Hallux Valgus: Causes, Symptoms, Treatment, and Prevention Tips
Hallux valgus is a common foot deformity that can be painful and limit daily activities. Here, you’ll learn, among other things, how to prevent it early on and what treatments can help you besides surgery.
Hallux valgus—better known to many as a bunion—is one of the most common foot deformities worldwide, and according tothe *Deutsches Ärzteblatt*, it affects about one in three to four people, primarily middle-aged and older women. This deformity can not only lead to pain and limited mobility but also significantly impact quality of life. Those affected often ask: What causes hallux valgus? What options are there besides surgery? And how can I prevent it?
In our article, you’ll learn everything you need to know about causes, symptoms, conservative and surgical treatment options, and prevention. We’ll also show you how you can actively contribute to your foot health through exercises and assistive devices.
Key takeaways
- Hallux valgus affects 23 to 35 per cent of the population, making it the most common deformity of the forefoot (Wülker & Mittag, 2012).
- Conservative measures such as splints, insoles, suitable footwear and exercises may ease symptoms – but they do not correct the deformity itself.
- Surgery can reduce pain in a clinically meaningful way; in the Cochrane review, however, there was hardly any difference in quality of life compared with conservative treatment (Dias et al., 2024).
- There is no evidence that the deformity regresses without surgery. If you would like it corrected, you need a medical assessment.
- Prevention mainly comes down to footwear, foot muscle training and weight – but these cannot offset a genetic predisposition.
What is hallux valgus?
Hallux valgus refers to a misalignment of the metatarsophalangeal joint of the big toe. In this condition, the big toe gradually deviates outward at the metatarsophalangeal joint, while the first metatarsal bone shifts inward. This alters the position of the entire joint and causes a noticeable bulge to form at the ball of the foot, which is not only visually noticeable but is also often red, swollen, and painful. Over time, this change can lead to pressure points, inflammation, and problems with the foot’s rolling motion.
Typical characteristics:
- Misalignment of the big toe
- Prominent bunion
- Pain when walking or wearing tight shoes
- Altered gait
- Balance problems
Important: Hallux valgus should not be confused with hammertoe or claw toe. These conditions affect other joints of the foot.

Causes and Risk Factors
The development of hallux valgus is complex and is usually caused by several factors:
- Genetic predisposition: Hallux valgus often runs in families.
- Footwear: Tight, pointed, or high-heeled shoes exert pressure on the forefoot and contribute to the deformity.
- Gender and hormones: Women are affected significantly more often—presumably due to a combination of weak connective tissue and footwear trends.
- Excess weight: Every extra kilogram puts additional strain on the ankle joints.
- Foot deformities: Flat feet or splayfoot increase the risk of developing the condition.
- Lack of exercise: Weak foot muscles cannot adequately stabilize the forefoot.
- Hip misalignments: Imbalances in the hip and pelvic area can extend downward and cause improper weight distribution on the feet.
- Age: The risk increases with age, as the elasticity and stability of connective tissue decline.
- Rheumatic diseases: Inflammatory joint diseases such as rheumatism or osteoarthritis can weaken the structure of the forefoot.
- Occupational stress: Standing for long periods or working in tight safety shoes can increase pressure on the forefoot.
- Pregnancy: Hormonal changes cause the connective tissue to soften, which can contribute to misalignments.
Symptoms and Diagnosis
Hallux valgus usually develops gradually over many years. Initially, there are only mild pressure points or blisters on the bunion, which often occur after prolonged walking or when wearing tight shoes. Many people do not take these early signs seriously, as the symptoms initially occur only occasionally. Over time, however, the deformity can worsen, leading to increased pain and limitations in daily life.
Common symptoms include:
- Pain in the area of the big toe bump, especially when wearing tight or high-heeled shoes
- Redness, swelling, or inflammation at the ball of the foot due to constant friction
- Pressure points, calluses, or corns caused by improper weight distribution
- increasingly limited movement of the big toe, which makes it difficult to roll the foot forward while walking
- a change in the biomechanics of the entire foot, which can lead to pain in the knee, hip, or even the back over time
The diagnosis is usually made by an orthopedist or foot specialist. In addition to a thorough visual examination and palpation, X-rays may be necessary. They show the extent to which the big toe deviates from its normal axis and provide information about the severity of the deformity. Based on this, doctors decide which treatment—conservative or surgical—is most appropriate.

Conservative Therapy & Assistive Devices
Many people affected by this condition would like to avoid or delay surgery. In such cases, conservative measures are recommended to relieve symptoms and slow the progression of the condition:
- Hallux valgus splints: These realign the big toe into a straight position. They are particularly helpful at night when combined with active treatment measures.
- Activating insoles: Unlike traditional orthopedic insoles, which support the arch of the foot and can cause it to become even weaker, activating insoles strengthen and challenge the foot muscles.
- Special Shoes: Soft, wide shoes with plenty of room in the toe area and as little heel height as possible reduce pressure.
- Exercises: Regular exercise strengthens the muscles of the feet and toes and helps regulate the plantar fascia (e.g., toe curls or foot mobilization).
- Fascia Training: Using the BLACKROLL® BALL or the MINI fascia roller, you can release the plantar fascia and activate the foot muscles.
- Pain management: Cold therapy, anti-inflammatory ointments, or pain relievers can help with acute symptoms.
Surgical Treatment & Procedure
If conservative methods such as splints, orthotics, special footwear, or exercises are no longer sufficient and symptoms continue to worsen in daily life, surgery may be necessary.
Orthopedists often recommend surgery, particularly when pain persists despite treatment, the deformity is clearly visible, or mobility of the big toe is severely restricted. Chronic inflammation or stress-related issues affecting other joints are also important reasons for surgery.
When is surgery advisable?
- Severe pain despite conservative treatment
- Significant misalignment with limited mobility
- Inflammation, swelling, or pressure sores that do not heal
- Difficulty with everyday activities, such as walking or exercising, making them nearly impossible
Common Surgical Methods
There is no single “standard” hallux valgus surgery; rather, there are various procedures that are selected based on the severity of the condition, individual symptoms, and foot anatomy. The goal is always to permanently correct the deformity, relieve pain, and restore foot function. The most common surgical methods include:
- Chevron or Scarf osteotomy: The metatarsal bone is cut and realigned so that the toe is straight again.
- Soft-tissue correction: In this procedure, tendons, muscles, and the joint capsule are adjusted to hold the big toe in its corrected position.
- Combination procedures: Bony and soft-tissue corrections are often combined to achieve a permanently stable result.
The procedure is typically performed using minimally invasive or open surgical techniques under general or regional anesthesia. The surgery usually lasts between 30 and 90 minutes, depending on the procedure.
Risks and Recovery
As with any surgery, there are certain risks involved, such as infections, wound healing complications, swelling, or the recurrence of the deformity.
However, modern surgical methods have a high success rate, and most patients are pain-free and able to resume normal activities after a few months.
Costs
The costs are generally covered by public or private health insurance, provided there is a medical necessity. Those who wish to undergo the surgery for purely cosmetic reasons must, in most cases, pay for it themselves.
Aftercare & Rehabilitation
Postoperative care following hallux valgus surgery is crucial for achieving complete healing, reducing pain, and preventing the deformity from recurring. The more carefully rehabilitation is carried out, the better the long-term results will be in terms of mobility, stability, and ability to perform daily activities. Patients can support their rehabilitation with certain measures, including:
1. Special shoes and weight-bearing relief
Immediately after surgery, patients typically wear special shoes or orthopedic splints for about 4–6 weeks. These:
- Relieve pressure on the ball of the big toe and the metatarsophalangeal joint
- Protect the metatarsal bones during healing
- Limit stress and prevent unwanted movements
In the first few days, partial weight-bearing or walking with forearm crutches is often necessary to protect the foot.
2. Physical Therapy and Mobilization
Physical therapy usually begins after discharge from the hospital and focuses on:
- Gentle mobilization of the metatarsophalangeal joint of the big toe
- Strengthening the muscles of the foot and lower leg
- Improvement of joint function and gait
- Prevention of related problems such as splayfoot or knee strain
Regular physical therapy promotes blood circulation, reduces swelling, and speeds up healing.
3. Lymphatic Drainage and Swelling Reduction
Swelling often occurs after surgery and can persist for several weeks.
Manual lymphatic drainage or cold therapy can help reduce fluid buildup and alleviate pain.
4. Exercises for the Foot Muscles
The stabilizing foot muscles and toe mobility can be gradually rebuilt through gentle exercises. We recommend mobilization exercises for the toes—including gentle spreading and flexing movements—as well as strengthening exercises for the toe and foot muscles to improve balance.
Those affected should perform these exercises gently and regularly to support the healing process without putting strain on the surgical site.
5. Patience and Long-Term Recovery
A full recovery after hallux valgus surgery often takes several months. Important points for patients to keep in mind:
- Gradually increase activity; avoid overexertion
- Wear shoes with a wide toe box to avoid pressure points
- Take pain seriously and see a doctor if you have any problems
With consistent follow-up care, targeted physical therapy, and exercise-based training, it is possible to maintain foot function in the long term, reduce pain, and restore mobility in daily life.
Prevention & Tips for Foot Health
The risk of developing hallux valgus cannot always be ruled out completely, especially where genetic factors play a role. Even so, a conscious, healthy lifestyle can help to slow the development or progression of the deformity considerably and support your foot health overall. Our tips:
1. Choosing your shoes
The right footwear plays a central role. Shoes that are too tight, pointed or high-heeled put pressure on the big toe and encourage deformities. Instead, your shoes should meet the following criteria:
- Wide toe box: Your toes have enough room to move freely.
- Flat or moderate heel height: Ideally a heel of no more than 2–3 cm, or better still 0 cm, as with barefoot shoes.
- Soft, flexible material: Adapts to the shape of your foot and reduces friction.
- Good cushioning: Relieves the big toe joint and the metatarsal bones.
Tip: If you walk or stand a lot, check how your shoes fit several times a day and watch for pressure points, to avoid blisters, calluses or inflammation.
2. Regular training and foot exercises
Strong foot muscles and flexible tendons are essential for stabilising the foot’s structure. We recommend:
- Walking barefoot on soft surfaces: encourages natural foot movement.
- Targeted foot exercises: Spreading your toes, gripping with your toes or picking up small objects with your toes. In our article Foot exercises: the best exercises for healthy feet you will find a detailed exercise programme for the feet.
- Fascia training: Loosening the sole of the foot with a roller or ball.
- Mobilising the big toe joint: gentle circling of the big toe to maintain mobility.
BLACKROLL® tip: The BLACKROLL® BALL 08 or the foam roller MINI are ideal for mobilising the sole of the foot every day. Simply roll from heel to ball of the foot with light pressure to release fascial adhesions and support circulation.
3. Weight management
Being overweight increases the load on your feet, particularly around the midfoot and the ball of the foot. Even a few kilos less can noticeably reduce the pressure forces and counteract deformities.
4. Foot care and mindfulness
Regular foot care helps to prevent discomfort. This includes gently removing hard skin, stretching and massaging your toes and the balls of your feet, and treating pressure points early to prevent inflammation.
People with a family history in particular should check their feet regularly and act early at the first signs of redness, swelling or pain.
5. Lifestyle and everyday tips
- Wear different shoes through the week to spread the load
- Barefoot or minimalist shoes support the natural foot muscles
- Take short breaks during long periods of standing or walking to relieve pressure points
- Targeted strengthening of the foot and leg muscles through regular training
With these measures you can support your foot health in the long term, help prevent discomfort and slow the development of hallux valgus.

Conclusion
Hallux valgus may be a common foot deformity, but that doesn’t mean you’re powerless. With the right measures, you can actively promote your foot health and effectively reduce pain. Even small changes in your daily routine—such as wearing appropriate footwear, walking barefoot on natural surfaces, doing targeted foot exercises, and using splints or insoles—can make a big difference.
Even though surgery may be necessary in advanced cases, the path to that point is no cause for concern: With early prevention and targeted exercises, many symptoms can be treated conservatively. Regular exercise, strengthening the foot muscles, and mobilizing the plantar fascia help make your feet more resilient again and make walking feel more natural.
Step by step, you can improve your foot health, reduce pain, and regain a better quality of life. Your foot health is in your hands—and every small step counts.
