These pictures of the shoes I have found on dezeen.com. I saw those shoes and I thought OMG, how HYPE it would be to wear them.
These shoes are designed by the Italian based Brazilian designer Andreia Chaves, http://www.andreiachaves.com/
The so called "Invisible shoe" are more an object than a functional piece of footwear.
Well, functional or not functional I think they are hot for sure! ;)
