Every pair is printed after you order it, so no spare box waits in the next size up. Two numbers settle it: your longer foot, and whether it wants room around the middle.
Find your size
Standard is the fit every Edition is built on. Twenty sizes, from a 4.5 up to a 14.
Your size is in the chart below.
The slider on this page is not running, so it cannot read your measurement. The full twenty-size run further down this page has every answer it would have given you.
Got it wrong? Your first size change stays open for thirty days, two sizes either way.
How to measure at home
Print at 100 percent. Turn off Fit to Page, Shrink to Fit and Scale to Paper. A few millimetres lost is a whole size.
Then measure the printed 5 cm bar. Hold a ruler against it. If it does not read 5 cm, the paper is lying to you. Print it again.
A long foot uses the other ruler. The straight one serves a foot up to 27.4 cm on US Letter and up to 29.1 cm on A4, a US 11 and a US 13. Past that, use the diagonal: heel on the terracotta dot, foot along the line. It carries all the way to 29.9 cm.
No printer? A tape and blank paper do it too.
- Hard floor, socks onCarpet gives under your heel and hands back a short number. Wear the socks you mean to wear in the boots.
- Stand, full weight, pen uprightA loaded foot reaches further than a lifted one.
- Read the length, then swap feetOn many women the second toe is longest. The bigger foot decides.
Do it late in the day. The foot to keep comfortable is the one at the dinner table at nine.

Foot up to is the longest foot each size takes with 5/16 in still clear ahead of the toes. Insole is the inside length of the boot, which sits about 3/8 in past the foot it was drawn for. That margin is what your toes travel into at every step. On a phone, drag the table sideways.
When you land between two rows
- Take the half size up for thick socks, for feet that swell by evening, or for an orthotic going in.
- Hold the smaller row for thin socks, a close fit, or a number that only just cleared.
A half size will never buy width. Short of room around the foot, not past the toes? That is Wide, not the next row down.
Standard or Wide?
Three signs the Wide fit is yours.
- Boots that fit for length still squeeze across the front.
- You buy a size up purely to get across, then swim in the length.
- Your foot stands high and no lace closes without hurting.
Every millimetre we hold, and every question, sits on one page.
Fit notes
Two fits, one length
Both fits run all twenty sizes, 4.5 to 14. Wide changes girth, never length.
The insole lifts straight out
Black woven top, pale foam under it. An orthotic goes in its place and eats room, so between two sizes take the larger.
One size change per order
Thirty days, two sizes either way. Postage is ours both ways with Return & Exchange Protection, yours without; start at cs@sunayla.com or read returns and refunds.
No size can run out
Nothing is cut until your order exists, so no size is ever gone. What that buys is choice rather than speed, and the making time sits on shipping and delivery.
Still not certain
Email cs@sunayla.com with both measurements, the socks you mean to wear, and the Edition you are looking at. Otherwise you have your number. Go and pick your pair.
