99% of People STILL Don’t Know the Basics of Fixing Bunions

One in three people have bunions ^[1]. Is that due to genetics—or is lifestyle to blame?

In this post, we’ll settle the bunion debate once and for all: how much do your genes really matter, and can simple lifestyle changes actually prevent – or even fix – bunions?

Genetic Factors: 4 Traits

If you have bunions, you may have one or more of these four genetic traits:

1. Ligament Laxity

Ligament laxity means the ligaments are too loose to stabilize the joints, making them hypermobile.

In the foot, this increases the chance of the great toe drifting inwards ^[2]. Signs include hypermobility in the hands, elbows, and knees.

Both my sister and I have this trait, yet neither of us has bunions. So it’s clearly not the whole story.

2. Wide Feet

Wide feet, or more specifically, wider intermetatarsal angles (between the first and second toe) are linked to bunions ^[3][4]. The reason for this link isn’t clear in the literature, but there are clues we’ll explore later on in this post.

3. Long Great Toe

Studies show that a longer great toe is linked to higher bunion risk ^[4][5].

One theory says it takes more pressure during walking, so the body angles it inward to shorter the lever-arm and reduce strain ^[6].

Another theory is that a great toe far longer than the neighboring toes loses their support and is more likely to drift.

Neither theory has strong evidence, but we’ll return to this with a stronger explanation.

4. Rounded Metatarsal Head

Rounded big toe joints allow more side-to-side movement, which reduces stability and makes the toe easier to misalign. Flatter joints limit this movement and offer more support ^[4][7].

Genetics vs. Lifestyle

So do these genetic traits determine whether you’ll develop a bunion?

Twin studies suggest otherwise.

A 2016 Korean study estimated that genetics accounted for 47% of bunion risk, though it did not consider footwear^[8].

A follow-up study^[9] did, comparing identical and fraternal twins while adjusting for shoe habits. The genetic difference wasn’t significant.

What mattered was footwear: narrow shoes nearly tripled bunion risk, making them a stronger predictor than genetics ^[9].

7 Lifestyle Factors That Affect Bunion Risk

1. Pointed Toe Box Shoes

The toes should be the widest part of the foot, but pointed shoes taper inward and push them out of alignment.

I tested this by cutting open a popular sneaker and measuring my toe angle—my great toe deviated 25°, nearly equal to a grade 3 bunion on the Manchester Scale ^[10].

This effect is worse with a longer great toe.

It’s no coincidence that bunions and bunionettes form exactly where pointed shoes narrow.

So, a long great toe may only increase bunion risk when paired with shoes that don’t accommodate it.

The fix: Choose barefoot-style shoes with a wide toe box, that match natural foot shape.

2. Shoe Width

Even foot-shaped shoes may not be wide enough for every foot, and when they aren’t, the toes get pushed out of alignment. For genetically wider feet, this happens more often—possibly explaining their link to higher bunion risk.

Supporting this, a study found bunions in 33% of shoe-wearers vs. just 2% of lifelong barefoot individuals, despite more wide feet in the barefoot group ^[11].

So the issue isn’t wide feet—it’s wide feet in shoes that can’t accommodate them.

To check if a shoe fits your foot width, remove the insole and stand on it with full weight. If you have a bunion, manually realign your great toe first—your toes should fit within the insole when properly aligned.

The fix: Visit our #Barefoot Shoe Finder and use the "X-wide" filter. This will show you brands that specifically make shoes with wider toe boxes.

3. Shoe Length

Wearing shoes that are too short raises bunion risk, even from an early age.

One study on preschoolers found a 14% increase in risk with shoes one size too small, and 30% with two sizes too small ^[12].

Another study revealed that 38.5% of schoolchildren wore shoes that were too short, leading to a higher prevalence of bunions in those children ^[13].

If toe restriction starts this young, it’s no surprise adults tolerate poor fit.

The fix: Shoes should be at least 10 to 12mm longer than your longest toe to allow for toe splay and daily swelling ^[14].

4. Raised Heels

Raised heels shift your weight forward, forcing your toes into the front of the shoe. Narrow shoes exacerbate this issue, adding even more pressure on the great toe ^[15].

A 2023 study found that even a 3 cm heel increased bunion angles. At 6 cm, the effect was much worse ^[16].

Heels serve no functional purpose in modern footwear. In fact, they were originally designed to help horseback riders stay in stirrups and later became fashion symbols.

The fix: Choose shoes with flat, zero-drop soles.

Shoe Checklist for Bunion Prevention

Look for shoes with:

• Flat (zero-drop) soles

• Toe boxes shaped like your foot

• Enough width and length for proper toe alignment

The fit should allow your great toe to stay aligned and your foot to splay naturally.

Other Contributing Factors

5. Weak Foot Arches

Weak arches cause overpronation, collapsing the foot inward and pushing the big toe into hallux valgus. Taking thousands of steps this way daily is a recipe for bunions.

Studies show a strong link between flat feet and bunions, with one finding bunions in all 32 women studied who had flat arches ^[17][18].

Without strong intrinsic foot muscles to support the arch, bunion prevention is almost impossible.

6. Tight Ankles

Limited ankle dorsiflexion restricts forward knee movement, so the body compensates by collapsing the foot into overpronation and using the midfoot as a “second” ankle joint ^[19].

This shifts excessive pressure to the great toe, which can lead to bunions over time.

This is a prime example of the body's deep interconnectedness—when restriction in one joint (the ankle) causes dysfunction elsewhere (the foot).

7. Weak Glutes

Weak glutes allow the pelvis to tilt forward (anterior tilt) and the knees to collapse inward (knee valgus), which flattens the foot arches and increases pressure on the great toe ^[20][21].

You can test this yourself:

• Stand with feet hip-width apart, toes straight.

• Let your knees drift inward—you’ll see your arches collapse and your big toes shift into valgus.

• Now, squeeze your glutes.

• You knees should move out, arches lift, and toes realign.

So you can see, glute strength plays a critical role in maintaining proper foot posture.

Why Are Bunions Often Only Seen on One Foot?

Genetics are symmetrical—yet many people have bunions on just one foot.

This suggests a functional cause rather than genetics.

Things like past injury, uneven mobility, or asymmetrical strength could all play a role in bunion development on one foot rather than both.

Thats why we use 10 functional tests in our #Member Consultations to identify these issues in our academy members. Your consultation will be delivered within 30 calendar days after we receive your complete intake form and all required assessment videos. If your purchase includes an earlier agreed delivery deadline, that deadline still applies.

We then use that holistic data to create a custom plan using 15-minute workouts and a library of over 100 corrective exercises to address any weaknesses.

How to Approach Genetic Risk

Genetic traits matter—but your choices matter most.

Blaming bunions on genetics while ignoring footwear or movement is like blaming sunburn on fair skin and refusing to wear sun protection.

Having a long toe or lax ligaments doesn’t guarantee a bunion. It just means you need to be more intentional with your shoes and your strength.

I have two of the four genetic risk factors, but don’t have bunions – Because I take the necessary precautions and have made the necessary fixes in my body.

The takeaway: use your genetic knowledge to guide better habits, not justify complacency.
