The foot points in, and the foot is not the problem

A parent sees a toe pointing inward and reasonably assumes the correction is slipping. Sometimes it is. Often the foot is perfectly well corrected and the whole lower leg is rotated slightly inward instead, which looks identical from above and means something completely different. Tell it what you are actually seeing.

Written by Heath, who has lived it: casts from birth, a fusion at sixteen, the US Army, and distance running.

What are you actually looking at?

Pick everything you can see. Look at your child standing, from in front and from behind, on a hard floor, when they are not performing for you.

What you see

Internal tibial torsion

The shin bone itself is twisted slightly inward along its length, so a perfectly corrected foot still points inward because the whole leg below the knee is rotated. The giveaway is the kneecap: if it faces straight forward while the foot turns in, the rotation is in the bone between them.

Extremely common in young children generally, and more common again after clubfoot. It usually improves on its own as a child grows.

Most common

Residual forefoot adductus

The front half of the foot curves inward while the heel sits correctly underneath the leg. Looked at from the sole, the outer border is curved, not straight. This is the commonest bit of clubfoot to remain incompletely corrected, and mild versions are frequently left alone because they cause no functional problem.

A remainder instead of a return, and it does not progress the way a relapse does.

A remainder

Relapse of the hindfoot

The heel itself tilts inward when the child stands, and the ankle may have lost some upward movement. This is the one that matters most, because it is the correction genuinely losing ground, not a rotational variant. It tends to appear or worsen over months instead of being longstanding.

Heel position is the single most important thing to look at, and it is what separates a cosmetic pattern from a clinical one.

Act on this

Fatigue and habit

Plenty of children turn their feet inward when tired, when concentrating on something else, or when running fast, and stand perfectly straight otherwise. If it comes and goes with energy levels instead of being present on every step, it is describing muscle tiredness rather than structure.

Watch on a good morning and at the end of a long day. A pattern that changes is rarely structural.

Watch, do not act

Femoral anteversion, higher up

Rotation originating at the hip and not the shin, which turns the whole leg inward including the kneecap. The classic sign is a child who sits comfortably in a W shape and whose kneecaps point inward when standing. Unrelated to clubfoot, common in young children, and usually resolves with growth.

Worth distinguishing because it is the one explanation that has nothing to do with the foot at all.

From the hip

Time to be seen, whatever it is

Any in-turning that has clearly increased over a few months, any loss of upward ankle movement, any new limp, or any activity your child has quietly given up. The distinction between torsion and relapse is made by examination, and it matters because one needs nothing and the other needs treating promptly.

Photographs from behind, dated, are the most useful thing you can bring to that appointment.

Get it checked

Why torsion and clubfoot travel together

Internal tibial torsion is common in all young children and appears more often alongside clubfoot (club foot). The likely reasons overlap: the same developmental positioning that contributes to a clubfoot also affects how the lower leg bones rotate, and the affected leg then grows and remodels in a slightly different pattern.

Bones remodel in response to load through childhood1, and rotational profiles typically improve as children grow into their teens. That is why watchful waiting is the standard approach for torsion and why surgery to correct rotation is uncommon and reserved for significant, persistent cases that cause functional problems.

TorsionA rotational profile of the bone. Usually improves with growth. Rarely needs anything.

AdductusResidual curve of the forefoot. A remainder instead of a return, often left alone.

RelapseThe heel tilting inward and motion reducing. Progressive, and needs treating promptly.

Look at the heel from behind. Almost every version of this question is answered there.

What the evidence says about intervening

Special shoes, twister cables, night splints aimed at rotation and corrective footwear for in-toeing have all been studied and none has been shown to change rotational alignment. Rotational profiles improve because children grow, not because of what is on their feet.

That is genuinely liberating for a family already managing a bracing schedule. The brace prescribed for your child’s clubfoot is doing a specific job and should absolutely be worn as directed. Additional footwear bought to fix in-toeing is a cost with no evidence behind it.

Torsion in clubfoot

Does tibial torsion cause problems in adulthood?

It can, and the complaint is the knee rather than the foot. Torsion persists into adulthood, and the review written for adult orthopedic surgeons calls it a recognized cause of patellofemoral pain and instability that is commonly overlooked in adults. Most rotation never causes a symptom, so this is a thing to know about rather than to expect. The adult version covers how it is measured without a scan and where the surgical threshold sits.

What is tibial torsion in clubfoot?

A slight inward twist along the length of the shin bone, so a well-corrected foot still points inward because the whole leg below the knee is rotated. The giveaway is a kneecap facing forward while the foot turns in.

How do I tell torsion from relapse?

Look at the heel from behind while your child stands. Torsion leaves the heel sitting correctly under the leg; relapse tilts it inward and usually reduces upward ankle movement as well. Speed matters too, relapse develops over months.

Does in-toeing need treating?

Rotational in-toeing usually does not, because it improves as children grow. What needs treating is relapse, which is a different finding, and the distinction is made by examination, not by appearance from above.

Do corrective shoes help in-toeing?

No. Special shoes, twister cables and rotational splints have been studied and none changes rotational alignment. Improvement comes from growth. The clubfoot brace your child was prescribed is a different thing doing a different job.

Will it affect running or sport?

Mild rotational differences generally do not, and plenty of children with in-toeing run perfectly well. Persistent significant torsion that causes tripping or functional difficulty is worth assessing, and it is uncommon.

When should I take this to the clinic?

If the in-turning has clearly increased over a few months, if upward ankle movement has reduced, if there is a new limp, or if your child has quietly dropped an activity. Bring dated photographs of both heels from behind.
