As you know, narrow shoes are a thing of the past, which is why Mustang Free is the respectful footwear for children that has everything their feet need for natural growth.

I'll tell you more about it below.
Mustang Free Kids, the barefoot shoes for play you’ve been waiting for
You’re looking for respectful sneakers so your little one can play with total freedom.
And of course, you want them to be comfortable, durable, and easy to put on and take off.
They should meet all the barefoot requirements, but also look great in and out of school.
What requirements should they meet to be barefoot or respectful?
The Mustang Free Bolt has it all. Because they feature:
- Wide toe box: so toes can move freely.
- Zero drop: supports the natural development of their feet.
- High flexibility: better balance and more natural movement.

Mustang Free Bolt. Lightweight and durable
Made with high-quality synthetic material inside and out, they are 100% vegan.
Their lightweight and durable fabric adapts to the fast and constant movement of play.
Plus, the stitched rubber sole resists the abrasion typical of playgrounds, extending the life of the shoes.

A quick and simple fit
The system combines elastic laces with a velcro strap.
No need to tie anything: just open and close the velcro for a perfect fit.
That way, your child can put them on and take them off alone, without asking for help.

A sole designed to feel and endure
Thin enough to keep sensitivity, yet resistant enough to protect.
With a specific tread pattern that ensures grip on the playground and boosts agility.
Your kids will enjoy running, turning, and kicking with all the energy inside them.
Play leaves its mark, and it’s normal for the shoes to show signs of wear from the very first uses.
Because movement and health start with their feet.
How to clean and care for your Mustang Free Bolt
- Wipe with a soft, damp cloth after each use.
- Remove dust, sweat, or playground residue to keep them in good condition.
- If you decide to machine wash them, use cold water and always let them air dry in the shade.
