I was never quite too sure why shoes that are somewhat like flesh coloured are called 'nude'. But they are. According to the accompanying text these are nude 5" heels, and judging by the heel I would say that mean a actual foot-fall 5" (5" from the ball of the foot to the centre of the heel). So the full height of heel with the platform is probably more like 6" because that looks like about a 1" platform. But it is hard to tell with 'hidden' platforms.
This babe also looks very familiar. I think she is a film star or some kind of celebrity.
