The upper on this particular XT style is foam/plastic/leather sewn together.  If you look closely at the pic you'll notice no grain pattern on some of the upper pieces.  I also purchased the CC/BLK color of these sketchers and they are complete leather sewn together upper.  IN THIS PIC, LOOK AT THE BLACK/BLACK color above - THEY HAVE ALL LEATHER UPPERS.  The Black with gray inside DOES NOT!!!
