The Bunion Blog: What’s Really Causing Your Bunions (and What You Can Do About It)
Bunions, toe surgery, and foot pain have been hot topics in our clinic lately, so it felt like the right time to dig into bunion causes and treatment—a condition that sends a lot of people straight to a surgery consult. Many patients assume their bunions are “just genetic” or that the damage can’t be reversed. The good news: that’s not the full story, and there’s a lot you can do to support your feet. Let’s break down what’s actually happening, explore the common causes of bunions, and discuss treatment options for bunions that may help address foot pain and support healthier foot function.
What Is a Bunion, Really?
A bunion isn’t just a random bump — it’s your body’s response to repeated stress on the foot. There are two main mechanisms behind bunion formation:
- Improper loading of the MTP joint (the first Metatarsal Phalangeal Joint)
- Hallux Valgus — lateral displacement of the big toe
Both sound clinical, so here’s what they mean in plain terms.
Cause #1: Overloading the MTP Joint
The MTP joint forms the ball of the foot — essentially the “knuckle” of your big toe. Every step you take sends a significant amount of body weight through this joint. Flatten the arch of the foot, or add a heeled shoe into the mix, and that force can double or triple.
When this joint is chronically overloaded, the body responds by laying down extra bone density — a bone spur — to help support the added force. Over time, that adaptation shows up as a bunion.
Cause #2: Hallux Valgus (The Big Toe Drift)
The second pathway is Hallux Valgus, where the big toe gradually angles and curves inward toward the smaller toes. Beyond making walking uncomfortable, this drift creates significant torque and pressure on the inner edge of the MTP joint.
The most common drivers of this toe drift are:
- Improper gait patterns
- Footwear — particularly narrow toe boxes
Our feet naturally need more width at the front than most shoes provide. When the toes are consistently squeezed into a narrower space than they’re built for, the big toe gets pushed inward — setting the stage for a bunion.
Can You Reverse Bunion Damage?
You don’t need to throw out every pair of shoes and go barefoot (especially in a cold, damp climate). Finding footwear with a truly wide toe box can be difficult, but there are still effective ways to counteract the damage.
1. Toe Stretches
Start simple:
- Low-tech: Use your fingers to gently stretch the space between your toes.
- High-tech: Wear toe spreaders at night while sleeping.
If you try toe spreaders, ease into them. Avoid wearing them while weight-bearing, and start with just a few hours a night, gradually working up to wearing them through the night.
2. Strengthening the Intrinsic Foot Muscles
No gym equipment needed for this one. With your feet flat on the floor, try lifting just your big toe off the ground while keeping the other toes flat. It’s harder than it sounds — roughly half of people can’t do it on the first try. If that’s you, keep practicing; the strength builds with consistency.
Toe Box Space: A Visual Reality Check
Our natural toe splay takes up more room than the average shoe’s toe box allows. Take a look at your own shoes — is there room for your toes to lie flat and spread naturally, or are they being pushed together?
Final Thoughts
Bunions often feel like an inevitable, genetic sentence — but footwear, gait, and joint loading all play a major role in how they develop and progress. Toe stretches and intrinsic foot strengthening are simple, accessible starting points for supporting healthier foot mechanics.

Frequently Asked Questions (FAQ)
Q: Are bunions purely genetic? A: Genetics can play a role in foot structure, but footwear choices, gait patterns, and joint loading are major contributing factors. This means lifestyle changes can help manage and even slow bunion progression, not just genetics alone.
Q: What are the two main causes of bunions? A: Bunions typically form from either improper loading of the MTP (Metatarsal Phalangeal) joint, or Hallux Valgus, which is the gradual inward drift of the big toe toward the other toes.
Q: Can toe stretches actually help with bunions? A: Yes. Stretching the space between your toes — whether manually with your fingers or using toe spreaders — can help counteract the tightening and drift that contributes to bunion formation.
Q: What is the big toe lift exercise, and why does it matter? A: This exercise involves lifting your big toe off the floor while keeping your other toes flat. It targets the intrinsic muscles of the foot, which help stabilize the arch and MTP joint. About half of people initially struggle with this movement.
Q: How does footwear contribute to bunions? A: Narrow toe boxes and high heels squeeze the toes into a smaller space than they naturally need, pushing the big toe inward and increasing pressure on the MTP joint — both of which accelerate bunion development.
Q: Do I need surgery to fix a bunion? A: Not necessarily. While severe cases may require surgical intervention, many people can manage symptoms and slow progression through toe stretches, strengthening exercises, and better-fitting footwear. Consult a healthcare provider for guidance specific to your situation.
Q: Where can I learn more about foot health and bunion prevention? A: Katy Bowman’s resources are a great starting point, and the team at Jewell Chiropractic is available to answer questions about foot pain and bunion care.
