BLUE DUKE TRAINERS
The Duke trainers are made from 100% recycled polyester from recycled plastic bottles that we then transform into fibres to offer top-quality and environmentally friendly footwear. This allows us to give a second life to materials that would otherwise be considered waste. These trainers follow the Global Recycled Standard, combining fashion with quality, comfort and environmental commitment.
