I have the Kirby Carmina boots in hatch (Russian Reindeer) and it's a striking leather. Maybe it's just that I'm used to seeing it in boots that it looks so odd in a shoe though. But, it's definitely more striking than a shell - which seems to take years before you truly see the character. I have bourbon shell boots from Carmina and they're very nice but after 2 years the leather just doesn't have as stiking an appearance as some other leathers (including the hatch grain). Not sure I helped any, but that's my opinion
Interesting, what exactly are the qualities of that leather, i'm leaning towards it as well but I have never seen it in person. Is it oily does it take any shine at all? What are the differences vs normal calf leather (to understand durability). Would appreciate your input as you have that from Carmina.
