The Charlie sneaker is a big first for Louis Vuitton. Not only is it the first couple shoe but also the first eco-designed shoe. Made with 90% sustainable materials, the upper is crafted from a mix of recycled and bio-based materials, while the outsole comes from recycled rubber. As an exclusive for Chinese Valentine's Day, it features either a gold or silver accessory that forms the perfect Monogram charm when interlocked. Gold accessories are found on women pairs and silver accessories are found on men pairs. For any questions, please contact customer service.
