I would die trying as those are beautiful.
My tallest shoes are a pair of Jimmy Choos at 5" without a platform. They are beautiful. Of course I'm not going to trot around for blocks in them but they are surprisingly comfortable. My others that high, have platforms. For me it's not necessarily the heel height that is the critical factor. Sometimes it's more to do with the shape of the shoe. Haven't quite figured it out.
I love shoes, flats, stlllettos, everything between. I do think mid heel shoes 3-4" are becoming more readily available and popular with the higher end designers.
