How Sandals Should Fit: A Guide to Finding the Perfect Pair
The sun is shining, the days are getting warmer, and you’re ready to spend time doing all your favorite things—exploring the city, driving around town with the windows down and the music up, or getting together with friends. All that’s left to do? Put the final touches on your outfit and head out the door. But as soon as you slide into your fresh new sandals, you realize something’s not right.
It could be the strap’s a little too tight around your ankle, or the sole’s too loose and slides all over the place. Or maybe your toes are being squished in a way that just feels... off. Whatever it is, it’s a total mood killer.
These types of summer sandal struggles are all too common. But we’ve got good news—you don’t have to deal with them! It just takes a bit of research, starting with one simple question: “How should sandals fit on your feet?”
Here’s the even better news: We’ve packed everything you need to know into one convenient blog post. (Because we’re always happy to help out where we can.)
Sandal Sizing: How Should Sandals Fit?
There are a couple of key mistakes people tend to make in terms of how sandals should fit. The first is picking a pair just by the size listed on the box. This rarely works because sizes can vary a lot from one brand to another, and even between different styles within the same brand. What fits perfectly in one pair might feel way too tight or loose in another, even if they’re the same size.
It’s always a good idea to try them on, if you can. You’ll get a better feel for how they fit your foot, how the straps sit, and whether they give you that all-day comfort you’re looking for.
The second mistake? Not walking in the sandals before buying. Sure, they might seem perfect when you’re just standing, but it's those few steps that can tell you if the straps dig in or if the support isn’t quite what you need. A quick walkaround is always worth it!
And lastly, different styles are designed with specific foot shapes and needs in mind. Take slide sandals, for example—they’re meant to be easy to slide on and off, so they fit super loose. This isn’t ideal for those needing a more secure fit. On top of that, they usually fall short in providing arch support, which can be a dealbreaker for anyone wanting a more cushioned or stable sole.
In short, keep these three things in mind for a proper sandal fit:
- Focus on fit, not the listed shoe size.
- Take a quick stroll in them before you commit.
- Each sandal style is designed to fit a little differently.
Key Elements of Well-Fitted Sandals
When you're shopping for sandals, the best time to make sure they fit right is right there in the store—before you make the purchase. No one wants to spend their hard-earned money on something that isn’t quite right. So, how can you be sure you’re getting a pair that feels practically custom (without the price tag)?
Here are a few key tips you can follow:
- Toes: Everyone’s toes are shaped differently—some have a more square shape, while others taper (they gradually get shorter from the big toe to the little toe)—yet we rarely consider this when shopping for shoes. Think about how you want your sandals to fit in the toe. How should sandals fit to make you most comfortable? If you have a square foot shape, you’ll likely feel best in a wider style sandal, like footbeds or fisherman sandals. If you have a tapered shape, you can try more narrow styles like pointed toes or oblique-shaped options.
- Heel: It’s a question that isn’t addressed enough: How should sandals fit in the heel? The back of a shoe plays a major role in how it feels and supports the rest of the body. If you need more stability, block heels are a great choice. If you want height without discomfort, try platforms. And for a sleek, dramatic shape? Stilettos are the ultimate go-to.
- Space: It’s not uncommon for people to buy sandals too small for them, either for a sleeker look or because they weren’t available in their usual size. This causes chafing, discomfort, and even blisters. A good rule of thumb? You should have half an inch of space between the top of your big toe and the front edge of your sandal.
- Comfort: Sandals should always make your foot feel supported, snug and cushioned. Look for options that absorb the impact of your steps as you walk, and always make sure you don’t feel any pinching, rubbing, or pressure points.
- Arch Support: Your sandals should have adequate arch support, so you aren’t leaning too heavily on the balls or heels of your feet. You should also feel stable with each step, not wobbly or off-balance.
- Strap Fit: Sandal straps should be snug, not restricting, and should keep your foot well-positioned. If you notice slipping, red marks, or skin irritation, that’s a sign to find an alternative.
Now that you know how sandals should fit in the back, in the toes, and in terms of general comfort, let’s take things a step further by exploring how to measure your foot and find a pair of sandals that fit like a dream.
How to Measure Your Foot for the Perfect Sandal Fit
Measuring your foot is the best way to get that “tailored to perfection” feel every time you buy a new pair of sandals—which means fewer returns, fewer regrets, and a much higher chance of loving your shoes from the very first wear.
Here’s how it’s done in just a few simple steps:
- Stand on a piece of paper and trace around your foot.
- Using a ruler, measure from the back of your heel to your longest toe.
- Measure across the widest part of your foot.
- Repeat the process for your other foot. (They’re often slightly different sizes!)
- Use the bigger measurement when checking size charts.
Warning Signs Your Sandals Don’t Fit Right
From the elements of a well-fitting shoe to how to measure your foot, “How should sandals fit?” is a more complex question to answer than you probably expected. But trust us, learning all the best tips and tricks is well worth the time and effort. Once you know what to look for—and what not to look for—you’ll be picking perfect pairs like a pro!
Speaking of what not to look for, let’s talk about the biggest red flags when it comes to size and fit.
Signs Your Sandals Are Too Small
Whether you’re eyeing a new pair or rethinking an old favorite, it’s worth knowing the subtle (and not-so-subtle) signs your sandals might actually be too small. Let’s walk through them—because style should never come at the cost of comfort.
- Your toes are hanging over the edge. All toes should lay comfortably within the sandal.
- You can’t wiggle your toes freely. Your sandals shouldn’t nip your toes or make it difficult to move them.
- You get blisters or red marks when you wear them. Tight sandals lead to friction, which can lead to raw or tender skin.
Don’t have time to hunt down the new sandals right this second? There are ways to make your too-small sandals more comfortable until you can invest in a fresh pair. Here are a few of our favorite quick solutions:
- Add a little petroleum jelly to areas that chafe the skin. It’ll reduce friction and provide some much-needed relief!
- Invest in a slim gel insole. They’re great for taking pressure off the ball of your foot or heel.
- Use bandages proactively. If you know you’ll be on your feet for a long period of time, a strategically-placed band-aid can stop painful rubbing or chafing.
Signs Your Sandals Are Too Big
If your sandals are a bit too roomy, they could throw off your comfort and your confidence. Let’s take a closer look at the telltale signs your sandals are too generous in size.
- There’s a noticeable gap at the heel. If your heel is slipping out of the sandal or isn’t snug against the back, you likely need a smaller size.
- Your sandals make a clacking sound as you walk. Unless you’re wearing flip flops, your sandals shouldn’t make a hard slapping sound every time you take a step. If they do, it should mean they’re too big and not secure enough on your foot.
- You’re gripping with your toes to keep them on. A for effort, but those straps should be doing the heavy lifting!
Love your sandals, even though they’re just a tad too big? Try these quick tricks to stay comfy until you can swap them for a better fit.
- Get silicone strap cushions. If your straps are too loose, silicone cushions can add some grip and prevent them from slipping around. Plus, they’re discreet and easy to use.
- Don’t knock the sock look. Yes, some consider it a fashion faux pas, but wearing a pair of socks with your sandals can help fill the gap and keep your feet from sliding around.
- Use a small strip of double-sided tape on the bottom of your sandals to secure your foot in place. It’ll give you that extra grip you need to avoid any slipping while you’re out and about.
Tips for Getting the Proper Sandal Fit
Before you head off in search of your next favorite pair, let’s take a moment to recap what really makes a sandal fit just right.
- Try before buying: Even if you think you know your size, different brands and styles can fit differently—trying them on is the best way to know for sure.
- Check arch support: Especially for all-day wear, look for sandals with proper cushioning and arch support to avoid foot fatigue.
- Check for Foot Slippage: If your foot slides forward or the sandal feels too loose, it’s a sign the fit isn’t right. You want the sandal to stay in place while you walk.
- Test the Heel Fit: The back of the sandal should hold your heel firmly without slipping. If your heel lifts or slides out as you walk, it’s too loose.
- Check the strap placement: Straps should hug your feet without digging in or sitting awkwardly over bones or joints.
And, of course, trust your gut. If something feels even slightly off, it probably won’t get better over time. Don’t settle—there’s a better-fitting pair out there!

FAQs on How Sandals Should Fit
How should open toe sandals fit?
Your toes should rest comfortably within the edges of the sole—no spilling over or scrunching. Each toe should have a little wiggle room without feeling cramped or slipping forward.
Is it best to size up or down for sandals?
It’s usually a good idea to size up, especially if you're between sizes. Sandals tend to have more open space, and a slightly larger size can help avoid tight spots or uncomfortable rubbing. You can also look for wide width sandals instead, which offer a more generous fit.
How do I take care of my sandals?
Give them a good clean after wear, especially if they’ve been exposed to dirt or water. Store them in a dry, cool place and use leather conditioner if needed to keep them looking fresh.
