In-toeing, commonly called “pigeon-toeing,” is when the feet point inward instead of straight ahead during standing or walking. It is one of the most frequent reasons parents bring a child to an orthopedic specialist, and in the vast majority of cases it resolves on its own as the child grows. The inward rotation can originate from three different spots in the leg: the foot, the shinbone, or the thighbone.
The Three Causes of In-Toeing
Each cause tends to show up at a different age, which is one of the first things a doctor will consider when evaluating a child.
Metatarsus Adductus (the Foot)
This is a curve in the foot itself, present at birth, where the front half of the foot angles inward and gives the foot a C-shape. Babies with metatarsus adductus often have a noticeably high arch and a wide gap between the big toe and the second toe. Doctors classify the foot as “flexible” if they can gently straighten the forefoot by hand, or “non-flexible” if it resists correction. Flexible cases typically improve without treatment during the first year of life. Non-flexible feet may need serial casting, where a series of casts gradually coax the foot into a straighter position, similar to how clubfoot is treated.
Internal Tibial Torsion (the Shinbone)
This is the most common cause of in-toeing in toddlers between ages 1 and 3. The shinbone (tibia) is rotated inward more than usual, so even though the knee points forward, the foot angles in. It often affects both legs. On a physical exam, the doctor measures what’s called the thigh-foot angle: with the child lying face down and the knee bent, they look at how the foot lines up relative to the thigh. More than 10 degrees of inward rotation is considered in-toeing range.
Most children with tibial torsion outgrow it by age 5, and nearly all do by age 6. The bone gradually untwists as the child walks, runs, and grows.
Femoral Anteversion (the Thighbone)
When the thighbone (femur) is rotated inward at the hip, the entire leg, including the knee, turns in. This is the cause parents typically notice between ages 3 and 6. Children with femoral anteversion can rotate their hips inward much farther than outward, and they often prefer sitting in the “W” position, with their knees bent in front and their feet splayed out to the sides. A study of over 1,100 children found that 75% of in-toeing cases were linked to femoral anteversion, and W-sitting was significantly associated with in-toeing gait.
All children are born with a degree of femoral anteversion. It decreases naturally throughout childhood and usually reaches adult levels around age 10. The W-sitting preference is a consequence of the extra inward rotation, not a cause of it. Children sit that way because it’s more comfortable for their anatomy.
How In-Toeing Is Diagnosed
Diagnosis is almost entirely based on a physical exam. The doctor watches the child walk, checks the range of rotation at the hips, measures the alignment of the shinbone, and examines the shape of the foot. X-rays and imaging are rarely needed unless the foot is non-flexible or something unusual is going on, like pain on one side only.
For tibial torsion specifically, the thigh-foot angle is the key measurement. In infants, the average is about 5 degrees inward, with a wide normal range. By age 8, the average shifts to about 10 degrees outward. A reading beyond 10 degrees inward in a walking child points toward internal tibial torsion as the cause of in-toeing.
Does In-Toeing Need Treatment?
For most children, no active treatment is needed. The three common causes of in-toeing are considered normal rotational variations, and the vast majority resolve with growth. Special shoes, shoe inserts, and braces have been studied repeatedly, and evidence for their effectiveness in typical, otherwise healthy children is limited. Current orthopedic guidelines generally do not recommend corrective footwear for routine in-toeing.
Orthotics do have a role in specific situations. Children with neuromuscular conditions who also have rotational gait problems may benefit from compression garments, rotational bracing systems, or foot orthotics, depending on severity. But for a neurologically typical child whose feet turn in, the standard approach is reassurance and monitoring over time.
The one form of in-toeing that sometimes requires early intervention is non-flexible metatarsus adductus. Because the foot bones are still soft in infancy, serial casting in the first several months of life can be very effective at correcting the curve before the bones harden.
When Surgery Is Considered
Surgery for in-toeing is rare and reserved for children older than 8 whose rotation has not corrected on its own and who have ongoing symptoms like hip or knee pain, or frequent falls that interfere with daily activities. Before surgery is discussed, extensive physical therapy is tried first. Children younger than 8 are observed rather than operated on, because spontaneous correction is still expected. Asymptomatic femoral anteversion, no matter how pronounced, is not treated surgically.
Signs That Warrant a Closer Look
Most in-toeing is painless and symmetrical, affecting both legs equally. The American Academy of Orthopaedic Surgeons recommends evaluation by a specialist if in-toeing is accompanied by pain, swelling, or a limp. Asymmetry, where one leg turns in significantly more than the other, also deserves attention, as it could point to something other than a routine rotational variation. A child who trips frequently enough to limit participation in activities, or whose gait worsens rather than improves after age 5 or 6, is also a reasonable candidate for a specialist visit.
