I am trying to get hold of some platform boots (uk) in a particular style..?

Black suede, and have like a block heel which is large from the top then gets slimmer, and the sole is about 1 3/4 inches. I have seen someone wear them and they look fantastic, I am sure they are designer but I dont know where to get hold of them from or ones similar, hope someone can help or give me any good catwalk website links for inspiration. thanks
