Do these sandals really work as well as orthotic shoe inserts?

The Arch-Up sandal uses the exact same biomechanical arch shape found in our best-selling Footlogics Kids insoles — the ones prescribed by paediatricians across Australia, the US, and the UK. The footbed features a 15mm high arch support, a deep heel cup, and metatarsal raise — the three core elements of any quality orthotic. While a custom-moulded orthotic will always be the gold standard, the Arch-Up delivers clinically meaningful support in a sandal format that children actually want to wear. For the vast majority of children with flat feet or low arches, Arch-Up provides excellent everyday support throughout the summer months.

How do I know the sandals will fit when I buy online?

We’ve made this as simple as possible. Our size chart maps US children’s shoe sizes to exact foot lengths in inches, from US 11C right through to US 3Y. The most accurate method is to have your child stand on paper, mark the heel and big toe, measure the distance, and cross-reference with the chart. If your child is between sizes, always choose the larger size for the best fit and room to grow. And remember — if the size isn’t right, our 30-day money-back guarantee means returns are completely hassle-free.

How does the 30-day risk-free trial work?

Simple. Order your Arch-Up sandals and let your child wear them for up to 30 days. If for any reason you’re not completely satisfied — wrong size, not the right fit for your child, or you simply change your mind — contact us within 30 days of purchase and we’ll arrange a full refund, no questions asked. We’re confident in our product, and we want you to be too. There’s genuinely nothing to lose.

My child already wears orthotics in winter shoes. Can they wear Arch-Up in summer too?

Absolutely — and this is exactly what the Arch-Up was designed for. Many parents face the frustrating reality that their child gets excellent arch support during winter via orthotic insoles, but the moment sandal season hits, that support vanishes entirely. The Arch-Up bridges that gap, delivering the same biomechanical support in an open-toe sandal format. Your child can enjoy the freedom of summer footwear without giving up the foot support they need.

Are the sandals suitable for a child who doesn't yet have a diagnosed foot condition?

Yes. Even if your child hasn’t been diagnosed with flat feet, the Arch-Up supports healthy development during the critical years when the arch is actively forming (ages 3–8). Studies suggest up to 70% of young children have flat feet — and many go undiagnosed. Preventive arch support during this period can help promote healthier foot development, better posture, and greater comfort during active play. Think of it as the most proactive thing you can do for your child’s long-term foot health.

The Sandal That Actually Supports Growing Feet

Up to 70% of children aged 3–6 have flat feet. Most summer sandals offer zero arch support — leaving little feet vulnerable all season long. Not anymore.

The problem

Is your child’s summer footwear failing them?

Between ages 4 and 8, children's arches are actively forming. During winter, orthotic insoles provide critical support inside shoes — but the moment sandal season arrives, that support disappears entirely.

44–70%

of children aged 3–6 have flat feet

Age 6–7

when arch development should be complete

Children with flat feet or low arches may experience:

Foot fatigue and tired legs after play
Heel pain, especially in the morning
Excessive pronation (ankles rolling inward)
Reduced endurance and reluctance to walk

⚠️ Flat feet in children are extremely common — and often go unsupported in summer footwear

What's inside

8 biomechanical features. One sandal.

Every detail of the Arch-Up is engineered to support healthy foot development — not just comfort.

Feature 01

Biomechanical Arch Support

A 15mm anatomically contoured arch prevents excess pronation and maintains natural alignment of the foot, ankle, and lower leg during walking and running.

Feature 02

Deep Stabilising Heel Cup

Cradles and stabilises the heel in a neutral position, reducing excessive heel movement and improving posture, balance, and foot control during active play.

Feature 03

Metatarsal Support

Distributes body weight and impact across the entire foot, reducing fatigue and pressure on the ball of the foot during long days of walking and exploring.

Feature 04

Cushioning EVA Footbed

Lightweight shock-absorbing EVA reduces impact on developing joints — feet, knees, and hips — so children can stay active longer without fatigue.

Feature 05

Proprioceptive Bubble Surface

Raised cushioning nodes stimulate the sole of the foot, enhancing sensory feedback, encouraging natural muscle engagement, and promoting better balance and coordination.

Feature 06

10mm Heel-to-Toe Drop

A gentle gradient promotes a more natural walking motion and reduces strain on the Achilles tendon — especially beneficial for children with flat feet or over-pronation.

Feature 07

Flexible EVA Midsole

Lightweight and flexible enough to allow natural foot movement during running and climbing, without feeling bulky or restrictive during active play.

Feature 08

TPR Anti-Slip Traction Pads

Durable rubber pads on the outsole provide reliable grip on wet and dry surfaces, reducing the risk of slips and falls during outdoor adventures.

35°

of real arch support

The same biomechanical angle found in custom orthotic insoles

Inside the 'Arch-Up 'footbed

The contoured footbed is where the real magic happens. Each element works together to guide the foot into a healthier position with every single step — from the proprioceptive bubble surface to the deep heel cup.

The biomechanical features support both the medial (inside) and transverse arches. The footbed is soft and cushioning, bringing comfort with every step!

The three velcro straps secure the sandal durinbg running, playing or jumping. And the anti-slip insoles guarantees proper grip, even on wet surfaces.

Before & After

See the difference proper alignment makes

Footlogics has been supporting little feet since 2008. Our podiatrist-designed 'Arch-Up' sandal brings the biomechanical features found in expensive adult orthotics to a lightweight, fun summer sandal for children.

Without support: excessive pronation

Ankles roll inward, arches collapse under bodyweight. Over time this can affect posture, gait, and comfort throughout the entire lower body.

With Arch-Up: natural neutral alignment

The deep heel cup and biomechanical arch guide the foot into proper alignment, reducing strain on muscles and ligaments while supporting natural development.

Arch contact with every step

The raised arch contour makes contact with the arch of the foot — providing the same support children get from orthotic insoles in their shoes, now in a sandal.

Real parents. Real results.

Flat Feet

"I honestly cannot say enough good things about these sandals. My 6-year-old has been wearing Footlogics orthotic insoles in his shoes for the past year, and I was dreading summer because I knew he’d want to wear flip-flops in the hot weather. Finding these arch-up sandals felt like a miracle. This sandal looks very supportive and stable with the deep heel cup and good arch support. I noticed how they stop his ankles from rolling inwards. He’s been wearing them every single day for three weeks to the playground, the beach, the shops and he hasn’t complained once about tired legs. Our physical therapist said she’s genuinely impressed. Worth every cent and then some."

"My son wears custom orthotics in his school shoes, because of his flat feet and I was so worried about summer — but these sandals give him exactly the same support. He's actually excited to wear them because they look cool. Win-win for both of us!"

Heel Pain

"We tried every sandal going. My daughter has low arches and her physio said she needed support 24/7. These are the only sandals that actually have a real arch built in. Three months on and her heel pain has completely gone. I only wish I'd found them sooner."
