Accurate measurement = perfect fit. Takes 2 minutes. All you need is a sheet of paper, a pen, and a tape measure or ruler.
1
Paper against a wall On a hard floor, push a sheet of paper against a wall. Stand on it with full weight, heel touching the wall, in the socks you'll wear with boots.
2
Mark your longest toe Hold the pen straight up (not angled) and mark the tip of your longest toe. Easier with a helper.
3
Measure the distance Measure from the paper's wall edge to the mark in inchescm. Do both feet, then set the Size Finder above to the larger number.
Pro Tips
Measure in the afternoon or evening - your feet swell throughout the day. This gives you the most accurate size for all-day comfort.
No tape measure or ruler? Print our measuring guide, stand on it, and read your size straight off the page. Print at Actual size (100%), never βFit to pageβ, then do the 10-second check printed on the sheet (you need one spare sheet of paper). If the check fails, donβt use the print: a shrunk print reads 1 to 2 sizes too big. Printing from a phone often canβt do Actual size, so use the tape method above instead.

What's Different About Wide Fit?
Wide isn't a bigger boot - it's a wider one. Same length, same toe box height, more room where wide feet actually need it:
+0.51 in+13 mm ball girthMore circumference around the forefoot - no more crushed pinky toes.
+0.51 in+13 mm instep girthReal space over the top of your foot, where boots usually clamp down.
+0.51 in+13 mm midfoot girthRoom through the waist of the foot, not just the toes.
Same length, every sizeLength and toe box height unchanged - order your usual size. Never size up for width.
Standard vs Wide - the actual numbers
Measured on the same US Women's 8 last (the foot form the boot is built on). Every size gains the same +0.51 in+13 mm of girth and +0.20 in+5 mm of flat width - and every size keeps the standard length.

* These are last measurements, not foot measurements - don't compare them to your own foot directly; use the size finder above instead. Heel girth is the diagonal loop measured from the instep, around the back of the heel. It does open on the Wide last, but deliberately less than everything else: at every size it gains a smaller proportion than the ball and the instep do. On our US 8 sample that is +0.47 in+12 mm at the heel against +0.51 in+13 mm at a forefoot barely two thirds its size, which leaves the heel about 0.28 in7 mm tighter than a proportional scale-up would have made it - so it still holds your foot while the forefoot opens up. Wide comes in every half size from US Women's 4.5 to 14, graded from this base, and we hold measured last data from US 5.5 to 14. Inch figures are converted from the millimetre last sheet and rounded to 0.01 in, so a difference can read 0.01 in off the two figures beside it.

Between Two Sizes?
If your measurement falls between two sizes:
Go UP half a size if:
You plan to wear thick socks β’ Your feet tend to swell β’ You prefer a roomier fit β’ You're between two sizes and unsure
Stay with the smaller size if:
You prefer a snug fit β’ You'll wear thin socks or no-show socks β’ Your measurement is very close to the smaller size
Good to know
Our Microfiber (Vegan) Leather upper has minimal stretch. It won't loosen significantly over time - choose based on your measurement, not hoping it will "break in."
Fit Notes
Two Widths AvailableStandard fits most feet true to size. Wide (same full size range, US 4.5 to 14) adds real girth through the ball, instep and midfoot - for wide feet, bunions, or high insteps.
Upper MaterialMicrofiber (Vegan) Leather: soft matte upper, no chemical smell on arrival, minimal break-in.
Removable InsoleSwap in custom orthotics if needed. Consider going up half a size for thicker orthotics.
Perfect Fit GuaranteeNot the right size? One size exchange per order - free when your order includes Delivery & Fit Protection, otherwise you cover shipping both ways.
Wide Fit - FAQ
How do I know if I need Wide instead of Standard?
Wide is for you if any of these sound familiar: your pinky toe or the outside of your foot goes numb in "normal" boots β’ you've been sizing up to make boots fit your width β’ you have bunions, or your toes feel crushed even when the length is right β’ you have a high instep and boots barely close over the top of your foot β’ you've been told your feet are "too wide" for fashion boots. If none of that applies, stick with Standard - it already runs comfortably roomy.
Should I just size up instead of buying Wide?
No - and this matters. Sizing up gives you width by giving you extra length you don't need. The boot gets longer, your heel starts slipping, and heel slip means blisters and a boot that never feels secure. The Wide version fixes width where width actually lives - around the ball, instep, and midfoot - while keeping the length the same. Order Wide in your true size, not a size up.
I already own Skatheia boots but sized up for room. What Wide size should I get?
Go back to your true size. If your measured foot length puts you in a US 8 but you bought a 9 in Standard to get width, order the Wide in US 8. The Wide 8 has the same length as the Standard 8 - the extra room is all in the width and instep, where you actually needed it.
Will the boot swim on me like other "wide" boots?
Most brands make "wide" by enlarging the whole boot - length included - so you get a longer shoe and a heel with somewhere to travel. Our Wide version keeps the length identical to Standard and puts the extra room around the ball, the arch and the instep instead. You order your true size, so nothing swims.
Is it just a wider toe box?
No - it's wider through the whole front half of the foot. Shoemakers measure width as girth: the circumference around your foot, not just how wide the sole looks. Our Wide version increases girth at all three points that matter - the ball (+0.51 in+13 mm), the instep (+0.51 in+13 mm), and the midfoot (+0.51 in+13 mm). A boot that only splays the toe still pinches everywhere else. This one doesn't.
What width letter is this? D? EE?
We deliberately don't print a letter, because there's no cross-brand standard for widths - one label's D is another label's EE, and a letter says nothing about the instep, where boot trouble usually lives. So we publish the actual measurementsmillimetres instead: Wide adds +0.51 in+13 mm of girth at the ball, arch and instep, and +0.20 in+5 mm of flat width at the widest point, over Standard. If a letter is all you have to go on, measure your foot with the guide above and let the size finder route you.
My feet swell during the day. Will these still fit by evening?
The extra girth through the ball, midfoot, and instep gives your foot room to expand without the boot clamping down. Pro tip: measure your feet at the end of the day, when they're at their largest, and buy for that foot - not your morning foot.
Does the Wide version look bigger or clunky from the outside?
Barely - and most people can't tell at all. The flat width grows just 0.20 in5 mm at the widest point, the length is identical, and the sole, silhouette, and height are unchanged. All of the extra room is in the internal volume. Same boot, same look - it just stops fighting your foot.
