Quick answer

Frank's Boots run large against a Brannock size. On the standard 55 last, start about half a size down. The broader 1977 last sizes a half size smaller again in number, with the same width letter. Use Frank's own length and ball-circumference measurements, not your sneaker size.

Our advice
About half a size down from Brannock on the 55 last; the 1977 sizes lower again. Use Frank's tool.

Frank's Boots run large against a Brannock size, and by how much depends on the last. On the standard 55 last, about half a size down is the usual starting point. On the broader 1977 last, owners report going down further, and the sources we checked disagree on whether that means a full size or about half a size below the 55 equivalent.

That disagreement is worth taking seriously. Frank's is a made-to-order outfit that sizes by foot length and ball circumference, not by your sneaker size, so the best answer comes from its own fit tool and the staff who run it.

Two ways Frank's sizes you

Frank's sells boots two ways. For in-stock boots you measure yourself seated, then match a size and width. For a custom order you submit a fit sheet with a foot tracing and several circumference measurements. Either way, you are not simply picking "your size", and the brand's guidance warns against treating sneaker numbers as a shortcut. The arch support in these boots changes how your foot sits, so a number from a flat, flexible sneaker does not carry over.

The key inputs are foot length and the circumference around the ball of the foot. Width letters are then set from both together: D, E, EE, F and F+ run from narrowest to widest. The same circumference can return different widths at different lengths. In the size chart one article examined, a 10 1/2 inch ball circumference gave an 8F+ at a 10 1/8 inch foot length, but only a 12D on a foot 11 13/16 inches long. A long foot spreads the same circumference across more length, so it counts as narrower.

Fit tip: Do not choose a wider letter just because a standard width felt tight in another brand. Frank's matches width to your ball circumference and your length together, so ask them before you jump up a letter.

The lasts and how they differ

55 (#3)Moderately rounded, medium profile, high arch and heel; the standard HighlanderAbout half a size down
1977 (#4)Broadest, tallest toe box, high arch and heelReports differ: a full size down, or about half a size below the 55 number
HNWSemi-rounded toe, lower arch and heel; Ground Pounder and Monkey BootAsk Frank's; we found no firm figure
5332 (#2)Narrower, lower-profile toe than the 55, traditional high archLimited sizes; ask Frank's
5812 (#1)Narrowest and most pointed, lowest-profile toeLimited sizes; ask Frank's

One thing is clear from Frank's own size calculator, as reported: the 1977 last consistently comes out half a size smaller in number than the standard lasts, with the same width letter. So in principle the same foot that returns a 9E on the 55 would return an 8.5E on the 1977. That is a larger toe box, not a shorter foot.

A real-world data point

One reviewer with a Brannock of US 9 wore an 8.5 in the Hybrid Highlander on the 55 last, which fits the half-size-down pattern. A conversation with the brand reportedly translated an 8.5 in White's Swashbucklers on the 55 last to an 8D in Frank's Highland last. Treat both as anecdotes, but they point the same way: Frank's numbers sit below your Brannock and below many other brands' labels.

Width translations are less reliable. One owner said a 10.5E in Nicks might feel close to a 10.5D in Frank's 55. That is a single report, and the author of the source cautions against converting width automatically. Our Nicks sizing guide and White's sizing guide explain how those makers measure.

Measuring for stock boots

Sit with your knees at about 90 degrees, put your intended socks on, and set each foot flat on a sheet of paper. Mark the heel and the longest toe, and measure between them. Then wrap a flexible tape under the widest part of the forefoot, over the top, around the big-toe joint and just behind the little-toe joint. Keep it snug, not tight. Do both feet and enter each one separately. If the results differ, ask Frank's which size works for both.

If your numbers fall between rows on the chart, re-measure, then ask Frank's whether to round up or down. Our how to measure your feet page has a general version of this routine.

Tracing for a custom fit sheet

The custom sheet is stricter. You trace your feet standing, with weight evenly spread, and take seated circumferences at the ball, instep, heel and leg. The pen matters: a thick or angled pen can skew a tracing by about a quarter inch, according to Frank's staff, so hold a fine tip straight up. Frank's recommends checking measurements several times before you submit them.

Mis-mated pairs, where each foot gets a different size, are offered, but mis-mate orders are final sale. Whether different widths per foot are available is not clear from what we found, so ask before you assume.

What stiff new leather does to your first impression

New Frank's boots feel stiff: thick leather, firm soles and raised arch support. Break-in is long. Owners estimate something like 80 to 100 hours of wear to get fully comfortable, though that varies by pair. Start with sessions of one to two hours at home, wearing the socks you plan to use.

Some limits are worth knowing up front. The leather can stretch a little in width, but not a full width size. A composite toe is bulkier than a steel toe, and neither cap stretches. Toe length problems do not fix themselves with wear. If your toes are hitting the front, that is a sizing problem, not a break-in problem. Heel lift is normal to a point, so adjust the lacing before you decide the boot is too large.

Fit tip: Frank's advises breaking boots in naturally. It does not recommend heat, alcohol-and-water mixes or oils as a shortcut, especially on horsehide and exotic leathers.

Wide, narrow and high-volume feet

If you are broad across the ball, the 1977 is the obvious last to ask about. It has the roomiest toe shape, so a width that felt tight on the 55 may sit differently. If you have narrow feet and a slim ankle, the 5332 and 5812 are the narrow options, but they come in limited sizes.

High arch and high heel are built into every last here, so someone with a flat foot may find the arch support more intrusive than usual. That is one more reason to talk to the maker. For general width questions, see the shoe width chart and wide feet guide.

Thick socks and boot type

Thick wool socks reduce interior room, especially at the instep. If you will wear them, measure with them on. Work boots with a protective cap add another variable, since composite caps take more space than steel and neither flexes. Our how work boots should fit guide covers the toe-cap basics.

Rebuilds and resizing

A rebuild replaces the lower half of the boot and keeps the original upper. That makes it a poor way to fix a bad fit, because the upper stays the same size. Whether you can change the size substantially in a rebuild depends on the boot, so ask before you assume.

Stock or custom: which route suits you

If your feet are close to average and the boot you want is in stock, the stock route is quicker and easier to return or exchange. Custom is for people whose measurements land outside the grid, whose two feet differ a lot, or who want a particular last on a particular leather. It takes longer, and a mistake costs more, so the tracing needs your full attention.

Whichever route you pick, write down your numbers, the date and the socks you wore. If you reorder in a few years, you will want that record, because feet change and memory is a poor measuring tape.

When the numbers say two different sizes

Because the size is built from two measurements, you can end up near a boundary where a small change in either one flips the answer. Do not average the two by instinct. Re-measure, with the foot loaded if the sheet calls for it, and ask Frank's which way to round. The brand's staff see the same situation daily and can usually tell you which side of the line tends to suit your measurements.

Avoid the temptation to "buy a bit big and wear thick socks". In a stiff boot with a high arch, extra length creates heel lift and a toe-box crease in the wrong place. A correctly sized boot feels firm at first and then settles, while an oversized one only feels loose.

Our recommendation

Use Frank's own measurement process, not your sneaker size. As a starting expectation, plan on half a size below your Brannock on the 55 and expect a lower number again on the 1977. Take the width letter from the chart rather than from another brand. Then break the boots in slowly, and contact Frank's if one area keeps rubbing.

Frequently asked questions

Do Frank's Boots run big?

Yes, generally. The sources we checked say they run large against a Brannock size, with about half a size down as the usual start on the standard 55 last. The 1977 last sizes smaller again, so use Frank's own chart or tool.

What is the difference between the 55 and 1977 lasts?

The 55 is moderately rounded with a medium profile. The 1977 is the broadest last with the tallest toe box. Frank's size calculator reportedly returns a number half a size smaller on the 1977, with the same width letter.

What do the width letters mean at Frank's?

Widths run D, E, EE, F and F+, from narrowest to widest. They come from ball circumference and foot length together, so the same circumference can give different widths at different lengths.

Can I use my sneaker size?

Frank's guidance advises against it. The raised arch support changes how the foot sits, so sneaker numbers do not carry over reliably. Measure length and ball circumference instead, and use the brand's chart or fit sheet.

How long is the break-in for Frank's boots?

Owners commonly estimate around 80 to 100 hours, though it varies by pair. Start with one to two hour sessions at home. Break-in softens the leather but will not fix a toe that is too short.
