You may think that you have seen something like this before; well chances are you are thinking about the Kito Keyboard shoes. They were stylish, from Japan and would set you back around £20 a pair, but these are not Kito shoes at all and they will not cost you £20 either!
These keyboard based shoes are Chinese and will set you back around 90p a pair, that if you can be bothered to go through all of the hassle of buying them from Chinese only site TaoBao, hopefully they are not wireless either because that could have all sorts of effects on the computers that you are walking past.
Priced at around £0.90 ($1.30)
