Both the material and the manufacturing process of these shoes, which are knitted using 3D technology, are designed with sustainability in mind. The outer material is made from recycled coffee grounds, from which dye-free, quick-drying and odour-neutralising fibres are obtained. These are then knitted – a technique that avoids environmentally harmful production waste. The functional 3D pattern means that the comfortable, everyday shoes with non-slip sole and reinforced heel are particularly breathable.
