You’ve worn the same shoe size since high school. You grab a size 9, slide it on, and it fits. Or so it seems. But by the end of the day, your toes are cramped, your heels are sore, and you’re wondering why that “perfect fit” is failing you. The truth is, your go-to shoe size might be deceiving you—and your feet are paying the price.
Shoe sizing is far from a universal standard. Brands vary widely, feet change over time, and many people are wearing the wrong size without even realizing it. Ill-fitting shoes don’t just cause discomfort—they can contribute to long-term foot problems like bunions, corns, hammertoes, and chronic pain.
It’s time to take a closer look at the myths around shoe size, the factors that influence proper fit, and how to make sure your footwear truly supports your foot health.
The Myth of the “Fixed” Shoe Size
Most of us treat our shoe size like our blood type—unchanging and consistent. But in reality, your shoe size can fluctuate throughout your life. Factors like age, weight gain, pregnancy, injuries, and even gravity can change the length, width, and shape of your feet.
As we age, the tendons and ligaments in the feet naturally lose elasticity, which causes the arches to flatten. This can make your feet longer and wider than they were a few years ago. Foot swelling, fluid retention, and structural changes also play a role in altering your fit.
In other words, just because a size 8 fit you five years ago doesn’t mean it fits you now.
Why Shoe Sizes Aren’t Standard
One of the biggest frustrations when shopping for shoes is inconsistency across brands. A size 9 in one brand may feel like a size 10 in another. Some European sizes don’t convert cleanly to U.S. sizes. Even within a single brand, different styles may have slightly different shapes and fits.
That’s because manufacturers use different shoe lasts (the mold used to shape a shoe), materials, and design priorities. A running shoe might have a roomy toe box and structured heel, while a dress shoe may taper at the toe and feel snug even at the same labeled size.
This lack of standardization makes it critical to try shoes on—or at the very least, know your actual foot measurements—rather than relying solely on the number on the box.
Width Matters More Than You Think
Another common sizing issue is ignoring foot width. Many people have wide or narrow feet and don’t realize that shoe width plays just as important a role in fit as length. Wearing a shoe that’s too narrow can lead to bunions, pinched nerves, corns, and chronic pain. Wearing one that’s too wide can cause instability and friction blisters.
Shoe width options are often limited in brick-and-mortar stores, leading people to settle for whatever “kind of fits.” But squeezing into the wrong width, especially over time, leads to big problems. Brands that offer wide or narrow sizing (or that allow for custom insoles) can provide a much better fit than trying to force your foot into a standard mold.
The Problem with “Breaking In” Shoes
Many people assume a new pair of shoes just needs to be broken in before they feel comfortable. While it’s true that some materials soften over time, shoes should never cause pain, blisters, or pressure when first worn. That’s a red flag that the size—or shape—is wrong for your foot.
If you find yourself avoiding a pair of shoes until they “loosen up,” you’re probably forcing your feet to adapt to the shoe, instead of the other way around. That can lead to lasting damage and reinforce poor foot mechanics.
Signs Your Shoes Don’t Actually Fit
Even if your shoes aren’t tight, they may still be causing harm. Here are a few subtle red flags:
-
Toes that touch or press against the front of the shoe
-
Heel slippage or rubbing when walking
-
Tingling or numbness in your toes or forefoot
-
Blisters, corns, or calluses in the same spots
-
Fatigue in the balls of your feet after short walks
-
Regular foot or lower back pain by the end of the day
These are all indicators that your current shoe size—or style—isn’t working for you.
How to Measure Your Feet (Properly)
The best way to get an accurate understanding of your true shoe size is to measure your feet while standing, at the end of the day, when they’re naturally at their largest. Use a Brannock device if you have access to one, or measure length and width with a ruler on a flat surface.
Make sure to measure both feet, as most people have one foot slightly larger than the other. You should buy shoes that fit your larger foot comfortably without squeezing or slipping.
Also consider the type of socks you’ll wear with the shoes. Thicker socks may require slightly more space. And if you use orthotics, always bring them with you when shopping for shoes—they can significantly alter the fit.
Why the Right Fit is Worth the Effort
Wearing the correct shoe size is about more than comfort—it’s about long-term health. The wrong fit can lead to toe deformities, joint misalignment, poor posture, and overuse injuries. On the flip side, the right shoe can prevent pain, improve performance, and support healthy movement from the ground up.
Choosing supportive footwear and getting regular foot evaluations is especially important for people with diabetes, arthritis, or previous injuries. It’s also critical for children, whose feet are still developing and highly vulnerable to long-term damage from poor footwear choices.
When to See a Foot Specialist
If you’re constantly dealing with foot pain, blisters, or shoes that never seem to feel quite right, it may be time for a professional assessment. A podiatrist can evaluate your foot structure, gait, and footwear choices to recommend better options—and even custom orthotics if needed.
At Bellagio Foot & Ankle, we help patients take the guesswork out of shoe sizing. From in-office measurements to personalized footwear recommendations, our team is here to make sure every step you take is a step toward better health.
Don’t Let a Number Define Your Fit
Your feet are unique—and your shoes should reflect that. If you’ve been trusting a single number to guide your footwear choices, it might be time to rethink how you shop and how you walk.
