Product Description

Now Xero Shoes are ready for you for KIDS!

You probably know how important it is to let your kids’ feet develop and function naturally — letting their toes spread, and their feet bend, flex, move, and Feel the World!®

That’s why we’re thrilled to release the Kid’s version of our best-selling Prio barefoot/minimalist shoe for everything they love to do.

The Kids’ Prio has everything you love about the adult version, plus we’ve made a few changes, just for them:

  • More grip! We spaced out the lugs and made them bigger on the FeelTrue® soles to give them better traction.
  • Ergonomic fit We didn’t just shrink the adult Prio, we changed the shape for a better fit.
  • Just-right feedback We also thinned out the sole a little bit to make it extra flexible, give kids the right amount of ground-feel and protection.
  • Unisex fit Don’t worry about boys vs. girls, the Kids Prio is made for both.

Of course, we’ve kept all the best things about the Prio:

  • Natural FIT — A wide toe box lets your toes spread and relax. Plus the “XERO-drop” sole (non-elevated heel and low-to-the-ground) allows for proper posture, balance, and agility
  • Natural MOTION — The Prio is flexible enough to let little feet bend, move, and flex the way, well, that feet are supposed
  • Lightweight — Your kids might even forget they’re wearing them
  • Natural FEEL — Remove the 3mm insole for a more “barefoot feel,” or keep it in for a bit more protection
  • 100% Vegan-friendly materials — No animal products are used in the Prio
  • Huarache-inspired design — The huarache-sandal inspired strap helps secure the heel
  • Adjustable instep strap — Use the “inverted V” straps aren’t sewn down to lock in the instep while keeping toes free to move
  • Reflective straps — The middle strip in the heel and instep straps are highly reflective for evenings and night
  • Barefoot-friendly — Wear the Prio with or without socks
  • 5,000-mile sole warranty — like all our FeelTrue® soles, the Prio is backed by our 5,000-mile sole warranty*

A note about sizing

The numbers for kids sizes change. The Kids Prio is available for EU size 30 – 34, and then jumps to 36. Above that, you may want to consider the adult Women’s Prio for the next size up.

Worried about your kids outgrowing the Prio?

We know that kids grow, and we’re not fans of buying shoes “that they’ll grow into.”

To help out if your kids get too big for their Prio, we’ve created a Facebook Group where you can trade/swap/buy/sell your shoes and pass your still-wearable pair to someone who still fits your size, and find a pair for the next perfect fit.

(Note: The FB group is for use at your own discretion. The deals you make are up to you.)

*5,000 mile sole warranty is non-transferable and only valid for the original purchaser of the shoes.

Caring for your Xero Shoes

To clean your Xero Shoes, hand wash with warm water, mild soap and allow them to air dry.
We do not recommend putting your Xeros in the washing machine or dryer.

Kids Prio

The Prio is an “all-around” shoe. It’s good for walking, running, hiking, playing, climbing… you name it.

That’s totally up to you (or them).

The Prio is made so they can be worn with or without socks.

The Kids Prio is “true to size,” so select the typical size for your child.

Now, that said, sizing is not a science, there’s a lot of personal preference involved… Three people with identical feet will have three opinions about how the same shoe fits 😉

If the size you get doesn’t fit, take advantage of our exchange policy. See https://www.xeroshoes.eu/return-policy/ for details.

All the straps — the heel and instep — are adjustable for a secure, comfy fit.

To use the instep straps, simply tighten or loosen them with the tension of the lace that goes through them.

For the heel strap, it’s best to adjust it by gently sliding it through the “wing” in the sole rather than yanking on it.

The Kids Prio isn’t waterproof. But the breathable mesh should dry quickly.

We know that children have a habit of growing.

We’ve created a Facebook group where you can find other “Prio parents” with who you can trade/swap/sell/buy. Click Here to see it (opens a new tab in your browser)

Note: We don’t manage the FB group. The participants in the group are responsible for managing all transactions.


After you purchase a gift certificate, you’ll be able to enter an email address for the recipient.

You can also take the Gift Certificate code and send it to the recipient.

Xero Prio Kids good but better if it were lighter.

So far so good. My son is really happy with this model because it's very comfortable and flexible but he would like wearing a lighter shoe.

Mes 2 enfants les adorent !

Seit Jahren für die Kinder

Für mich bzw. meine Kinder ein Schuh, der immer in der passenden Größe vorhanden sein darf 🙂 Perfekt für Frühling und Sommer. Nicht wasserdicht, dafür sehr leicht, bequem und robus.

Ma fille est super contente de ses nouvelles chaussures. Elles sont esthétiques, relativement souples et confortables, et ont l'air plutôt solide.
