I'm also waiting on the pebble grain upper boots, but Leaves just said in the Carmina porn thread that the pebble grain is out of stock at the moment, and he's hoping for (but can't guarantee) a restock in mid January.
Sigh. Me, too. Mike never fails to surprise (and impress). Can't wait for those Ruby brogues. As for the austerity boot, it'll be a tough call between Cognac and Ruby for the shell option. Black calf for the all-calf option sounds lovely, and I think a calf/Scotchgrain would be quite nice for a combo; we've had a few calf/suede makeups already, and (just my opinion) I don't like the idea of calf/shell mixes.
