Fit tip: Boots fit true to size. Half sizes share the same footbed as the full size — the extra leather in the upper adds width, not length. Wide feet? Go a half size up.

Women’s Safety Sizes

Dedicated women’s fit on safety work boots. Find your row by measured foot length (mm) — do not convert from the unisex chart.

6	220	36
6.5	220	36.5

Fit tip: Safety boots should feel snug over the instep with no heel slip. As with all our leather boots, the upper stretches slightly with wear — never lengthwise.

Kids & Youth Sizes

Measure your child’s foot in millimetres (both feet, use the larger) and match the row below. Fit by measured foot length, not by age.

Youth 1	8	203	33
Youth 2	8 ⅜	212	34.5
Youth 3	8 ⅝	220	35.5

Fit tip: Every kids’ style includes removable footbeds, so you can fine-tune the fit as feet grow. Leave about a thumb’s width of growing room in front of the longest toe.

How to Measure & Fit

Three quick steps to your perfect pair:

Measure foot length. Stand barefoot on a sheet of paper and mark where your longest toe ends. Measure in millimetres from the back of your heel to the tip of your big toe. Repeat with both feet and use the larger measurement to find your size in the chart.
Need more width? Choose a half size up. Half sizes use the exact same footbed as the whole size — they simply add extra leather in the upper for wider feet.
Try them on properly. Try boots on standing up, wearing the socks or stockings you plan to wear, on a carpeted surface to protect the soles.

Fit Notes

Boots fit true to size. The leather stretches and molds to your feet over time, but never lengthwise.
When trying on, there should be a slight give in the heel and about half a centimetre (≈ ¼ inch) of space between your longest toe and the front of the boot.
The leather will stretch slightly over the instep with repeated wear.
Classic pull-on styles run slightly wider than the original last and include extra insoles to fine-tune the fit.
Dress styles have a slightly longer fit — some wearers go down a half or full size in these.
Between sizes or prefer a roomy fit? Size up. Prefer a snug fit? Stay with the smaller size.

Why the heel slips at first: A little heel movement on day one is normal — it disappears as the leather flexes and molds to your foot within the first few wears.

Size conversions are provided as a guide only. Fit can vary slightly between lasts, leathers and lacing systems. If you are between sizes, we recommend measuring your feet and choosing by foot length (mm).
