I have found my polished shoes get dirty by the time i alight from the public transport. The sheen is lost and it looks as if not polished. so why not innovate a smart shoe that wud give back on its own the shine no matter how dirty it turns . polishing wud no more be a bother

Reward: A pair of shoes with the innovated polish

Any hints on how this should work? Just wondering if I should put this into the main category or into the Sci-Fi Pond.
