Introducing the kids' prio running and fitness shoe. This shoes is a barefoot shoe with all the great features of the adult version plus a few changes made just for the kids:

  • 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.
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, that feet are supposed to
  • 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 — The “inverted V” straps aren’t sewn down so you can 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

Backed by Xero Shoes 5,000 mile sole warranty.

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.

A note about sizing:

We recommend buying the Kids Prio in your regular size.

The “12 Kids” is the smallest size, followed by 13 Kids, then Youth 1-4.

Also available in adult sizes on request.
