Melissa shoes are 100% made in Brazil by Grendene that is one of the world’s largest manufacturers of synthetic footwear that has over 40 years of experience. 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. Due to the nature of our MELFLEX™ material and the production method of certain styles, some items will have irregular swirls, patterns and sometimes, textures. However, these are not considered faulty and is in fact, what makes Melissa shoes unique. If however, your shoes are indeed received incorrectly or are faulty, we will do our best to make it up to you !
