Are Your Boots Too Big? Make Them Fit Better in Just 5 Steps (2024)

Boot fit can be surprisingly complex. Sometimes a pair feels perfect when you try them on at the store, then they magically grow a size when you’re out and about.

Maybe you have two different sized feet, so one foot sits comfortably in its boot while the other is sliding all over the place.This is why sizing up is often a better option compared to wearing overly tight boots.

The opportunity cost of exchanging sizes isn’t always worth it.. You might get an ill-fitting boot all over again and it’s back to square one.

I’ve broken this problem down on our YouTube channel as well if you prefer watching a video:

How to Tell If Your Boots Are Too Big

If your foot slips around inside your fully fastened boot as you walk, the boot is too big.

A bit of heel slippage is normal during break-in, as long as it isn’t over half an inch. Significant heel slippage can cause chafing and blisters.

For slip-ons, you’ll have to exert some pressure to thrust your heel into the boot. If it slips in too easily, your foot won’t be secure enough.

You must have an inch of room in the toe box. This section of the boot isn’t actually the best place to determine if it’s too big. Most people run around in shoes that are too small for them.

Pressing down on the toe-box to ensure fit is an all too common practice, and it’s easy to misread the extra space as a sign to size down.

On that note, make sure to try on new boots at the end of the day because your feet will be more swollen then than in the morning. Wear the style of socks you’ll pair with the boots to simulate its truest fit.

If you live your life in boots that are too big for you, your foot’s flexpoints will be off and it won’t bend at the break points it’s naturally designed to. This is a sure-fire way to get inflammation and plantar fasciitis.

Probably the easiest way to fill in the extra space you have in your boots is to get a thick pair of wool socks. My favorite are the Camel City Mill Heavyweight wool socks. They have a ton of padding throughout the entire footbed and the calf so they do double-duty in adding volume and protecting your feet from blisters.

What You’ll Need to Make Your Big Boots Fit Better

• Heavyweight socks
• Insoles
• Heel shields
• Boot filler
• Shoe repair adhesive, like Shoe Goo (optional)

5 Steps to Make Big Boots Fit Better

Step 1: Walk Around and Take Note

Walk around in your boots and take note of any specific pain points. Where is the most excess room? What parts of your foot are most uncomfortable? Your right foot may have different issues than your left foot.

Knowing the problem areas is going to help you find the right product to fill up the extra space.

Step 2: Wear Thick Socks

You may have already tried this, but if you haven’t, it’s the first step to getting your big boots fitting a little more snug.

Wear thicker wool socks. A thick pair of socks can increase your foot volume by up to a half-size, which is pretty impressive. I like the Camel City Mill Heavyweight when my boots are a little too big.

Step 3: Add an Insole

Choose an insole based on your examination. For example, if there’s heel slippage, go for a mid to high volume insole to stabilize the heel. If the sides are particularly roomy, go for a wider insole.

Tread Labs is my favorite brand for insoles.

Step 4: Add a Heel Cushion

Place the insole in the boot and test for comfort and fit by walking around in them, fully fastened. You might have to trim the insole to get your desired fit.

If you’re lucky, this may be the last step. If it feels comfortable but slips out of place, use shoe tape to secure the insole. If there’s still heel slippage and rubbing, apply the heel shields.

Step 5: Add Boot Filler

Wear them around for a day or two before permanently securing anything to see if you need to make any further adjustments.

If there’s still too much room in your boot, you may need to bring in the big stuff—I’m talking about shoe filler. It’s basically a foam pad that fills in the extra space in the toe of your boot.

Best Insoles for Boots That Are Too Big

Tread Labs Insoles give you a level of customization rarely found with over-the-counter insoles.

They’re made of two parts: A hard arch support mold that comes in low, medium, high, and extra high, and an interchangeable foam top that you can customize based on several qualities including firmness, arch support thickness, size (important for our purposes today), and more.

They offer many models to address specific symptoms. For example, the Pace model is recommended for those seeking pain relief, and the flexible Ramble model is for comfort. You can simultaneously improve the fit of your big boots, while addressing the specific challenges unique to your feet.

Finally, Tread Labs offers a “million mile guarantee” which means the medical-grade arch support mold will last forever.

My Overall Thoughts on Tread Labs Insoles

What Happens if Your Boots are Too Big?

1. Blisters

If your boots are too big, you’re going to get a blister. Most often, big boots give you a blister on your heel, but you can also experience blisters around the ball of your foot and even the bottom of your foot.

If your boots are broken in but you’re still getting blisters, that’s a sign that you might need to try some hacks to get them to fit better.

2. Foot Fatigue

When your boots are too big, you’re putting a lot of extra strain on the smaller muscles of your foot. Your ankles might start to feel tired (test by lifting your foot up and down—if it feels more difficult than usual, then your muscles are exhausted).

But your ankle isn’t the only place you’ll feel it: your toes, achilles, and even minor muscles through your arch can start to get tired, which isn’t a problem in and of itself, but it can lead to…

3. Ankle Injuries

When your feet start to get tired, you’re more prone to injury. And boots that fit too big are especially hazardous for your ankles.

Whether it’s rolling your ankle by taking an awkward step, or your muscles are just worn out from your feet sliding around in your boots, a secure, well-fitting boot is an easy way to prevent injury.

This is especially true if you’re wearing a boot with a heel, like a cowboy boot that’s too big. The heel can easily roll off to one side or another, and that’s where you either roll your ankle or go down.

4. Hammer Toes

Have you ever worn a pair of flip-flops and noticed at the end of the day that your toes are in pain? When you “scrunch” your toes to keep your foot close to the insole of your boots, it can cause pain over time.

That’s called hammer toes. And it’s annoying one day. But if you keep doing it over and over again, it can actually cause permanent injury, so it’s important to fix your fit issues if your noticing toe soreness day after day.

5. Bunions

Bunions—they’re not just for grandma. If your boots are loose, they can cause bunions on you, too.

A lot of times, bunions are caused if you have flat feet, but wearing boots with too much width can essentially mimic the effect of flat feet and cause your big toe to flare out. With bunions, it only gets more and more uncomfortable, so you want to do everything you can to avoid them in the first place.

Make it Work

Boots that are slightly too big for you aren’t the end of the world. There are certainly more ways around them than boots that are much too small, at least with the right insoles and some gumption.

Of course, if you’re a size 9, no amount of heel shields and arch support will make a size 15 boot work for you.

If you’re moving up from a half size or a friend just slightly missed the mark with a gift, properly applying insoles can save you a lot of discomfort. This strategy is also helpful when you find a certain brand sizes its boots just a bit differently than you’re used to.
