This shiny leather debate...I was asking my dad about it because he has owned/worn plenty of suede/nubuck boots at his for many decades. I asked him how does the nubuck or suede turn out to be like that shiny material but not quite at a full leather feel. He says that in time he uses this type of suede lotion and he rubs the material with a cloth for years and it turned out to cut down the small brush feel of a suede or nubuck just small enough to reach to that leather look; still a bit rough and nubuck feel to it just worn down.
Idk if it helps the discussion but yeah.
