Running Shoes for Girls, Made for Growing Feet
Girls running shoes that fit across three EU sizes instead of one, built on a patented expandable sole. A pair bought at EU 29 still fits at EU 31. Measure her longer foot, order that length, and add to cart. Every order ships with an Aretto foot scale for the next size check.
Get Her Size Right Before You Add to Cart
Order on her measured foot length and the pair that arrives will fit. Buy for length, not for age, because age is the least reliable number on a shoe box.
Take her longer foot, add the toe room, and order that length. Running shoes need more front room than shoes she walks in, because her foot slides forward every time she lands.
Width counts as much as length, and children's feet vary more in width than most size charts allow for. A systematic review of children's shoes found that children's shoes need to come in different widths, and that younger children do better in shoes as flexible as their own feet.
Running shoes for girls' sizes use the same Aretto system as the rest of the store, so one measurement covers every pair here.
| Aretto size | Age band | Foot length | EU | UK |
|---|---|---|---|---|
| S1 | 1 to 2 years | 12.1 to 13.4 cm | 20 to 22 | 4 to 5.5 |
| S2 | 2 to 3 years | 14 to 15.3 cm | 23 to 25 | 6 to 7.5 |
| S3 | 3 to 4 years | 16 to 17.3 cm | 26 to 28 | 8.5 to 10 |
| S4 | 4 to 6 years | 18 to 19.3 cm | 29 to 31 | 11 to 12.5 |
| S5 | 6 to 8 years | 19.9 to 21 cm | 32 to 34 | 13 to 2 |
| S6 | 8 years and up | 21.6 to 23.3 cm | 35 to 37 | 2.5 to 4.5 |
Measure in the evening, when her feet sit at their largest.
Between two Aretto sizes, take the larger one. The shoe expands into the gap, and a tight shoe stays tight.
Full conversions sit on the kids shoe size chart.
What You Get for the Money
Five things do the work here, and each one is something she would notice on the way to school.
A breathable knit upper
Infiknit™ is a 3D-knitted upper in a soft polyester and spandex blend that stretches in every direction.
It flexes with her foot as she runs instead of pressing against it, so nothing pinches across the top or at the sides.
A sole that opens as her foot lengthens
Supergrooves is a patented sole with an inverted Y-shaped groove pattern that widens and lengthens as she grows.
The pattern holds its grip as it opens, so a pair at the top of its size band still grips the way it did on day one.
A memory foam insole
SquishyFoam is a high-density memory foam insole that compresses under each stride and springs back.
It is what makes these comfortable running shoes for girls over a full afternoon rather than a single lap.
A sole that sits level from heel to toe
There is no raised heel here.
The heel and the toe sit at the same height, the way her foot stands barefoot.
A wide toe box
The front of the shoe is wide enough that her toes stay spread when she puts weight on them.
That matters most while she is running, because that is when her foot spreads furthest.
All five come as standard on every pair above, so the decision left to you is size and colour.
The same knit upper and expandable sole run through our girls sneakers if she wants a pair for days she is not running.
Black or White for School?
Colour is a laundry decision before it is a style decision.
Black hides a wet playground and clears most school uniform codes, which makes it the safer buy for school wear. White looks sharper out of the box and shows every bit of that same playground.
If you are weighing up girls black running shoes against girls white running shoes, her school list usually settles it for you. Both sit in the full kids size range, alongside the other colourways above.
Whether she needs a running shoe at all, or girls trainers she can wear anywhere, is a fair question before you buy. The walking shoes vs running shoes comparison settles it in a minute.
When to Buy a Different Shoe
Three situations call for something else.
Studded boots for football and spikes for athletics are built for a different surface. Formal assemblies with a strict dress code usually want plain leather. If she is mostly walking and sitting rather than running, the everyday range will cost you less to replace.
For game-day studs and the wider activity range, look at kids sports shoes.
Three EU Sizes in One Pair, One Price
Every Aretto size covers three consecutive EU sizes, which changes what a pair is worth.
Pixl Pixel Berry in size S4 fits EU 29, EU 30, and EU 31, a foot length of 18 to 19.3 cm. Buy at 29 and she is still in the same pair at 31.
Children rarely announce that a shoe has gone tight. They stop running in it first, which on a running shoe defeats the purpose, so check the fit every two to three months.
Delivery, Exchange, and Warranty
Orders usually arrive within 5 business days, or 5 to 10 days outside the metros.
A size exchange can be requested within 10 days of delivery, with free pick-up in most locations. Keep the original packaging ready for that pick-up: the shoe box, the foot scale, the shoe tag, and the butter paper. Exchanges are valid once per order, and only size exchanges are accepted, not colour exchanges.
Returns also run to 10 days.
Every pair carries a one-year warranty covering sole pasting and stitching defects, though not ordinary wear such as fading or worn-out soles.
Full terms sit on the shipping and refund policy.
Add Her Pair to the Cart
If she is on a hard playground and a school field in the same week, take the black pair and save yourself the washing.
If she is mostly indoors for PE, the white pair will stay looking new longer.
Either way, order the size her measurement gives you, and take the larger one if she sits between two.
