Product Details

The Chicago trainers are made from 41% Sorona®, an innovative fibre derived from corn production waste. Unlike other traditional synthetic fibres that are derived from petroleum, this fibre is produced from natural and renewable resources, significantly cutting down on greenhouse gas emissions. What’s more, they’re made from 59% recycled polyester that comes from plastic bottles from the ocean (ocean thread). These trainers follow the Global Recycled Standard, combining fashion with quality, comfort and environmental commitment.
