Hi there, pardon my ignorance coz I haven't done any research on leather shoes before.
Is there a difference between polished and calf leather?
"Polished" leather has a plastic-y finish. It has an unnatural shine. There is either no grain or sometimes, an embossed grain. It breathes more poorly and ages badly. The finish can be damaged or even flake off the leather below due to the added layer of plastic-y chemicals on top of the leather. Acquire a pair of full-grain calf leather shoes rather.
