EXCLUSIVE AT NET-A-PORTER. Reformation’s rugged ‘Katya’ combat boots are made from textured-leather produced in tanneries certified by the Leather Working Group – the organisation assesses the environmental impact of leather production by driving supply chain traceability and reducing waste generation. Set on a recycled rubber lug sole with a slight heel, they have a rounded toe and waxed cotton laces. Wear yours with denim and day dresses alike.
