Astorflex makes some of the most comfortable Italian boots you can slip on, and they’ve been doing it for generations.
But the big question everyone has is about Astorflex sizing. Do you go true to size? Do you size down?
That’s what this guide is here for.
I’ll break down how some of their popular models fit, share tips if you’re between sizes, and include an Astorflex size chart so you can match up your US, UK, and European sizes.
By the end, you’ll know exactly what size to order and how these boots compare to the other heritage brands you might already wear.
Time to jump into the details…
Astorflex Sizing
Key Takeaway on Astorflex Sizing
If you’re coming from US heritage boots, you’ll likely want to go half a size down from your Brannock measurement, which lines up well with Astorflex’s conversion.
For example, a US 9 usually translates to an EU 42, which matches Huckberry’s size chart.
Most of their shoes are only offered in whole sizes, so if you’re in between, it’s usually safer to size down rather than up.
The Patnoflex is easier to nail down because it comes in half sizes, giving you more room to fine-tune the fit.
Fit-wise, Astorflex lasts feel snug in the heel and waist with a relaxed, rounded toe box. That balance makes them comfortable out of the box, though the flat sole and limited arch support can be tiring after long days on your feet.
Bottom line: stick to your US heritage boot size (half size down from Brannock).
Now, with that in mind, let’s dive deeper into the specifics…
Since they’re a European company, their shoes actually come in European sizes. Even if the Huckberry website lists US sizing, you’ll find the European number stamped right on the tongue.
Now, how do they fit?
Well, Astorflex usually runs about a half size down from your Brannock size. And just to be clear, your Brannock size is your real foot measurement on a Brannock device, not your random sneaker size.
Sneakers are all over the place when it comes to fit, so don’t use them as your reference.
So if you’re thinking in boot terms, Astorflex lines up with what you’d expect: about a half size down from true size, and often a full size down from whatever your sneakers say.
But here’s the catch. Astorflex doesn’t do half sizes. Yeah, a bit of a downside. But I’ve read a lot of guys just grab their true size and find them totally fine. So my recommendation is to go down to the nearest whole size if you can.
Also, there are no width options. If you’ve got wide feet, you might need to size up. That said, plenty of wide-footed guys actually love Astorflex because the boots are roomier than most Chelseas. So, if you’re around an E width, you’ll probably be okay without stressing too much.
Fit Checkpoints
So, once you’ve got your pair, how do you know if you nailed your Astorflex sizing?
Here’s what I look for:
- Your heel shouldn’t be sliding up and down with every step.
A tiny bit of movement at first is normal, but if it feels like your foot’s lifting out, that’s too loose.
- Your toes shouldn’t be jammed into the front.
Give yourself a little breathing room, because the leather will soften and open up as you wear them.
- The sides of your feet should feel snug but not squeezed.
Remember, no wide options here, but the roomy design often saves the day for guys with broader feet.
And here’s a little tip: try them on at the end of the day when your feet are slightly swollen. That way you’ll know if they really fit when it matters most.
If all of that checks out, you’re good to go. The break-in won’t be brutal since Astorflex uses softer leather, so the boots should feel comfortable pretty quickly.

Astorflex Brownflex Sizing

The Brownflex runs pretty much the way you’d expect if you’re used to European-made boots. For example, a size EU 40 lines up with a US 9 or a UK 8.
My Brannock size is a US 9, and like with most of my boots, I went down a half size. It worked out the same here.
To give you some context, I wear 8.5 in Red Wing, Thursday, Allen Edmonds, Grant Stone, and Alden. The Brownflex fits me just like those.
So, if you’re a standard D width, going down a half size from your Brannock measurement is the way to go.
Again, Astorflex doesn’t make half sizes or width options. If your feet run wide, you might need to size up a bit, though it’s always smart to double-check with customer service before pulling the trigger.
In my case, the 8.5 feels great whether I wear thin socks, no-shows, or no socks at all. The length feels right, and the width doesn’t give me any hot spots on the balls of my feet.
The midsole and rubber outsole are bendy and flexible right out of the box, so I didn’t deal with heel slip, even though the heel pocket doesn’t have that suede grip you sometimes see.
One detail I really like is the removable footbed. If the fit wasn’t as spot-on as it is, I could swap it out to tweak things or even drop in an orthotic for extra support. It’s a small touch, but it makes the boots way more adaptable.

Astorflex Bitflex Sizing

With the Bitflex, the sizing lined up right where I expected it to. I measure a US 9 on the Brannock device in a standard D width, and in most American boots, I drop down a half size. I went with an 8.5 in the Bitflex, and the fit is spot on.
Again, Astorflex doesn’t offer half sizes or multiple widths. If you’ve got wider feet, you may want to size up, but otherwise the standard fit works well for most people.
For readers outside the US, you’ll see the European size stamped inside the boot. My pair reads a 42, which matches what I usually wear in European sizing.
For comparison, I also wear 8.5 in Thursday Captains, Grant Stone, Parkhurst boots, and White’s (in D width).
On the Oak Street Bootmakers Elston last, I stick to my true size 9, and in Bourdon boots I take a 40. The Bitflex fits right in line with that pattern.
Astorflex Bootflex Sizing
On the Brannock, I measure a US 9 in D width, which translates to a European 42. In most of my heritage boots, I go a half size down, so I usually end up in an 8.5D or a European 40, sometimes a UK 7.5.
With the Bootflex, I went with a size 42, and it turned out to be a solid choice.
The fit feels just right. I’ve got about a thumb’s width of space in front of my toes, and thanks to the rounded toe shape, there are no hot spots or pressure points.
Across the ball of my foot, the fit feels snug in a good way, like that firm handshake analogy people love to use for boots.
Break-in wasn’t much of a struggle. The suede, the lining, and the crepe rubber sole all softened up quickly.
The only spot that gave me some trouble was the stitch right at the corner of the quarters on the outside. That spot needed about two weeks of wear before it fully stretched out. After that, everything settled nicely.
Astorflex Dowelflex Sizing
When I first stepped into the Dowelflex, the comfort felt good right away. The shock absorption works nicely, but I’ll be honest, after a long day, my feet felt a little tired. That’s mostly because of the flat sole and the lack of arch support.
Now, let’s talk sizing. The Astorflex site matches a US 9 to a European 42. On the Brannock, I measure a US 9, but like most heritage boots, I usually wear a half size down into an 8.5.
My European sizing tends to bounce between 42 and 42.5, depending on the brand.
If you’re going by Huckberry’s conversion chart, the safest move is to stick with the size you normally wear in American heritage boots, which is basically, a half size down from your Brannock measurement. That worked well for me.
Fit-wise, the Dowelflex feels snug in all the right places: the heel, the waist, and across the ball of my foot. It doesn’t pinch, and the rounded toe shape gives me just enough room in the toe box so nothing feels cramped.
So, if you’re like me and usually size down half a step in boots, you’ll probably want to do the same here.
How to Measure Your Feet for Astorflex
It might sound obvious, but most people skip measuring their feet and end up with shoes that pinch, slip, or feel just a little “off.”
Here’s how to do it the right way so you can skip the guessing game.
Step 1: Measure at the Right Time
Feet aren’t the same size all day. They swell slightly as the day goes on, so the best time to measure is in the late afternoon or evening when they’re at their largest. That way, your shoes won’t feel tight after a long day of walking.
Step 2: Grab the Right Tools
You don’t need anything fancy: just a sheet of paper, a pen, a ruler or measuring tape, and some socks similar to the ones you’ll wear with your Astorflex shoes.
If you have access to a Brannock device (the metal tool they use in shoe stores), even better, but paper and pen work just fine.
Step 3: Trace Your Feet
- Place the paper flat on the floor against a wall.
- Stand on it with your heel touching the wall and your weight evenly balanced on both feet.
- Trace around your foot with the pen held straight up and down (not angled).
- Do this for both feet because they’re often slightly different sizes.
Step 4: Get Your Measurements
- Measure the length from the back of your heel to the tip of your longest toe (sometimes it’s not the big toe!).
- Measure the widest part of your foot.
- Write both numbers down in centimeters or inches.
- If one foot is larger, always go with that measurement.
Step 5: Compare With Astorflex’s Size Chart
Once you have your measurements, check them against the Astorflex size charts below. Their shoes usually run true to size, but some styles, like the Greenflex desert boot, can feel a bit roomy.
If you’re between sizes, sizing down often gives a snugger, glove-like fit, while sizing up adds more wiggle room.
Step 6: Think About Width
Most Astorflex shoes come in a standard width, but if you have wider feet, pay close attention to the width measurement you took.
If your width is higher than average, you might want to size up half a size for extra comfort, especially in more structured styles.
Step 7: Double-Check With Socks
The thickness of your socks changes the fit. If you plan on wearing thicker socks with your boots in winter, measure with those on. If it’s mostly summer wear, go with thinner socks.
Bonus Tip: Try the “Finger Test”
Once you get your shoes, there’s a quick way to check if the size is right. Slip them on and see if you can slide one finger behind your heel. If you can barely squeeze it in, you’re good. If there’s too much room, the shoes might be too big.

Six Generations of Shoemaking

Family Beginnings in Italy
Astorflex has roots that go back more than a century. The Travenzoli family started making shoes in the late 1800s in the small northern Italian town of Castel d’Ario.
Back then, the town was full of family-run workshops, each turning out handmade boots and shoes. It’s a bit like how Bandung in Indonesia is known today for clusters of small shoemakers working side by side.
From Workshop to Factory
View this post on Instagram
After World War I, the Travenzolis shifted from being a small workshop to running a proper factory.
Even with that change, they kept their focus on traditional stitch-down construction, which is still part of their identity.
Over the decades, Astorflex became known across Europe for reliable, well-made footwear that kept ties to its artisanal roots.
Embracing Sustainability
Fast forward to the late 20th century, and the family, now into its sixth generation of ownership, started steering the company toward a more eco-conscious approach.
Instead of chrome-tanned leathers that can cause harmful runoff, they use vegetable-tanned calfskin. Soles are made from natural rubber, dyes are water-based, and glues are free of harsh solvents.
It’s a modern way to honor their traditional craft because, in many ways, old-world shoemaking was always closer to sustainable by nature.
Astorflex Today
Today, Astorflex is still family-run and continues to balance tradition with modern values. For almost a decade, they’ve partnered with Huckberry to bring their boots to a wider audience in the U.S.
Beyond the lace-up Bootflex, the lineup now includes loafers, Chelseas, and chukkas, most of them carrying that familiar “Flex” name.
So, you’ve got a heritage brand with six generations of know-how, a reputation for comfort, and a real effort to keep things eco-friendly. Not bad for a small-town workshop that started over a hundred years ago.
FAQ: Astorflex Sizing & Fit
Do Astorflex boots run true to size?
Not exactly. Most Astorflex boots fit about a half size down from your Brannock size (your actual foot measurement). So if you measure a US 9 on the Brannock, you’ll likely do best in a US 8.5 in Astorflex.
Why do Astorflex boots use European sizing?
Astorflex is an Italian brand, so the sizing is based on the European scale. Even if the website shows US sizes, you’ll see the European size stamped inside the boot. For example, a US 9 usually equals a European 42.
If I wear sneakers, how should I size?
Sneaker sizing can be tricky since brands vary so much. As a general rule, expect to go down about one full size from your sneaker size to get the right Astorflex boot fit.
Do Astorflex come in half sizes?
Most Astorflex models do not come in half sizes, which can be frustrating. The exception is some shoes like the Patnoflex loafer, which does offer half sizes. If you’re between sizes, go to the nearest whole size down.
Are Astorflex boots good for wide feet?
Even though they don’t make wide widths, Astorflex boots are known to have a roomier fit than most Chelseas and chukkas. Many guys with E-width feet say they fit well. Still, if you’re on the wider side, consider sizing up to the next whole size.
How does Astorflex compare to other boot brands?
Astorflex sizing is very similar to Thursday Boots, Grant Stone, and White’s. If you know your size in those, you’ll probably wear the same in Astorflex.
Is there a break-in period?
Astorflex boots are softer out of the box than most heritage boots, thanks to the suede, leather lining, and crepe soles.
You might notice a small break-in period, especially at the stitch points, but it’s nothing compared to heavier-duty boots.
Final Thoughts
At the end of the day, Astorflex sizing is actually pretty easy to nail once you know where you stand.
If you stick to the size you usually wear in other heritage boots, you’re going to be fine. The brand’s use of soft suede, crepe soles, and relaxed lasts means the break-in is short and the fit feels forgiving compared to stiffer work boots.
The main thing to remember is that Astorflex runs true to size for most people, and if you’re between sizes, going down half a size usually works better than going up. And since models like the Patnoflex even come in half sizes, it’s easier to dial in the fit.
Make sure you use the Astorflex size chart as a reference, line it up with your go-to boot size, and you’re good to go.
