New Big Feet Holder

The third-place winner in the Design Lab contest, Happy Feet, deploys charcoal and ultraviolet light to rid shoes of bacteria and kill off smell. Sang Hoon Park and Kim Jong Hyun, students at the Korea University of Technology and Education, designed the unit to look like a flower to reinforce the idea of freshness. Happy Feet has room for four pairs of shoes, and sensors activate the system when shoes are put on the device.
