2-Stage PLS AFO for Children in Hamilton
Light, Flexible Support for Wobbly Feet and Ankles
The 2-Stage PLS AFO has a narrow, flexible strip up the back of the lower leg. PLS stands for posterior leaf spring, and that back section works a little like a spring: it lets the ankle move, then helps lift the foot again as your child steps.
At Foot Foundation in Hamilton, we assess first and choose the brace that gives your child the support they need without taking away movement they can still use.
What Is a 2-Stage PLS AFO?
Like all 2-Stage braces, it has two parts working together:
Stage one: a Surestep SMO that hugs the foot and controls how it rolls and twists.
Stage two: a taller shell up the lower leg with a flexible posterior leaf spring back.
The flexible back means the ankle can still bend as your child walks, while the brace helps stop the foot dropping and helps lift the toes clear of the ground.
Which Children Might It Help?
A 2-Stage PLS AFO may be considered for children who have:
low muscle tone (hypotonia) or high muscle tone (hypertonia)
difficulty keeping the ankle and knee steady when walking
moderate to severe wobble at the midfoot or ankle
trouble sensing where their feet and legs are (proprioception)
difficulty moving between positions, like standing up from the floor
moderate toe walking
legs that rotate in or out during walking
a foot that drops or catches when stepping, and would benefit from guided ankle movement

Comparing the Three 2-Stage AFOs
The solid option gives the most controlled ankle movement and is often considered for severe toe walking, crouch gait and significant instability. The PLS option has a flexible back that allows some movement, and is often considered for moderate toe walking, foot drop and rotation control.
The articulated option is hinged, so it bends at the ankle. It’s often considered for children who need the ankle to bend while walking.
What to Expect
Assessment: we check walking, muscle tone, ankle movement, strength and function.
Plan: we explain why a PLS suits, and what we expect it to change.
Casting or scanning: we capture your child's foot and leg shape, with careful attention to alignment.
Fitting: we check pressure points, strap comfort, shoe fit and walking in the brace.
Break-in: a gradual wearing plan, usually over two to three weeks.
Reviews: regular follow-up, shared with physio or your paediatrician where relevant.
Everyday Life With a PLS AFO
Shoes: a roomier, deeper shoe, often one to one and a half sizes bigger with a wide opening. Removable insoles help.
Socks: a long, thin, seam-free sock pulled smooth under the brace.
Putting it on: sock first, then the brace, then the shoe.
Skin checks: check after every wear at first. Mild redness fading within 20–30 minutes is normal. Lasting marks or blisters need adjusting.
Cleaning: wipe with a damp cloth and air dry away from heaters.
Growth: regular reviews keep the fit safe and the spring working properly.
Is a PLS AFO Right for My Child?
Other options may suit better if your child:
needs firmer ankle control → 2-Stage AFO Solid
needs a true hinge that bends freely → 2-Stage AFO Articulated
mainly needs foot support, not ankle control → Surestep SMO
mostly toe walks with a flexible ankle → Toe Walking SMO

Frequently Asked Questions
What does posterior leaf spring mean?
Posterior means at the back, and leaf spring describes the flexible strip that runs up the back of the calf. It bends as your child steps, then helps lift the foot.
How is it different from a solid AFO?
A solid AFO holds the ankle steady. A PLS allows some ankle movement while still guiding the foot, so it suits children who need less control.
Will my child trip less in it?
Often, yes. Because it helps lift the toes clear of the ground, many children catch their feet less often.
Can my child run in it?
Many children can. How much depends on their strength, balance and the reason for the brace, and we'll talk it through.
Does it need special shoes?
A roomier, deeper shoe is usually needed. We'll give you specific advice at the fitting.
Book an AFO Assessment in Hamilton
If your child toe walks, trips often or has weak or unsteady ankles, an assessment will show which level of support fits them best.
