Aesthetically speaking, my favourite pair are my Pleaser Sexy 20 in red patent.
But they are incredibly hard to walk in, due to the 5"+ vertical heel. So my next favourite pair would be my black leather Pleaser Seduce 420 with 5" heel. They have a classic stiletto heel shape so much easier to walk in. Unfortunately they don't photograph well, so still trying to get a good shot that does them justice!
