When Is It Time to Replace My Child’s AFOs or SMOs?
Ankle-Foot Orthoses (AFOs) and Supramalleolar Orthoses (SMOs) play an important role in helping children walk, balance, and grow with confidence. But just like shoes or clothes, orthotics don’t last forever. Over time, they can become too small, worn out, or less effective. Knowing when it’s time to replace your child’s AFOs or SMOs is key to making sure they continue to get the support they need.
1. Growth Spurts
Children grow quickly, and orthotics that once fit perfectly can become too tight or short.
Signs your child may have outgrown their orthotics:
Red marks, blisters, or pressure spots on the skin
Complaints that the brace feels tight or hurts
Toes hanging over the edge of the footplate
Trouble putting the orthotic on or taking it off
2. Changes in Walking or Posture
If your child’s walking has become uneven again or they’ve started toe-walking or tripping more often, their orthotics may no longer be doing their job.
Look for:
Limping or favoring one side
Increased falls or loss of balance
Returning to an old gait pattern the orthotics previously helped improve
3. Visible Wear and Tear
Just like shoes, orthotics wear down with use. Cracks or worn-out padding can reduce their effectiveness.
Check for:
Cracked or broken plastic
Loose or worn straps and buckles
Flattened or torn padding
Unusual noises (like squeaking or clicking) when your child walks
4. Changing Needs
Sometimes, a child’s mobility or strength improves—or they develop new challenges—which may require a different type or style of orthotic.
Consider an update if:
Your child’s physical therapist or orthotist recommends a new design
Your child is ready to transition to a less supportive brace
They’ve had a recent growth or developmental evaluation
5. Time Since Last Replacement
Even if everything seems fine, it's still a good idea to have orthotics checked regularly.
General guideline:
Orthotics typically last 6 to 12 months for growing children
Regular check-ins (every 3-6 months) with your orthotist can help catch issues early
Final Thoughts
Replacing your child’s AFOs or SMOs at the right time ensures they stay comfortable, safe, and supported as they grow. If you’re noticing signs that it might be time for a new pair, or if it’s been a while since your child’s last fitting, it’s a great idea to schedule a check-up.
