Bunion insoles: what they can and cannot do

A bump on the inside of your foot, right at the joint of your big toe. At first you barely notice it, but over time your big toe drifts towards your other toes and your shoes start to pinch. Almost everyone with a bunion eventually asks the same question: do insoles help?

We would rather give you the honest answer straight away. An insole does not undo a bunion. The misalignment of the joint will not disappear because of a sole in your shoe. What bunion insoles can do: support your arch and spread pressure more evenly across your forefoot, so the painful joint carries less load. Many people find that this makes walking and standing less painful. Below you will read how a bunion develops, what you can do yourself, and when it is time to see a doctor.

What is a bunion (hallux valgus)?

Hallux valgus is the medical name for what most people simply call a bunion. It affects the joint where your big toe meets the metatarsal bone, known as the first metatarsophalangeal joint.

With a bunion, your big toe gradually turns outwards towards your second toe, while the metatarsal bone behind it shifts inwards. The joint between them moves out of line and starts to stick out on the inside of your foot. That protruding part is the bump you see and feel: it is not extra bone that has grown there, and certainly not a tumour. The bursa around that spot can become irritated, leaving the area red, warm and tender. That explains why the complaint feels much worse in some weeks than in others.

A bunion develops slowly, often over years, and in the early stages it is purely cosmetic. As the alignment changes, your foot rolls through differently and pressure shifts towards your second and third toes. This is why a bunion often comes with other forefoot complaints.

What causes a bunion?

There is rarely one single culprit: it is almost always a combination of predisposition and load. These are the factors that play a role most often.

• Genetics. The single most important factor: the shape of your foot bones and the firmness of your ligaments are largely inherited. If bunions run in your family, your chances are clearly higher.
• A collapsed arch. With flat feet or fallen arches your foot rolls further inwards with every step, which puts extra rotational force on the joint of your big toe.
• Overpronation. If your foot rolls too far inwards as you push off, your big toe gets pushed outwards with every stride. Read more about recognising overpronation.
• Narrow or pointed shoes. Shoes probably do not create a bunion out of nowhere, but they do make an existing predisposition show up faster. High heels also push your weight forwards onto the forefoot.
• Being female. Bunions are clearly more common in women, which is linked to softer connective tissue and to the footwear more often worn.
• Age and mileage. The more kilometres your feet cover, the greater the chance that the alignment slowly changes.
• Rheumatic conditions and hypermobility. Joint inflammation or very loose ligaments give the joint less to hold on to.

Most of these factors are outside your control. That is exactly why treatment does not aim to reverse the alignment, but to reduce the load.

Symptoms: how to recognise it

A bunion is usually easy to see, but the complaints go beyond the bump itself. Look out for these signs:

• A visible bump on the inside of your foot, at the joint of your big toe.
• A big toe that points sideways towards your second toe, sometimes even sliding under or over it.
• Pain in shoes, especially closed models with a narrow toe box. Barefoot it is often much better.
• Redness, warmth or swelling around the bump.
• Calluses or a corn on the bump or between your first and second toe.
• Pain under the ball of your foot, because your big toe does less work and your other toes take over.
• Stiffness in the joint, which makes rolling through your step less smooth.
• Trouble buying shoes, because your foot has become wider at the front.

When it might be something else. If the joint is stiff and painful but your toe is still straight, it could be hallux rigidus, a form of arthritis in that same joint. Sudden, severe, throbbing pain that often starts at night can point to gout: that belongs with your doctor. If the pain sits mainly under the ball of your foot, have a look at metatarsalgia. Burning pain with tingling between the toes fits better with a pinched nerve, such as a Morton's neuroma.

What can you do yourself?

You cannot correct the alignment of the joint yourself. You can absolutely influence the load on that joint and the pain that comes with it. Here is what helps most.

Choose the right shoes. By far the most important step. Go for a wide, round toe box where your toes keep their natural spread; pointed models push your big toe in exactly the direction you want to avoid. Watch the heel height too: the higher the heel, the more weight lands on your forefoot. Buy shoes at the end of the day, when your feet are at their widest.

Support your arch with a good insole. Here it is important to be honest again about what you can expect. What an insole does not do: it will not push your big toe back, it will not shrink the bump, and it will not cure the condition. Anyone who promises that is promising too much. What an insole can do: support your arch so your foot collapses inwards less, and spread pressure more evenly across your forefoot so the painful joint is relieved. Many people find that walking and standing hurt less, and the overload that can make the complaint worse is reduced. That is not a cure, but in daily life it often makes a real difference.

Try a toe spacer. A small silicone spacer between your big toe and second toe keeps them apart and prevents rubbing and pressure spots. Do not expect lasting correction: as soon as you take it out, your toe returns to its own position.

Know what a night splint does. A night splint pulls your big toe into a straighter position while you sleep, which some people find pleasant in the morning. There is no evidence that it permanently changes the alignment in adults, so treat it as a comfort aid rather than a corrective device.

Mind your weight and your skin. Every step loads your forefoot with a multiple of your body weight, so less weight means less pressure on a joint that already has plenty to deal with. Have calluses on the bump removed by a podiatrist rather than cutting them yourself, and if the area is red and swollen, cool it for ten minutes a few times a day.

3 exercises for bunions

Exercises will not straighten your toe, but they do keep the joint mobile and strengthen the small muscles that stabilise your forefoot. Take it gently and stop if you feel sharp pain; five to ten minutes a day is enough.

1. Spreading the big toe

1. Sit upright with both feet flat on the floor.
2. Keep your other toes relaxed and move only your big toe outwards, away from your second toe.
3. If that does not work straight away, guide it in the right direction with your hand.
4. Hold for five seconds, release and repeat ten times per foot.

2. Towel scrunches

1. Lay a towel flat on the floor and place your bare foot on it.
2. Grip the fabric by curling your toes and pull the towel towards you, keeping your heel on the ground.
3. Keep going until the whole towel is under your foot, then repeat three times per foot.

3. Mobilising the joint

1. Cross your ankle over your other knee.
2. Steady your forefoot with one hand and take hold of your big toe with the other.
3. Move the toe gently up and down fifteen times, until you feel a light stretch but no pain.
4. Then make ten calm circles in each direction.

When should you see a doctor?

A mild bunion without pain does not need treatment. Do book an appointment with your doctor if you recognise any of these points:

• Pain that limits your daily life, for example when walking, working or playing sport.
• Pain that persists despite good shoes and insoles.
• Red, warm and swollen tissue that does not settle within a few days, especially with a fever.
• An open wound on the bump, or callus that starts to crack.
• Rapidly increasing misalignment, or a toe that slides under or over your second toe.
• New complaints in your other toes, such as hammer toes.
• Diabetes, rheumatic disease or reduced sensation in your feet: any pressure spot is then a reason to get it checked.
• Sudden, severe, throbbing pain without an obvious cause. Always have this assessed.

And surgery? Surgery only comes into play when the pain genuinely limits how you function and non-surgical measures do not help enough. A bump you dislike the look of but that does not hurt is not a medical reason to operate. During surgery, an orthopaedic surgeon realigns the bone and the toe, for example by cutting the metatarsal bone, shifting it and fixing it in place. Which technique suits you depends on how severe the misalignment is. Bear in mind that recovery takes months. Your doctor can refer you and weigh up with you whether that moment has come.
