The Shift Sneaker is a project by UK-based Rehabstudio as one of their Hackweek Projects so that shoe hoarders all over the world could get a handle on their collection. Instead of needing a shoe in every color of the rainbow to match all your outfits, with the Shift Sneaker, you only need one. Innovative textiles and wearable technology allows the wearer to customize the look using colors and patterns to match their clothes or their moods.
