Why Do I Walk With My Feet Turned Out?
Out-toeing in adults, sometimes called duck feet walking, happens when one or both feet point outward instead of straight ahead. It is usually caused by the way your hip or shin bones are shaped, or by tightness and weakness around the hip. A whole-body standing scan can show the exact rotational profile of your legs so the right approach is chosen.
Key takeaways
- Out-toeing is a rotational pattern, not just a foot problem. The cause often sits at the hip or shin.
- Common structural causes include femoral retroversion and external tibial torsion.
- Lying-down scans relax the legs, hiding how rotation really loads the joints when you stand and walk.
- A standing EOS scan maps the full rotational profile from hip to ankle in one low-dose image.
- Understanding the cause helps clinicians decide whether physiotherapy, orthotics or further investigation is needed.
What is out-toeing in adults?
Out-toeing is the medical term for a gait pattern where one or both feet point outward as you walk, rather than facing forwards. You might recognise it as "duck feet." In children it often resolves on its own, but in adults it tends to be a fixed pattern linked to your bone structure, joint range of motion, or long-standing muscle imbalances.
The direction your foot points during walking is called the foot progression angle. When that angle is noticeably outward, the rotation has to come from somewhere up the chain. It might start at the hip socket, the thigh bone, the shin bone, or the foot itself. Often it is a combination of more than one level.
How do you know if you have out-toeing?
You may have noticed it yourself, or someone else may have pointed it out. Here are the most common signs.
When you stand or walk, your feet visibly point outward rather than straight ahead.
The inner edges of your soles wear down faster because of the rotated foot position.
Pain or fatigue in the hip, knee or ankle after walking or standing for a while, caused by compensatory loading.
Legs flick outward when you run, reducing efficiency and sometimes causing tripping.
What causes out-toeing in adults?
Out-toeing is usually structural, meaning the bones themselves are shaped in a way that rotates the leg outward. Sometimes soft tissue tightness or joint changes play a role too. Below are the most common causes.
The thigh bone is twisted so the hip naturally sits in more external rotation. This is one of the most common structural causes. Learn more about anteversion versus retroversion.
The shin bone is rotated outward relative to the thigh bone, pointing the foot outward even when the hip is neutral.
Tight external rotator muscles or a stiff hip capsule can limit internal rotation, forcing the leg outward. Read about hip anteversion and retroversion.
Collapsed arches can cause the foot to roll inward and splay outward, adding to the out-toed appearance.
In many cases, more than one factor is present. For instance, mild femoral retroversion combined with external tibial torsion can produce a noticeable external rotation gait even though neither factor alone would be remarkable. This is why a full rotational profile, measured from hip to ankle, gives a much clearer picture than looking at one joint in isolation.
How is out-toeing assessed with standing imaging?
A standing, weight-bearing scan captures your skeleton the way it actually works, under gravity, with your muscles engaged. When you lie down for a conventional X-ray, CT or MRI, your muscles relax and your joints settle into a different position. Rotational patterns that are obvious when you walk can effectively disappear on a lying-down image.
An EOS scan at ScanAlign, 3D standing skeletal imaging, captures your full legs in one upright exposure. Because you are standing naturally, the image shows the true rotational alignment of each bone segment, from the hip socket down to the ankle. A 3D reconstruction can then map the precise twist of the femur and tibia, giving clinicians a complete rotational profile to guide decisions.
The scan uses about 90% less radiation than a standard X-ray, around ten times less.
Standard X-rays, CT and MRI are taken lying down. Without gravity and muscle engagement, rotation at the hip, knee and ankle can be masked. CT can measure bone twist using special slices, but it delivers a higher radiation dose and still does not show how the body loads in a standing position.
Your body is a connected chain. If the femur sits in extra external rotation, the knee, shin and foot all have to compensate. Pain often shows up away from the root cause. A gait analysis combined with a standing rotational scan gives both the dynamic movement picture and the structural explanation behind it.
When is MRI better? EOS excels at showing bone alignment, joint spacing and rotational geometry. If your clinician suspects soft-tissue damage, a labral tear, cartilage injury or nerve involvement, MRI is usually the better tool. The two investigations complement each other.
What helps with out-toeing once you know the cause?
The right approach depends entirely on what is driving the rotation. That is why accurate imaging matters before any plan is made. ScanAlign is a diagnostic imaging clinic, so it does not provide treatment, but the information from a standing scan helps your clinician choose the best path.
- Physiotherapy and strengthening. If the out-toeing is partly driven by muscle tightness or weakness, a targeted programme can improve hip internal rotation range and gait mechanics.
- Orthotics or footwear changes. When flat feet contribute, custom insoles may help control the foot's position and reduce compensatory rotation further up the chain.
- Monitoring. If imaging shows a mild structural variant with no pain or functional limitation, the best course may simply be reassurance and periodic review.
- Surgical referral. In rare cases where significant femoral retroversion or tibial torsion causes persistent pain or instability, an orthopaedic surgeon may discuss corrective options. Detailed rotational measurements from a standing scan are essential for planning.

Yes. "Duck feet" is a common everyday term for out-toeing, where one or both feet point outward during standing and walking. The medical term describes the same pattern.
Femoral retroversion is a structural twist of the thigh bone that positions the hip in more external rotation than average. It is one of the most common skeletal causes of out-toeing in adults.
It can. When the leg rotates outward, the knee and hip joints are loaded differently. Over time this altered loading may contribute to pain, cartilage wear or compensatory muscle fatigue in those areas.
If the cause is mainly muscle tightness or weakness, targeted physiotherapy can improve symptoms and gait mechanics. If the cause is bony, such as femoral retroversion or tibial torsion, exercises cannot change bone shape but may help manage symptoms.
Rotation is best seen under load. When you lie down, your muscles relax and joints settle, which can mask the rotational pattern. A standing scan shows how your bones are actually aligned when gravity, muscle activity and weight bearing are at play.
Yes. EOS uses about 90% less radiation than a standard X-ray, around ten times less. It is a very low-dose imaging method. You can find more detail on our book a rotation and alignment scan page.
No. ScanAlign accepts self-referrals. You can book directly without needing a letter from your GP.
They can contribute. Collapsed arches may cause the foot to roll inward and splay outward, making the out-toed appearance more pronounced. A full-leg standing image helps separate the foot component from rotation higher up in the leg.
Asymmetrical out-toeing is worth investigating because it suggests a side-to-side difference in bone shape, hip range or muscle balance. One-sided patterns often cause compensatory changes in the pelvis, spine or opposite leg.
Pricing details are available on our website. You can check current information on the book a rotation and alignment scan page.
