GUARANTEE
60-day money-back guarantee
Try GrowStep risk-free. If your child doesn't feel more comfortable and supported, we'll give you your money back.
What size should I choose?
Pick your child's usual shoe size — tap Size chart above for US, UK and EU sizes. In between sizes? Go one size up and trim the toe end with scissors for a snug fit.
Will they fit any shoes?
Yes — sneakers, cleats, school shoes and boots. Any shoe with a removable insole works: take the original insole out and slide GrowStep in.
Can they ease my kid's pain?
GrowStep supports the arch and cushions the heel, which takes pressure off the heels, knees and lower back during sport and growth spurts. They're a comfort and support insole, not a medical treatment — if pain is severe or doesn't improve, check in with your child's doctor.

Less pain. More play.
Sore arches, aching heels, knees that hurt after practice — no kid should have to push through that. GrowStep insoles are made for growing kids and teens with flat feet, overpronation and heel pain from sport and growth spurts. Arch support, a cushioned heel and gentle alignment take pressure off their joints and guide each step into a better position — so they can get back to growing, running and feeling good.
Built for kids who never sit still
The GrowStep difference
1234Overpronation control
Helps guide feet that roll inward back into line, easing strain on the heels, knees and lower back.
Cloud-soft heel
A thick, shock-absorbing heel softens every landing at school, practice and play.
Massaging comfort zones
Raised nodules under the forefoot gently stimulate the sole to ease tired, achy feet.
All-day support
Made for kids who are on their feet from the first school bell to the final whistle.
Support while they're still growing
Between about 8 and 15, bones often grow faster than the muscles and tendons around them. That's when flat feet and inward rolling put extra load on the heels and knees. GrowStep gives the arch and heel steady support through those growth spurts, so every step lands better aligned.
Slide them in, trim to size if needed, and they're ready for school, sport and weekends.
Small insole. Big difference.
Thick bubble foam absorbs impact, so growing joints take less of a pounding.
From Kids 3 up to Men's 15 — the whole family can wear them.
If your child doesn't feel the difference, you get your money back.

Frequently asked questions
Who are GrowStep insoles for?
Growing kids and teens — and adults — dealing with flat feet, inward rolling (overpronation), heel pain, or sore feet and knees from sport and long days on their feet.
What makes them different from regular insoles?
Most insoles are just a flat layer of cushioning. GrowStep combines arch support, a thick cloud-foam heel and massaging comfort zones in one slim insole that fits everyday and sports shoes.
What size should I buy, and how do I clean them?
Order your child's usual shoe size (see the size chart). Between sizes? Size up and trim the toe end. To clean, hand-wash with mild soap and cool water, then let them air-dry.
How long do they last?
They're made for daily wear. Most families replace them when their child moves up a shoe size — which is why a lot of parents pick a bundle.
Are they a medical treatment?
No. GrowStep is a comfort and support insole, not a medical device. If your child's pain is severe, sudden or doesn't get better, please see their doctor or a podiatrist.
What kind of discomfort can they help with?
Arch and heel discomfort, tired feet, and the knee and lower-back strain that can come from flat feet or feet that roll inward.
Do they work for flat feet or high arches?
Yes. The contoured arch supports flat and low arches, and the soft foam stays comfortable for higher arches too.
Do you offer a guarantee?
Yes — every order is covered by our 60-day money-back guarantee.
