Orthopedic Features Explained
High Built-In Arch Support
Structured medial arch support built into the footbed encourages healthy foot alignment and helps reduce excessive inward rolling (overpronation).
Extended Ankle Support
A higher-cut collar wraps around the ankle joint for added lateral stability – helpful for early walkers, hypermobility, and unsteady gait.
Shock-Absorbent Thermoplastic Outsole
Lightweight, slip-resistant sole that cushions impact at heel strike while flexing naturally at the forefoot.
Anti-Bacterial Insole
Breathable leather lining treated to keep the inside of the shoe fresh, dry, and hygienic during all-day wear.
Adjustable Velcro Fastening
Hook-and-loop straps allow quick, independent fastening and fine-tuned volume adjustment across narrow or high-instep feet.

What support does this shoe give?
The features listed on this shoe are the ones it includes – such as a dense heel counter, high built-in arch support, a Thomas heel, or extended ankle support. Pediatric orthopedists, physical therapists, and podiatrists recommend our range for children who need structured support, who wear orthotics, or who are learning to walk.
How do I choose the right size?
Measure your child’s feet in centimeters, then use our EU size chart.
- Stand them barefoot on a sheet of paper (for babies, measure while lying down). Mark the back of the heel and the longest toe.
- Measure between the marks in centimeters. Avoid adding extra length unless specifically recommended.
- Match that length on the chart. If the feet differ, size by the larger foot.
- Between sizes, size up.
Wearing an orthotic, AFO, or SMO? Measure the foot with the device on.
If you’re unsure, email the foot length in centimeters and the model to support@firstwalkers.com. We cover return shipping for one return per customer per 12 months if the fit isn’t quite right. Full steps are in our measuring guide.
Will an orthotic, AFO, or SMO fit in this shoe?
Only when the features on this shoe include orthotic-compatible, an extended tongue, or a removable insole. If they don’t, look at our high-cut boots and sneakers with laces or multi-strap Velcro openings.
Measure the foot with the device on, then check the size chart. Email us the orthotic’s brand, model, and length at support@firstwalkers.com if you want help choosing.
Are they easy to put on?
The fastening is named in this shoe’s features: Velcro, buckles, laces, a side zipper, or a combination. Velcro is the simplest when that is the fastening listed. A lace, zip, or buckle needs to stay done up for the support that style is built to give.
What if the size is wrong?
You have 14 days from delivery to return unworn shoes in their original packaging for a refund or exchange. First Walkers EU covers return shipping for up to one return per customer per 12 months. Email support@firstwalkers.com with your order number and we’ll send the return steps.
