You might not think much about how your running shoes fit in the toe area—until problems start showing up. Numbness during runs. Black toenails after races. Blisters that never seem to heal. These aren't just inconveniences; they're your feet telling you something is wrong.
Most conventional running shoes taper toward the toe, squeezing your feet into a shape they weren't designed for. Over time, this compression can cause real damage. Here's how to tell if your shoes are too narrow—and what you can do about it.
The 7 Warning Signs
Toe Numbness or Tingling During Runs
If your toes go numb or you feel pins and needles during or after running, your shoes are likely compressing the nerves in your forefoot. This is especially common during longer runs when your feet swell.
Black Toenails (Runner's Toe)
Black or bruised toenails—medically called subungual hematomas—are often blamed on downhill running or long distances. But the real culprit is usually shoes that are too narrow, forcing your toes to repeatedly jam against each other or the front of the shoe.
Blisters on Sides of Toes
Blisters on the tops or tips of your toes might be a fit issue. But blisters on the sides of your toes—where they rub against each other—almost always indicate a too-narrow toe box.
Bunion Pain or Progression
If you have bunions (or bunion tendencies), narrow shoes will make them worse. You might notice increased pain on the inside of your big toe joint, especially during and after runs.
Forefoot Pain or "Hot Spots"
A burning sensation or concentrated pressure in the ball of your foot often indicates that your metatarsals (the long bones of your forefoot) are being squeezed together unnaturally.
Shoes Bulging at the Sides
Look at your running shoes from above. If the upper material is bulging outward at the widest part of your foot, or you can see the outline of your toes pressing against the mesh, your shoes are too narrow.
Toe Deformities Getting Worse
Hammertoes, claw toes, or overlapping toes that seem to be progressing—especially if they're worse than they were years ago—can often be traced back to years of wearing narrow footwear.

What to Do If Your Shoes Are Too Narrow
The Solution: Switch to Wide Toe Box Shoes
The most direct fix is switching to running shoes designed with anatomically-shaped toe boxes. These shoes follow the natural contour of the human foot—wider at the toes, narrower at the heel. Learn more about why wide toe box matters for foot health.
What to look for:
- Toe box that matches or exceeds the width of your forefoot
- Rounded or foot-shaped toe profile (not pointed or tapered)
- Enough vertical room that your toes don't touch the top of the shoe
- About a thumb's width of space between your longest toe and the end of the shoe
Important note: When you first switch to wide toe box shoes, they might feel "loose" or "sloppy" because you're used to the compressed feeling of narrow shoes. This is normal. Your feet have adapted to being squeezed; it takes time to adjust to having room. Give it a few runs—most people never want to go back. Read our transition guide for more tips.
Don't Confuse "Wide" Sizes with Wide Toe Boxes
Ordering a "wide" (W, 2E, or 4E) version of a conventional running shoe is not the same as getting a shoe with a wide toe box. Wide sizes simply scale the entire shoe up—including the heel, which then becomes too loose for most people.
A true wide toe box shoe is designed anatomically: it's wide where your foot is wide (the toes) and appropriately fitted where your foot is narrow (the heel). This provides the room where you need it without sacrificing fit elsewhere. Have questions about fit? Check our FAQs.
The Long-Term Benefits
Switching to properly-shaped footwear doesn't just eliminate current symptoms—it may help prevent future problems:
- Bunion prevention: Research suggests that narrow footwear contributes to hallux valgus development. Giving your big toe room to stay aligned may slow or prevent progression.2
- Better balance: When your toes can spread, you have a wider base of support. Studies show this improves stability.6
- More efficient running: Proper toe splay allows for better push-off mechanics, potentially improving running economy.
- Healthier feet long-term: Your feet will thank you in 20 years. Many age-related foot problems have their roots in decades of wearing ill-fitting shoes.
