Sustainable barefoot trainers made from 80% plant-based materials. Wide toe box, zero drop sole and velcro fastening give little feet natural freedom of movement from playground to forest path.
MURIS Petra – trainers that grew from the earth and head into the world with your child. Petra is barefoot footwear that combines sustainability with maximum comfort. Made from 80% plant-based materials – the upper from grape waste, the lining from corn – they're lightweight, breathable and kind to nature and to growing feet. Petra is light, flexible and ready for every step – from the playground to the forest trail.
Thanks to the wide toe box and slightly higher cut, little toes have plenty of room and protection. The reinforced heel and toe can handle the biggest adventures, whilst the thin rubber sole with zero drop supports natural movement and ground feel. No heel stiffener – for complete freedom of movement.
