Footwear and apparel brand Allbirds has collaborated with luxury womenswear brand, Rosie Assoulin. Both brands have a shared appreciation for natural materials. Through their synergistic passion for sustainability, they’ve joined forces and created the Allbirds x Rosie Assoulin Sugar Slider which is made with a sugarcane-based foam, SweetFoam, giving consumers a shoe that’s comfortable, stylish and has a low impact on the environment. In honour of this collaboration, Allbirds and Rosie have come together and made a donation to two organizations, the Ron Finley Project and Rodale Institute. This collaboration was inspired by those nostalgic, summertime memories from Rosie’s childhood summers in Brooklyn, and is available in two colourways: Cherry and Pistachio.
