They do look like faded #8. If these are really faded shell though (any color), look under the tassels. Every display pair I've seen has remained darker under the tassels. If the color is even throughout the vamp then I'm not sure what these are.
Whatever the case, faded or not, they're lovely and I'd be very tempted if they were a 9.5!
I shouldn't have instakopped the RL C&J tassels during the last 40% off sale. Won't make that mistake again.
