What Is a Bunion? Bunions are a common foot issue we see at Ripple Podiatry, and in this post, I’m diving into exactly what a bunion is, how it develops, and why early intervention is so important.

What Is a Bunion?
A bunion occurs when the big toe starts to angle towards the smaller toes. As this happens, the joint at the base of the big toe opens up and starts to dislocate (or sublux), putting increasing pressure on the side of the foot.
On the outside of that joint, there’s a small fluid-filled sac called a bursa. Its job is to protect the joint and nerve from external force—but due to the constant internal pressure from the misalignment, it becomes irritated and inflamed. Over time, this bursa can become hardened and enlarged, making the bunion more visible and painful.
Why Do Bunions Develop?
A major contributor to bunion formation is biomechanics—often passed down through our genes. If your parents walked a certain way, you’re likely to inherit a similar gait.
For example, if instead of pushing off through your toes you pivot off the side of your foot, you’re shifting pressure to the outside of the big toe joint. Multiply that by 3,000 to 7,000 steps per day, every day for years—and it’s no surprise that the joint starts to shift and break down.
Bunion Progression: It Doesn’t Just Stop at the Toe
As the bunion progresses:
-
The big toe pushes across, causing the second toe to shift up or down to make space.
-
The joint becomes arthritic, limiting movement and increasing pain.
-
Your entire walking pattern starts to change. The ankle, knee, hip, and even your back may need to compensate.
-
You may experience rotational strain, nerve pinching, or develop neuromas (painful nerve growths) in the smaller toes.
Early Signs to Look For
Before you even see that toe shift across, you might notice:
-
Stiffness in the big toe joint
-
Reduced flexibility in the forefoot
-
Discomfort when walking, especially with tight shoes
These are all red flags that your bunion is developing. If left untreated, what starts as a minor cosmetic issue can evolve into a serious mobility and posture problem.
Don’t Wait – Get Assessed Early
The most important takeaway? Early intervention matters.
At Ripple Podiatry in Waikato, we recommend you get checked as soon as you notice changes in your toe alignment or foot pain. In upcoming videos, I’ll be covering bunion prevention and what we can do to help you avoid surgery and reduce your symptoms.
