Hiking, Backpacking & Trail Size Guide

Measure your foot once in millimetres, then find that number in the left column of the women's, men's or kids' chart and read straight across for UK, EU and US sizes. The numbers already include the recommended toe room, so nothing needs to be added. Sizes are not standardised between brands, and a narrow shoe reads smaller than a wide one — so treat the chart as your starting point and always check the fit that suits your own foot.

Two US labels, one foot. Several women's lines — hiking, all-terrain, everyday, cold-weather and tactical styles with injected soles — are labelled half a size larger in US sizing than trekking and mountaineering boots. A 252 mm foot is a US 8 in trekking models and a US 8.5 in injected-sole styles. Order by the column that matches the style you are buying.

Start at your street size. Men's boots are built on UK lasts, so the UK number is the true one and the US number is a conversion (US = UK + 1). Order the same size as your everyday shoes, wear the socks you plan to hike in, and if your measurement lands between two rows, take the larger size — a boot that is slightly too long still fits, one that is too short does not.

Kids' & Youth Footwear

Growing room is already in the number. Kids' sizes include 12 mm of growing room, and the US run goes 5.5K to 13K before restarting at 0.5 to 3. Measure both feet standing up and use the longer one — feet grow fastest between sizes, so re-measure before each new season rather than guessing from age.

Socks

Sold in odd EU sizes: 35, 37, 39, 41, 43, 45, 47

Swipe the table sideways to see every size system.

Sock size (EU)	US Women's	US Men's
35–36	4.5–5	—
37–38	6–7	5–6
39–40	7.5–8.5	6.5–7.5
41–42	9–10	8–9
43–44	10.5–11.5	9.5–10.5
45–46	—	11–12
47–48	—	13–14

Match your boot, not your shoe. Read the sock size from the boot size you actually wear on the trail — if your boots are a UK 8, take the sock size covering that EU range. Socks sold in odd EU numbers run every other size, so a 37 covers EU 37–38 and a 39 covers EU 39–40.

Width & Fit

Width letters, last types and how much toe room is built in

Fit	Women's width letter	Men's width letter
Narrow	A	C
Medium	B	D
Wide	C	E / EE

Last	Forefoot volume	Who it suits
Narrow (S last)	Less than a standard last	Slimmer feet
Standard	Medium — used on most styles	Most feet
Wide (W last)	More across the forefoot, plus an expanded toe box and extra room around the arch and instep	Bunions, flat feet, fallen arches, high insteps

Toe room is built in. Adult charts already include 15 mm of toe room and kids' charts 12 mm, so match your measured foot length straight to the chart without adding anything. Try boots on in the afternoon, when feet are slightly swollen, and wear the socks you plan to hike in — that combination, not the number on the box, decides whether the fit works.

How to Measure at Home

Measure standing up. Put a sheet of paper against a wall, stand on it with your heel touching the wall, mark the tip of your longest toe and measure the distance in millimetres.
Use the longer foot. Feet are rarely identical, so measure both and work from the bigger number in millimetres.
Find the row. Locate your measurement in the left column of the women's, men's or kids' chart, then read across for the UK, EU and US size.
Adding nothing on top. The recommended toe room is already included. If you land between two rows, take the larger size.

Fit Notes

Street size first: the general rule is to order the same size as your everyday shoe, in the socks you will actually wear.
UK is the true size: these boots are built on UK lasts, so UK is the reference and US and EU are conversions rather than separate fits.
Women's half-size gap: injected-sole styles (hiking, all-terrain, everyday, cold-weather, tactical) are labelled half a size larger in US sizing than trekking and mountaineering boots.
Between two sizes: size up — descending steep ground pushes the foot forward, and a boot with spare length stays comfortable where a tight one blisters.
Wide or narrow feet: a W last adds forefoot volume and toe-box room; an S last suits slimmer feet. Both are noted on the product page when a style offers them.
Heavy socks or liners: if you add a liner sock or plan a winter trip, check the next size up before committing.
Kids: 12 mm of growing room is already in the chart, so buy the size that matches the measurement rather than a size ahead.
Try them in the afternoon: feet swell during the day, so an afternoon fitting is closer to a full day on the trail than a morning one.

Shoe sizes are not standardised between brands, and sizing can vary slightly from category to category — the shape of a last also changes how large a boot feels. This guide is for sizing footwear and socks only, and all feet are unique, so a shop fitting remains the surest check.
