On is a Swiss footwear company that produces high-performing running sneakers, with a strong focus on sustainability and recycled materials. Using the brand’s own CloudTec® technology, On crafts green trainers with an adaptive outsole that responds to the stimulation of running, and avoids muscles to be stressed. The project CleanCloud™ tells the other side of the brand, as it deals with the environmental issue through alternative methods and innovative approaches. Following the respect for nature grounded in the nord-European culture, On turns carbon emissions into high-quality running sneakers. It represents a further step forward compared to Cyclon, the subscription service that gives the subscribers a pair of eco-sustainable shoes every three months, completely free. Driven by the suggestions of a team of biochemists, On CleanCloud™ brings the idea of green footwear to another level. This breakthrough system captures and converts carbon emissions into chemicals, later used for producing On sneakers and running shoes.
