W-Sitting in Children – How the Right Shoes Can Improve Posture and Gait
By Juan Valenzuela | Certified Children’s Shoe Fitter with 10+ Years of Experience | Last updated: June 2026
If you’ve noticed your child sitting with their knees bent inward and their feet splayed out to the sides — forming a shape that looks like the letter W from above — you’re not alone in wondering whether it’s something to be concerned about. W-sitting is extremely common in young children, and most parents are told not to worry. But as someone who has fitted shoes for hundreds of children with gait and posture issues, I can tell you that W-sitting is frequently a visible signal of an underlying condition that deserves attention — and that the right footwear can make a meaningful difference in how these children walk, stand, and develop.
What Is W-Sitting?
W-sitting occurs when a child sits on the floor with their bottom between their feet and their knees bent outward — one leg to each side — so the body and legs form a W shape when viewed from above. The hips are in a position of extreme internal rotation, and the thighs rotate inward while the lower legs splay outward.
Young children often gravitate toward this position because it provides a very wide, stable base of support. It requires less core and hip muscle engagement than other floor-sitting positions — which is exactly why it can be a red flag. Children who default to W-sitting are often doing so because they don’t have sufficient muscle strength or joint stability to maintain other positions comfortably.
Why Do Some Children W-Sit More Than Others?
W-sitting is common across all children to some degree — most children try it at some point. But children who consistently prefer W-sitting over other positions, or who return to it whenever they are floor-sitting, often have one or more of the following underlying conditions:
Low muscle tone. Children with low muscle tone have less tension in their muscles at rest. Their bodies require a wider, more stable base to sit upright — and W-sitting provides that base with less muscular effort. Frequent falls, delayed motor milestones, and a generally “floppy” appearance are associated signs. For a dedicated guide, see Best Shoes for Kids with Low Muscle Tone.
Hypermobility. Children with hypermobile joints have ligaments that are more lax than normal. Their hips can achieve the extreme internal rotation that W-sitting requires more easily than typical children, and the position offers the joint stability that their loose ligaments cannot. W-sitting, flat feet, frequent ankle sprains, and complaints of leg pain often appear together in hypermobile children. See Best Shoes for Kids with Hypermobility.
In-toeing (pigeon toe). Children with femoral anteversion — an inward rotation of the thigh bone — naturally find W-sitting comfortable because the position aligns with their femur’s rotational position. The same inward rotation that makes W-sitting feel natural is what makes their feet point inward when they walk. See Pigeon Toe Treatment for Kids.
Hip muscle tightness. Tight hip flexors, adductors, or internal rotators can pull children into W-sitting posture involuntarily. These children often show limited range of motion when you try to move their legs into other positions.
General developmental stage. In children under three, W-sitting is so common as to be developmentally unremarkable. The concern grows when the preference persists past age three to four, particularly if associated with any of the conditions above.
What Prolonged W-Sitting Can Cause
The concern with W-sitting isn’t occasional use — it’s habitual, prolonged use as the primary floor-sitting position. When a child spends hours each day with their hips in extreme internal rotation:
- Hip and knee joint stress accumulates from the sustained abnormal loading pattern
- Muscle tightness in the hip internal rotators develops over time, reinforcing the inward rotation tendency
- Core and hip strength may fail to develop appropriately because W-sitting bypasses the muscle activation that other sitting positions require
- In-toeing gait can worsen as the hip muscles adapt to the rotated position
- Balance and coordination may be compromised as the child’s movement patterns develop around the W-sitting posture
The five adult testimonials below reflect the real range of outcomes — some adults who W-sat habitually as children have significant hip and knee problems; others have none. The individual variability is real. But the consistent clinical advice from physical therapists is that habitual W-sitting should be actively discouraged — the downside risk of intervention is low, and the potential benefit of redirection is meaningful.
Real Stories from Adults Who W-Sat as Children
The following experiences — shared by adults reflecting on their own childhoods — illustrate both the potential consequences and the variability of outcomes from prolonged W-sitting.
“My husband spent most of his childhood sitting in the W position, and now, in his forties, he’s had both hips replaced. He walks with his feet turned inward and relies on orthotics every day.”
“I struggled with low muscle tone and W-sat throughout my childhood and even into adulthood. Now at 40, I constantly battle hip and knee pain. When my daughter was diagnosed with low muscle tone, I made sure to discourage her from W-sitting.”
“I’m in my thirties and still recovering from years of W-sitting as a child. I deal with in-toeing and, as I get older, knee, hip, and foot pain. I wish someone had stepped in to help me earlier. Today, I depend on special shoes with orthotics to manage the discomfort.”
“Even though I’m 35 and sat in the W position all the time — and honestly still do — I’ve never experienced any hip or knee issues.”
“I’ve been W-sitting for over 50 years and maintain perfect posture with no foot, leg, or back pain to show for it.”
These stories aren’t meant to alarm parents — they’re meant to illustrate why physical therapists recommend discouraging the habit rather than waiting. The cost of redirecting the behavior early is minimal. The cost of not acting in the cases where it does cause long-term issues is high.
How to Redirect W-Sitting
The most effective approach is consistent, positive redirection rather than correction. When you see your child W-sitting, gently encourage them to shift to one of the following positions instead:
Long sitting — legs stretched straight out in front. Requires active hip and hamstring flexibility.
Side sitting — both legs bent to the same side. A transitional position that’s easy for most children.
Criss-cross sitting — legs folded in front, like traditional cross-legged sitting. Requires more core and hip engagement than W-sitting.
Sitting on a low stool or bench — eliminates floor-sitting entirely for activities where it’s practical.
Consistency and positive reinforcement work better than constant correction. The goal is to make other positions feel natural over time, not to make the child feel self-conscious. Working with a physical therapist can accelerate this process, particularly for children with low muscle tone or hypermobility.
How Can Shoes Help?
Shoes won’t stop a child from W-sitting — that requires behavioral redirection and, in some cases, physical therapy. But the right shoes address the underlying foot and gait conditions that often accompany W-sitting and that W-sitting can worsen. Specifically:
For children with in-toeing: A straight-last shoe with a firm heel counter guides the foot toward a more forward-pointing position during walking, reducing the inward rotation pattern that W-sitting reinforces.
For children with flat feet or overpronation: A supportive shoe with a dense midsole and firm heel counter lifts and stabilizes the arch, reducing the ankle rolling and gait inefficiency that often co-occur with W-sitting habits.
For children with low muscle tone or hypermobility: A structured shoe with a firm heel counter and stable outsole provides the external stabilization that the child’s own muscles and ligaments are struggling to generate. The shoe does the stabilizing work that the body can’t yet do on its own.
The improvement in walking posture from the right shoes is often visible immediately. And better walking mechanics reduce the compensatory patterns — including W-sitting — that children adopt when their feet and legs aren’t functioning efficiently.
What to Look for in a Shoe for a Child Who W-Sits
The shoe features that matter most for children who W-sit are the same ones that address the underlying conditions — in-toeing, flat feet, low muscle tone, and hypermobility:
Firm heel counter. The most important structural feature. Holds the heel upright and reduces inward ankle rolling.
Straight last. Guides the foot toward a more neutral, forward-pointing position during walking — directly counteracting the inward rotation associated with W-sitting and in-toeing.
Stable base of support. A wide, dense outsole resists torsional forces and provides the stable platform that children with low muscle tone and hypermobility need.

The Role of Physical Therapy
If your child W-sits habitually — particularly if they also show signs of in-toeing, flat feet, low muscle tone, or hypermobility — a physical therapy evaluation is worth requesting. A physical therapist can:
- Assess your child’s hip range of motion, muscle strength, and joint stability
- Determine whether the W-sitting is a habit or a compensatory mechanism for an underlying condition
- Provide targeted exercises to develop the hip and core strength that makes other sitting positions comfortable
- Advise on whether orthotics are indicated alongside supportive footwear
- Work with you on a practical redirection strategy for home
Shoes and physical therapy work together — the shoe provides structural support during walking; the physical therapist builds the muscular strength that eventually reduces reliance on that support.

Frequently Asked Questions
At age two, W-sitting is developmentally very common and usually not a cause for concern on its own. The time to take action is if it persists as the strongly preferred position past age three to four, particularly if accompanied by in-toeing, frequent falls, flat feet, or delayed motor milestones. If those signs are present, a physical therapy evaluation is worthwhile regardless of age.
Some do, some don’t. Children whose W-sitting is purely a positional habit often transition to other sitting styles naturally as they develop. Children whose W-sitting compensates for an underlying condition — low muscle tone, hypermobility, or femoral anteversion — are much less likely to stop spontaneously, because the underlying cause that makes W-sitting comfortable hasn’t changed.
The New Balance 990v6 is my top recommendation for children whose physical therapist has specifically requested supportive footwear. If your child also wears orthotics, ensure the shoe you choose is deep enough to accommodate them — the 990v6 is the only shoe on this list that can fit AFOs and SMOs in addition to standard insoles.
The honest answer is: it depends on the individual, the underlying condition, and how long and consistently the habit persists. The adult testimonials in this article reflect the real range — some people W-sat for decades with no consequences; others have significant hip and joint problems. Because there’s no reliable way to predict which outcome a given child will have, the precautionary approach — discouraging the habit and addressing underlying conditions with proper footwear — is always the better choice.
Very likely, yes. Both habitual W-sitting and in-toeing are frequently caused by femoral anteversion — the inward rotation of the thigh bone. The same hip orientation that makes W-sitting feel natural causes the feet to point inward during walking. Addressing one often requires addressing the other. See Pigeon Toe Treatment for Kids for the full guide on in-toeing and footwear.
