How Bunny Boots Fit
When it comes to Bunny boots, getting the right fit is importnat. After all, you’re not just picking out a pair of shoes for a day at the office—you’re gearing up for some serious cold-weather action!
The folks behind Bunny Boots recently gave their design a makeover to address sizing issues. They noticed the boots were scaling too large as they moved up in size, so they tweaked the heel and instep to ensure a more consistent fit across all sizes.
Now, the updated Bunny Boots come in men’s sizes 4 to 15 and women’s sizes 5.5 to 16.5. They’re also more true to the Brannock Device, which is the gold standard for foot measurement. So, if you’ve got your Brannock size, you’re already one step ahead.

The Golden Rule: Size Down
First things first—Bunny Boots run big. Like, really big. If you’re a US men’s 9, don’t even think about ordering a 9. Go for an 8 instead.
Some folks even recommend sizing down two sizes, but unless you’ve got super narrow feet, sizing down one is usually the sweet spot.
Why do they run big?
Well, these boots are designed to be worn with thick wool socks (we’re talking Arctic-level warmth here). Plus, they need a little extra room to trap air around your toes, which helps prevent frostbite.
So, while they might feel roomy at first, trust me—they’re supposed to.
Overall, you might’ve heard the old saying: “Always go one size larger in a cold weather boot.” But with Bunny Boots, it’s the opposite.
Because they’re already designed to accommodate thick socks and extra insulation, sizing down is the way to go. Trust me, you don’t want your feet swimming in these—they’re bulky enough as it is.
Still unsure? Here’s some advice straight from Bunny Boot wearers:
- “I wear a size 13 shoe, but I ordered a size 13 boot. Big mistake. A size 11 or 12 would’ve been better.”
- “If you’re between sizes, go up and use the Black Insole. It’s a lifesaver.”
- “Don’t forget the thick socks! They make all the difference.”

Foot Width
Bunny boots should feel comfortable, not tight and you don’t want your feet squished in there. But on the flip side, they shouldn’t feel loose either. You want enough space for your feet to breathe, but you also don’t want them sliding around inside the boots.
The key is a snug fit, especially across the arch and midfoot, but with enough room for your toes to wiggle.
Heel Snugness
When you try on Bunny boots, pay attention to how your heel feels. It should be snug but not painfully tight, and it definitely shouldn’t slip out of the boot when you walk. A heel that’s too loose can cause rubbing and blisters, and we all know that’s not something you want on a long cold-weather hike. If your heel is slipping, consider adjusting the lacing, or you might need to go a half size down.

Toe Room
Your toes shouldn’t feel cramped or squeezed. There should be a little wiggle room to let your toes move, which is especially important when you’re layering thick socks for warmth.
You need just enough space to let your toes stretch out without feeling like they’re bumping up against the front of the boot. On the flip side, too much space can leave your feet sliding around, which isn’t ideal for comfort or warmth.
Speaking of socks…

Layering Socks
When trying on bunny boots, keep in mind that you’ll probably be wearing thick socks, or even a combination of socks, to keep your feet cozy in extreme conditions.
So, make sure your boots leave a bit of extra room to accommodate that. If you’re planning to wear just one pair of regular socks, you might find that the boots feel a bit loose, but when layered up, that extra space helps your feet stay warm without compromising circulation.
Here’s where it gets even more interesting…
Men’s vs. Women’s Sizing
Bunny Boots are technically men’s boots, but they’ve got you covered if you’re shopping for women’s sizes. Women’s sizes are 1.5 sizes larger than men’s. For example, if you’re a women’s 8, you’d order a men’s 6.5.
Here’s more info to help you figure it out.
But wait—there’s a catch. Bunny Boots only come in full sizes, so if you’re a half size, you’ll need to get creative…
Bunny Boot Half Sizes
Bunny Boots don’t come in half sizes. Yep, you read that right—only whole sizes. Let me tell you about their genius workaround: the True Fit Insole System.
Instead of offering half sizes, Bunny Boots give you two insoles:
- Red Insole: This is the standard insole, sized to match the boot.
- Black Insole: This little miracle worker reduces the boot’s size by half a size.
Here’s how it works:
- If you’re a 9.5, order a 10 and swap in the Black Insole. Boom—now it fits like a 9.5.
- If you’re an 8.5, order a 9 and use the Black Insole to snug it up.
So, even though Bunny Boots skip the half sizes, they’ve got you covered with this clever system.

Bunny Boot Widths
Bunny Boots are naturally wide to accommodate thick socks and allow for air circulation. They come in Regular (R) and Wide (W) widths, but unless you’ve got extremely wide feet, the Regular width should work just fine.
Let’s take a quick trip down memory lane, because the story of the Bunny Boot is as fascinating as the boot itself.

How to Measure Your Feet
Method 1
If you’re near a shoe store, let a professional measure your feet using a Brannock device which gives you your exact length, width, and arch length.
Plus, the folks at the store can offer personalized advice based on your foot shape and the type of boot you’re buying.
Method 2:
Got a Brannock device at home? Awesome. Here’s how to use it:
- Stand on the device with your heel firmly against the back.
- Slide the width bar to the side of your foot.
- Check the length measurement at the tip of your longest toe (usually the big toe, but not always).
- Note the width measurement (B for narrow, D for medium, E or EE for wide).
- Compare your size to the Bunny boot size chart above.
If you don’t have a Brannock Device, you can download this printable version.

Method 3:
If you don’t have a Brannock,you can still get a pretty accurate measurement at home with just a few simple tools:
- You’ll need a piece of paper, a pen, a ruler, and a wall.
- Trace Your Foot: Place the paper on a hard floor and stand on it with your heel against the wall. Trace the outline of your foot.
- Measure Length: Use the ruler to measure from the wall to the tip of your longest toe.
- Measure Width: Measure the widest part of your foot (usually across the ball).
Use Bunny Boot’s official size chart to match your measurements to the closest size.
Tips to Keep in Mind
- Measure Both Feet: One foot is often slightly larger than the other. Always size to the larger foot.
- Measure at the End of the Day: Your feet swell throughout the day, so measuring in the evening ensures a more accurate fit.
- Wear the Right Socks: Measure while wearing the socks you plan to use with your boots. Thick work socks can add a half size to your measurement.
- Consider Width: If your feet are even slightly wider than average, opt for a wider width. It’s better to have a little extra room than to feel cramped.
The History of the Bunny Boot
From Muk Luks to Military Marvel!
It all starts with the quest for the ultimate cold-weather boot—a journey that’s seen some pretty wild iterations.
The first crack at a winter-ready boot was the Muk Luk: a canvas upper with a cozy wool lining and a leather outsole.
Sounds warm, right? Well, it was—until you stepped into anything wet. Canvas and leather are like sponges when it comes to water, so these boots weren’t exactly ideal for soggy conditions.
Enter the L.L.Bean Boots.
These boots tried to solve the wet feet problem with a rubber bootie on the bottom and a leather upper. It was a step in the right direction—the rubber kept water out from below, but the leather upper? Not so much. Water still seeped in from the top, leaving your toes cold and soggy.
Then came the Mickey Mouse Boot, the Bunny Boot’s predecessor. These boots went full-on rubber, ditching the leather entirely. They were black all over (hence the name) and designed to keep water out completely.
But while they were a huge improvement, they still didn’t quite meet the military’s rigorous standards for extreme cold.
Finally, we arrive at the Bunny Boot—the cold-weather champion. Created during the Korean War by the U.S. Army, these boots were built to withstand temperatures as low as -65°F.
They’re fully waterproof, incredibly insulated, and designed to keep your feet warm and dry in the harshest conditions.
The Bunny Boot is the result of decades of trial and error, and it’s still one of the most reliable cold-weather boots out there.
Alright, let’s wrap this up—because by now, you’re basically a Bunny Boot sizing expert. Here’s the quick recap:
Wrap Up
Remember, Bunny Boots run big so size down if you’re in between sizes. Make sure to take advantage of the True Fit Insole System if you’re a half size. And don’t forget to factor in those thick socks because these bad boys are designed to be worn with heavy wool socks, so factor that into your fit.
