Looks like unmarked shell cordovan, also unmarked for size... only $20.
I took a flyer on these....never had a bit loafer before!
No clue what type of leather this is, at first glance I thought it was embossed but changed my mind, would like to invite the experts (ya'll know who you are!) to take a look and ask what you think about the leather??
Alternatively, please feel free to tell me how great and stylish they look
