Those are really hot... if the soles really are 3/16" stainless as they appear to be, then that's actually a pretty good price (yay Chinese labor)... that is NOT easy to do.
BTW the company considers every pair of steel sandals to custom work, so if desire > cash, call em up, One poster mentioned the toes curving, http://www.orientvisual.com/6inchforever/gallery2.htm shows the rest of their styles
they will also make up any shoe in any style and material you want (found that on their main site). it's not that hard to walk on 4-5" heels, if you're used to it. i can wear them all day if they're well made and comfortable.
"...those shoes are three hundred f**king dollars...let's get them!"
