What Does Clubfoot Look Like on a Baby?
If you've just been told your baby has clubfoot, or you're examining your newborn's feet and something doesn't look quite right, you're probably searching for answers about what clubfoot looks like on a baby. Clubfoot (medically known as congenital talipes equinovarus or CTEV) is one of the most common birth differences in the UK, affecting approximately 1 in 1,000 babies. It has a very distinctive appearance, and knowing what to look for — and what distinguishes it from other, less serious foot positions — can help put your mind at ease or prompt you to seek the right help.
This guide describes the visual signs of clubfoot in detail, explains how it differs from positional talipes (a much milder and self-correcting condition), and shows you what to expect as treatment progresses and the foot gradually transforms.
The Classic Appearance of Clubfoot at Birth
Clubfoot has a characteristic appearance that is usually immediately recognisable to medical professionals. When you look at a baby with clubfoot, you'll notice several distinct features:
The Foot Points Downwards (Equinus)
The most obvious feature is that the foot is pointed downwards, as though the baby is trying to stand on tiptoe. This is called equinus, and it occurs because the Achilles tendon at the back of the ankle is abnormally tight and shortened. The foot cannot be pulled up into a normal position — it remains fixed in this pointed-down orientation.
The Foot Turns Inwards (Varus)
The heel and sole of the foot turn inwards, so that the sole faces towards the other leg rather than pointing downwards towards the ground. In severe cases, the sole may face almost directly upwards. This inward turning is called varus of the hindfoot, and it gives the foot a distinctive twisted appearance.
The Front of the Foot Curves Inward (Adduction)
The front half of the foot (the forefoot) curves inwards towards the midline of the body. This is called forefoot adduction or metatarsus adductus. It creates a C-shaped or kidney-bean curve when you look at the sole of the foot from below. The toes point towards the other foot rather than straight ahead.
A Deep Crease on the Sole
Many babies with clubfoot have a deep crease across the middle of the sole of the foot. This crease results from the forefoot being pulled inwards, and it can be quite pronounced. There may also be a crease at the back of the ankle where the foot is held in its downward position.
The Calf Muscle Appears Thinner
On the affected side, the calf muscle is typically smaller and less developed than on the unaffected side. This is one of the more subtle signs and is more noticeable in babies with unilateral (one-sided) clubfoot. This calf size difference often persists to some degree even after successful treatment, though it rarely causes functional problems.
The Foot May Appear Shorter
The affected foot is often slightly shorter (typically 1-1.5cm) than an unaffected foot. This size difference is present from birth and usually persists into adulthood, though it's rarely noticeable in shoes. In bilateral clubfoot, both feet may be slightly smaller than average.
Severity: Mild to Severe Clubfoot
Not all clubfoot looks the same. The severity can range from mild to severe, and clinicians use scoring systems to classify and track it.
The Pirani Scoring System
The most commonly used system in the UK is the Pirani score, which assesses six clinical features (three in the hindfoot and three in the midfoot) and gives a score from 0 to 6. A higher score indicates more severe deformity:
- Score 0-1: Mild clubfoot — the foot may look only slightly turned in, with reasonable flexibility
- Score 2-3: Moderate clubfoot — clear inward turning and resistance to correction
- Score 4-6: Severe clubfoot — the foot is rigidly held in a markedly abnormal position, with deep creases and significant resistance to manipulation
Importantly, the Pirani score does not predict the final outcome of treatment. Babies with high initial scores can achieve excellent results with the Ponseti method. The score is used primarily to track progress during treatment and to guide decisions about whether an Achilles tenotomy is needed.
Clubfoot vs Positional Talipes: Knowing the Difference
One of the most common sources of confusion for parents is the difference between true clubfoot (structural talipes equinovarus) and positional talipes (postural talipes). They can look similar at first glance, but they are very different conditions with very different outlooks.
How to Tell Them Apart
| Feature | True Clubfoot (CTEV) | Positional Talipes |
| Rigidity | Foot is rigid and resists correction | Foot can be gently moved to normal position |
| Creases | Deep creases on sole and/or heel | Normal skin creases |
| Calf size | Calf may be smaller on affected side | Calves are symmetrical |
| Self-correction | Will not correct on its own | Usually resolves within weeks to months |
| Treatment needed | Ponseti method (casting + bracing) | Usually none, or gentle stretching |
If you're unsure, a healthcare professional can quickly determine which type your baby has through a simple physical examination. For a detailed comparison, read our full guide on positional talipes vs clubfoot.
What Clubfoot Looks Like on Ultrasound
Many parents first learn about their baby's clubfoot during the 20-week anomaly ultrasound scan. On ultrasound, clubfoot appears as the foot being held in a fixed position perpendicular to the lower leg — essentially, the foot and shin form an L-shape rather than the foot hanging naturally.
ultrasound cannot determine the severity of clubfoot. A foot that looks dramatically affected on scan may turn out to be mild at birth, and vice versa. Ultrasound also cannot distinguish between true clubfoot and positional talipes with certainty, although experienced sonographers can often make a reasonable assessment.
If clubfoot is detected on ultrasound, you should be referred to a specialist team who can counsel you about the condition and begin planning for postnatal treatment. Understanding when clubfoot develops in pregnancy can also help provide context for the diagnosis.
What Does Bilateral Clubfoot Look Like?
Approximately 50% of clubfoot cases are bilateral, meaning both feet are affected. In bilateral clubfoot, both feet display the characteristic signs described above — turned inwards and downwards, with deep creases and smaller calves. The severity may differ between the two feet; it's common for one foot to be more affected than the other.
When both feet are affected, the appearance can be more striking because there is no "normal" foot for comparison. However, bilateral clubfoot responds just as well to the Ponseti method as unilateral clubfoot. Both feet are treated simultaneously, with casts applied to each foot at every weekly appointment.

How Clubfoot Changes During Treatment
One of the most reassuring aspects of the Ponseti method is that you can see the foot improving week by week during the casting phase. Here's what to expect:
Week 1-2: Correction of Forefoot Adduction
The first casts focus on correcting the inward curve of the forefoot. After the first one or two casts, you may notice that the C-shaped curve of the sole is starting to straighten.
Week 3-4: Correction of Varus
Subsequent casts address the inward turning of the heel. The foot begins to look more aligned, with the sole starting to face downwards rather than inwards.
Week 5-7: Correction of Equinus
The final casts, often combined with an Achilles tenotomy, correct the downward pointing of the foot. After this phase, the foot should be in a neutral or slightly overcorrected position.
Post-Treatment Appearance
After successful Ponseti treatment, the foot should look largely normal to the untrained eye. Some subtle differences may persist:
- The affected foot may be slightly smaller (usually 1-1.5 shoe sizes)
- The calf on the affected side may remain slightly thinner
- There may be minor differences in ankle flexibility
- The foot may have a slightly different shape compared to a non-clubfoot foot
These differences are typically cosmetic rather than functional and do not affect the child's ability to walk, run, or participate in sports and activities.
When to Seek Medical Advice
If you notice any of the following in your newborn's feet, contact your midwife, health visitor, or GP:
- One or both feet appear turned inwards and downwards
- The foot cannot be gently moved into a normal position
- There are deep creases on the sole of the foot
- One calf appears significantly smaller than the other
- The foot has a rigid, fixed position that doesn't change
Remember that clubfoot is not an emergency — it doesn't require immediate intervention in the delivery room. But early referral to a specialist clubfoot clinic ensures that treatment can begin within the first two weeks of life, which is the optimal window.

Frequently Asked Questions
Q: Can you tell how severe clubfoot is just by looking at it?
A: While experienced clinicians can make a reasonable assessment by visual inspection, formal severity scoring (such as the Pirani score) requires a hands-on examination. The visual appearance doesn't always correlate with the clinical severity — a foot that looks dramatically affected may actually be quite flexible and respond well to treatment, while a stiffer foot may look less obviously deformed.
Q: Does clubfoot look the same in every baby?
A: No, clubfoot varies significantly from baby to baby. Some babies have a mild form where the foot is only slightly turned, while others have a severe form where the sole faces almost completely upwards. The condition can also affect one foot (unilateral) or both feet (bilateral), and the severity may differ between the two feet in bilateral cases.
Q: Will my child's foot always look different?
A: After successful treatment with the Ponseti method, most children's feet look very close to normal. There may be subtle differences — a slightly smaller foot, a thinner calf — but these are rarely noticeable in everyday life. Most adults who were treated for clubfoot as babies report that people cannot tell which foot was affected.
Q: Can I tell from an ultrasound if my baby has mild or severe clubfoot?
A: No. Prenatal ultrasound can detect the presence of clubfoot but cannot reliably assess severity. The appearance on ultrasound doesn't correlate well with the clinical severity assessed after birth. This means you should try not to worry too much about how the foot looks on the scan — the full picture only becomes clear after your baby is born and examined by a specialist.
Q: My baby's foot looks turned in but I can gently straighten it — is this clubfoot?
A: If the foot can be gently moved to a normal position, it's more likely to be positional talipes rather than true clubfoot. Positional talipes is very common (affecting up to 1 in 100 babies) and usually resolves on its own without treatment. However, you should still have it checked by a healthcare professional to confirm. Read more about positional talipes vs clubfoot.
Q: Does the appearance of clubfoot get worse if left untreated?
A: Yes. Without treatment, the foot becomes more rigid over time as the bones harden and the soft tissues contract. In untreated clubfoot, adults may walk on the side or top of their foot, develop painful calluses, and experience significant disability. This is why early treatment is so important — the Ponseti method works best when started in the first few weeks of life.
