Little City connects and builds a circular economy through the use of gamification, enforcing Nike consumers to do more for their communities and creating a long-lasting love for the Nike brand. The love for Nike brand is created via restoring certain/all parts of your memorable shoes with Nike Grind material. Little City immerses clients in this experience through an Interface Application viewable to all mobile devices.

We love, treasure, and care for our Nike shoes. Wear and tears are part of the journey in any shoes; we wanted a way to bring those memorable shoes back to life as well as extending the use. Little City provides this solution by allowing Nike consumers to select the shoe parts that they want to restore, selecting Nike Grind materials to be that new replacement and earning sustainable points. Sustainable points are also collected from helping the communities, going to Nike sustainable events where consumers can unlock special soles, mids as well as a whole new shoe.

With the use of the New Circular Design Guide launched by the Ellen MacArthur Foundation and IDEO at Davos, we were able to talk to consumers, gain feedback on the unique value proposition in the quality of Nike Grind materials. Our market insights from interviewing over 40 people suggest that people value their Nike shoes and miss wearing them out. By creating a new service allowing consumers to restore and upgrade their most valuable shoes though highlighting different benefits in each sustainable Nike Grind materials, we hope to also raise awareness and community bonding as well.
