I only have one pair from the exclusive line. I could not be happier with the quality of the leather used. It is comparable to the leather used by G&G. Superior to that of C&J benchgrades. It's a soft tannage with lots of depth and it takes a polish quite well. (I presume it is chrome tanned and vegetable retanned/dyed but do not know for certain.)
The workmaship/craftsmenship is more or less benchgrade standards on the uppers and the sole treatment/finishing closer to handgrade standards.
All in all a really excellent shoe - I'll be happy to own more.
