Product Info

Kids Urban Play outsole
Grip meets flexibility for kids who are finding their balance.

NO INSOLE
No insole, bringing you even closer to the ground for a greater barefoot experience.

BREATHABLE MESH

VEGAN*
*The main materials in all our Vegan* products are synthetic and aren’t derived from animals. We don’t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we’re not yet able to guarantee it and want to be fully transparent.
