide last |
|---|---|---|---|
| 35 | 22.3 cm | 88 mm | 95 mm |
| 36 | 23.0 cm | 90 mm | 97 mm |
| 37 | 23.7 cm | 92 mm | 99 mm |
| 38 | 24.3 cm | 94 mm | 101 mm |
| 39 | 25.0 cm | 96 mm | 103 mm |
| 40 | 25.7 cm | 98 mm | 105 mm |
| 41 | 26.3 cm | 100 mm | 107 mm |
| 42 | 27.0 cm | 102 mm | 109 mm |
Between two sizes
Take the larger size and use a replaceable insole to take up the volume. A 2 mm leather footbed or a 6 mm cushion footbed both change how much room is left inside without changing the length.
Wider than the standard last
If your ball measurement is within 4 mm of the standard width shown, the standard last will settle onto it. Above that, take the wide last rather than a size up: a longer shoe does not become a wider one.
One foot larger than the other
Buy for the longer foot and fit the shorter one with a heel grip, which takes up 3 mm at the collar. It is a smaller compromise than the alternative.
Still not sure which size to take?
Send us your two measurements and we will tell you which size and which last to order. We sell finished shoes in stock sizes — nothing is made to measure — and the reply is a sizing suggestion, not advice about foot health.
