Fit & Sizing

Size Guide

Our footwear is built to the European size standard. Measure your foot, match the numbers to the charts below, and you are set.

Women's Footwear

Half sizes and wide fits are available in most styles. Not sure? Match your foot length first, then use girth to fine-tune the width.

Women's footwear size chart
US Size	EU	UK	Foot Length (mm)	Foot Length (in)	Girth (mm) R / W
5	35	2.5	221.7	8.7	218 / 226

10.5	42	8	268.2	10.6	246 / 257
11	43	8.5	275.0	10.8	252 / 259

R = Regular fit · W = Wide fit — the wide last adds roughly 8 mm of girth at the same foot length. Half sizes sit between the whole sizes shown.

Men's & Unisex Footwear

Unisex styles follow the same European last. The conversions below use men's sizing.

Men's and unisex footwear size chart
EU	US (Men)	UK (Men)	Foot Length (mm)	Foot Length (in)
39	6.5	6	248.4	9.8
40	7	6.5	255.0	10.0
41	8	7.5	261.6	10.3
42	8.5	8	268.2	10.6

44	10	9.5	281.6	11.1
45	11	10.5	288.3	11.3
46	12	11.5	294.9	11.6

Unisex sneakers and slip-ons are cut from the same last as our women's styles — check the foot length column when you are between size systems.

Kids' Footwear

Kids' styles run from EU 30 to EU 37. Always go by foot length — children's feet grow fast, so size up when in doubt.

Kids' footwear size chart
EU	UK	US	Foot Length (cm)	Foot Length (in)
30	11.5	12.5	18.4	7.3
31	12	13	19.1	7.5
32	13	1	19.7	7.8
33	1	2	20.6	8.1
34	1.5	2.5	21.0	8.3
35	2.5	3.5	21.9	8.6
36	3	4	22.2	8.7
37	4	5	23.2	9.1

Kids' UK and US conversions are approximate. Foot length in centimetres is the most reliable guide across age groups.

How to Measure

Measure at the end of the day, when your feet are at their largest — and always measure both.

Trace your foot
Stand on a sheet of paper with your heel against a wall, then trace the outline of each foot while standing.
Measure the length
Measure from the heel to the tip of your longest toe. Use the longer of the two feet.
Measure the girth
Wrap a tape measure around the widest part of your foot, across the ball, and note the circumference.
Match and confirm
Find your foot length in the chart, then check the girth column to decide between a regular and a wide fit.

Getting the Fit Right

A few things worth knowing before you choose.

Between two sizes? Take the larger one — or go up a half size for a roomier feel.
Pointed and tapered styles can feel snug at the toe. A half size up keeps the toes comfortable.
Wider feet: choose the wide fit, which adds about 8 mm of girth without extra length.
Measure late in the day. Feet swell slightly over the course of the day and during warm weather.
Stand while measuring and use your larger foot — most people have one foot slightly bigger.
Knit uppers give a little with wear. Structured leather styles hold their shape, so size them honestly.
