Melissa is not just art, fashion and design. It is also about sustainability. Melissa shoes are made with its own trademark material, MELFLEX™, a type of PVC that is 100% recyclable, flexible, resistant and comfortable. Melissa products do not contain any component of animal origin, or go through animal-testing throughout its entire process of production. Today, its iconic jelly shoes are now officially registered as vegan-friendly by The Original Vegan Society.
