If you’re here, you’re probably wondering: How should my hiking boots fit?
When it comes to hiking boots, there’s no shortage of fantastic brands out there—Keen, Salomon, Merrell, Lowa, Red Wing and so many more.
These trusted names make some of the best boots on the market, but here’s the thing: even the highest-quality boots won’t do you any favors if they don’t fit right.
And let me tell you, I’ve seen way too many hikers struggle with blisters, pain, and discomfort simply because they didn’t nail the fit or break-in process.
Let’s get straight to the heart of the matter: how your foot should feel inside a hiking boot…

How Should Hiking Boots Fit
A lot of folks think their boots fit too tight when, really, the issue often comes down to improper sizing. Did you know your arch length (that’s the measurement from your heel to the ball of your foot) can be longer than your heel-to-toe size? If your boots aren’t aligned with that, you’re setting yourself up for a world of discomfort.
Oh, and let’s not forget: not all boots feel the same. A sturdy, chunky boot like the Alt-Berg Tethera is going to feel worlds apart from something lighter and more flexible, like the Salomon Mid Light.
Even with softer uppers that flex and mold to your foot, the fit still needs to be spot-on.
A good fit isn’t just about length—it’s about where your heel sits, where your toes land, and how the ball of your foot aligns with the boot’s structure.
A good fit should feel snug but not constricting, with the understanding that the boots will mold to your feet as they break in.
Your boot should feel snug around the heel and midfoot, with a little wiggle room for your toes. If it feels too tight or too loose right off the bat, that’s your first red flag.
Once you lace up the boot, it should feel secure but not uncomfortable. And hey, if the cuff of the boot feels like it’s squeezing your calf, it might be time to consider a lower-cut style.
If you feel any pressure points—especially around the sides or top of your toes—you might need a larger or wider size.
On the flip side, if you can pinch a bunch of material above your toes, the boots are probably too big or too wide for you.
And if you’ve got narrow heels? Look for boots with extra cushioning or try the heel lock lacing technique to keep your heel from slipping.

Test It on a Decline
Your living room floor won’t cut it for this next step. Take those boots outside and find a steep hill. Walk downhill and pay close attention to how your feet move inside the boots.
- Walk Uphill: Take small, exaggerated steps to check if your heel stays secure. If you’re sliding forward, they’re too big. Tighten the laces or consider a different pair.
- Walk Downhill: Again, take exaggerated steps. If your toes are slamming into the front, the boots are too small
What you want is a boot that keeps your heel and midfoot locked in place while giving your toes just enough room to move naturally.
The End-of-Day Test
Here’s a trick I swear by: after a long day of wearing your old boots, slip into your new ones. Why? Because your feet swell throughout the day, and this will give you a much more accurate sense of how the boots will feel during a real hike. If they still feel great when your feet are at their puffiest, you’ve got a winner.
The Golden Rule
Any movement in the heel of a laced hiking boot is a big no-no. Your heel should stay put, no matter what. Take your time to find the right pair.
Now that you know how your hiking boots should fit, let’s walk through the step-by-step fitting process to make sure you get it right—because even the smallest misstep here can lead to big problems on the trail.

How to Check the Fit of Your Hiking Boots
So, you’ve got your shiny new hiking boots, and you’re itching to hit the trails. But before you do, let’s make sure they’re going to treat your feet right.
Whether you bought them online or in-store, this step-by-step fitting process will help you avoid any nasty surprises out on the trail. Trust me, a little patience now will save you a lot of pain later.
1. Check Heel and Toe Space
Start by sticking two fingers behind your heel while wearing the boots. You should be able to do this with just a little wiggle room—about ½ inch of space. This ensures that once you snug up the laces and pull your heel back, you’ll have enough room in the front for your toes.
Why does this matter? When you’re hiking, your feet will swell, and if you bump into rocks or walk downhill, you don’t want your toes slamming into the front of the boot. That little bit of space is your buffer against discomfort and black toenails.

2. Test the Insole Fit
Here’s a foolproof way to check if your boots have the right amount of toe room:
- Take the removable insole out of the boot and place it on the floor.
- Stand on the insole with your heel pushed all the way back, just like it would sit in the boot.
- Look at the space between your longest toe and the end of the insole. There should be about a finger’s width of space between your longest toe and the end of the insole—somewhere between ½ inch to ¾ inch.
- Width: Your foot should sit comfortably within the edges of the insole. If your feet spill over the sides too much, the boots are too narrow. If there’s a ton of extra space, they’re too wide.
If your feet spill over the insole just a little bit, that’s pretty normal. Boots sort of cut round coming up from the insole, so there’s usually a bit more width than the insole will show.
But here’s the thing: the stock insoles that come with most boots? They’re… fine. But “fine” doesn’t cut it when you’re tackling rugged trails.
Those factory insoles are designed to be one-size-fits-all. They’re meant to feel decent in the store, but they’re not tailored to your feet. Sure, some brands hype up their “fancy foam” or “advanced support systems,” but at the end of the day, they’re still generic.
If you want real comfort and support, it’s worth swapping out the stock insoles for an aftermarket pair. Look for options with rigid arch support and a shape that matches your foot.

3. Lace Them Up Properly
Once your foot is in the boot, tap your heel on the ground to seat it properly. Then, start lacing from the bottom and work your way up, snugging the laces as you go. You want the boots to feel secure but not uncomfortably tight.
Those two eyelets opposite the heel are absolute game-changers because they’re the key to locking your heel in place. This is especially crucial with stiff boots, like mountaineering boots or winter boots, where a secure fit can make or break your stability.
If you don’t tighten these eyelets properly, a stiff boot can lift your heel, leading to slippage and discomfort. But when you snug them up just right, they not only keep your heel firmly planted but also help prevent ankle rolling—a lifesaver on uneven terrain.
So, don’t overlook those eyelets. They might seem small, but they’re mighty when it comes to keeping you steady and secure.
Pro tip: Make sure the tongue is centered and straight. A crooked tongue can cause pressure points and uneven fit.

1. Wear Them Around the House
I get it—new boots are exciting, and you probably want to take them straight to the mountains. But resist the urge! Instead, wear them around the house for at least 30 minutes over three evenings. This gives you time to spot any issues before you’re miles from civilization.
Here’s a pro tip: distract yourself while wearing them. Do some chores—vacuum, fold laundry, or even dance around the kitchen—anything to distract yourself from focusing on your feet. If you forget you’re wearing them after a couple of hours, that’s a great sign. If you’re focused on something else and still notice discomfort or pressure points, that’s your cue that something’s not right.
5. Wear Them Around the House
Do some chores, walk up and down stairs, or even vacuum—anything to distract yourself from focusing on your feet. If you forget you’re wearing them after a couple of hours, that’s a great sign.
2. Walk Around in Them
Spend some time walking on flat ground to get an overall feel for the fit. Your heel should stay put, the ball of your foot should align with the widest part of the boot, and your toes should have room to wiggle.
2. Test Them on a Staircase or Edge
Next, head over to a staircase or a small ledge in your home. Place your toes on the edge and lift your heels up and down a few times. What you’re looking for here is heel movement.
A tiny bit of slip (under a centimeter) is normal and won’t cause issues on the trail. But if your heel is lifting dramatically, the boots are too big. That kind of movement will lead to blisters and frustration, so it’s worth sizing down or trying a different model.

3. Try Them On at Different Times of the Day
Your feet aren’t the same size all day long—they swell as you move, especially if you’ve been on your feet for hours. That’s why it’s important to test your boots at different times.
Try them on in the morning when your feet are at their smallest, and then again in the evening after a long day. Pay special attention to the width—this is where swelling tends to show up the most. If they feel snug but comfortable at the end of the day, you’re golden.
6. Break Them In Gradually
Hiking boots aren’t meant to feel like slippers right out of the box. Wear them for short walks, errands, or light hikes to break them in incrementally. Aim to put 10–20 miles on them before tackling a long hike or multi-day backpacking trip. Trust me, your feet will thank you.
5. Don’t Rush the Process
Finding the perfect fit isn’t a race. Take your time, follow these steps, and don’t settle for “good enough.” Your hiking boots are your foundation on the trail—if they’re not right, nothing else will be.

How to Measure Your Feet: The Brannock Device and At-Home Tips
If you haven’t had your feet measured for a long time, they’re usually bigger than you think. Our feet expand and spread over time, so please get this right. It’s very important.
And certainly, the number one mistake you might make is just guessing what your foot size is based on the last pair of shoes you wore.
But while online shopping is convenient and often tempting, there’s no substitute for getting fitted in person by a professional. Here’s why:
First, a trained associate can measure your feet using a Brannock Device, which provides precise measurements for length, width, and arch size.
Second, trying on boots in-store lets you test multiple brands and styles to see how they feel on your feet. You can walk around, test them on inclines, and get a real sense of how they’ll perform. Plus, you’ll have access to expert advice. A good fitter can recommend boots based on your foot shape, hiking style, and any specific needs, like narrow heels, wide toes, or high arches.
Finally, getting fitted in person helps you avoid the hassle of returns and exchanges. It’s a time-saver and ensures you leave with boots that feel right from the start. So, if you can, visit a store for your first fitting. It’s the best way to set yourself up for success—and for miles of comfortable hiking.

The Brannock Device is the universal gold standard for measuring your feet. most boot brands will tell you how their sizing compares to the Brannock measurement. But even if they don’t, knowing your Brannock size gives you a solid starting point.
If you have access to a Brannock Device, here’s how to use it like a pro:
First, make sure you’re wearing the socks that you would be with that boot. Don’t measure yourself barefoot and then put a really thick sock on because it’d make a huge difference.
- Stand Up Straight: Place your foot on the device with your heel snug against the back. Your weight should be evenly distributed—this ensures your foot is in its natural, expanded state.
- Measure Length: Slide the slider forward until it touches the tip of your longest toe (it’s not always the big toe!). Read the measurement at the edge of the slider.
- Measure Width: Look at the width bar on the side of the device. It should align with the widest part of your foot, usually near the ball. The letters (like B, D, or E) indicate the width.
- Check Arch Length: Some Brannock Devices have a sliding pointer for arch length. This measures from your heel to the ball of your foot, which is crucial for ensuring the boot flexes in the right place.
Write down your measurements and use them as a guide when shopping for boots. Remember, sizes can vary between brands, so always prioritize fit over the number on the box.
Measuring Your Feet at Home
No Brannock Device? No problem. Here’s how to measure your feet accurately at home:
- Gather Your 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 lightly touching a wall. Trace around your foot, keeping the pen perpendicular to the paper for accuracy.
- Measure Length: Use the ruler to measure from the wall (or the edge of the paper) to the tip of your longest toe. This is your foot length.
- Measure Width: Find the widest part of your foot and wrap the tape measure around the widest part of your foot.
Pro Tips:
Measure Both Feet: One foot is often slightly larger than the other. Always size for the bigger foot.
Do It at the End of the Day: Your feet swell throughout the day, so measuring in the evening ensures a more accurate fit.
Use a Sizing Chart: Once you have your measurements, compare them to the brand’s sizing chart. Don’t assume your size is the same across all brands—it rarely is. Hopefully, this will help you convert your size into US sizes because some of the hiking boots come in EU sizes.

The Role of Socks in Finding the Perfect Fit
Let’s talk about something that often gets overlooked but can make or break your hiking experience: socks. Yes, socks! They’re not just an afterthought—they’re a critical part of the fitting process. Here’s why:
When you’re testing out new hiking boots, always wear the socks you plan to hike in. Sounds obvious, right? But you’d be surprised how many people try on bulky boots with thin dress socks or, worse, no socks at all.
The thickness (or thinness) of your socks can completely throw off the fit. Too thick, and your boots might feel tight and restrictive. Too thin, and your feet could slide around.
A good pair will wick moisture away from your feet and also provide cushioning in key areas, like the heel and ball of your foot, which can make a huge difference on long hikes.
Think of your socks and boots as a team. The right socks will enhance the fit of your boots, while the wrong ones can ruin it.
Pro Tip: If you’re unsure which socks are going to fit you better, bring a few different pairs when trying on boots. Test them out to see which combination feels best.
Common Fitting Issues (and How to Fix Them)
Even the best hiking boots can have a few quirks when it comes to fit. But don’t worry—most issues are fixable with a little know-how. Let’s dive into some common problems and their solutions.
1. Heel Lift
A little bit of heel lift isn’t a dealbreaker, but if it’s excessive or uncomfortable, it’s time to take action.
- Check Your Lacing: Start by ensuring your boots are laced correctly. Use techniques like the heel lock to secure your foot.
- Try a Heel Lift: If lacing doesn’t solve the problem, a heel lift can work wonders. This simple insert sits under the insole at the back of the boot, raising your heel into a narrower part of the boot to eliminate slippage.
2. Boots Are Too Wide
If your boots feel roomy, don’t toss them just yet. Try these fixes:
- Wear Thicker Socks: Opt for heavyweight Merino Wool socks (like Camel City Mill) for extra padding without sacrificing breathability. Avoid cotton or polyester—they trap moisture and can leave your feet feeling swampy.
- Add an Insole: Swap out the stock insole for a thicker aftermarket one. Orthopedic insoles can take up a full half-size of space, while foam or leather inserts offer a more subtle adjustment.
- Use Heel Cushions: These adhesive pads stick to the back of your boot and are perfect for reducing heel slip without altering the overall fit.
- Try Shoe Fillers: If you have too much room in the toe box, foam fillers can take up space at the front. Just be cautious—they can throw off the arch alignment, making them less ideal for long hikes.
- Visit a Cobbler: For boots that are a size and a half too big, professional recrafting might be your best bet. A cobbler can rebuild the boot to fit your foot better, though this option isn’t cheap.
If you’ve tried all these hacks and your boots still feel too big, it might be time to invest in a better-fitting pair.
3. Boots Are Too Narrow
Narrow boots can be tricky, but here are a few ways to create more room:
- Loosen the Laces: Start by giving your feet some breathing room. Loosening the laces, especially around the forefoot, can make a big difference.
- Switch to Thinner Socks: If you’re wearing bulky socks, try a thinner pair that still offers comfort and padding. Look for options that aren’t as bulky around the forefoot.
- Stretch them.
All in all, your hiking boots should feel like an extension of your feet: snug but not tight, supportive but not restrictive, and ready to take on whatever the trail throws your way.
Remember, the right fit starts with knowing your foot measurements, understanding how your boots should feel, and taking the time to test and break them in properly. Don’t settle for “good enough”—your feet deserve better. And if you’re ever in doubt, don’t hesitate to seek help from a professional or try on multiple pairs until you find the one.
