Nobody unites fashion, form and function quite like Adidas. Specialising in sneakers and streetwear, the mega-brand has become a symbol of sports luxury. These black Boston R1 suede sneakers from Adidas feature a lace-up front fastening, a round toe, three signature stripes to the side and a flat rubber sole. POSITIVELY CONSCIOUS: Adidas Group scores 4 out 5 by independent ethical brand rating agency Good On You. It uses eco-friendly materials in many products - 100% of its cotton is from sustainable sources and it's committed to use 100% recycled polyester by 2024. It traces and audits almost all of its supply chain to ensure good labour standards, and has committed to reduce carbon and water stress across its whole supplier base.
