Is there a recommended oil/leather treatment for these boots? Like many have said, the leather scuffs rather easily, and I really want a nice amber to it much like the Iron Rangers. However, I've looked around and found that products like Neatsfoot oil darkens the boot quite a bit, making it look almost black.
Any real oil/wax treatment will darken any leather, I've never seen one that didn't warn about this specifically on the packaging.
Also, from my experience with my own, (which are the previous lighter ones and not the newer darker ones), there is really no way to stop them from getting darker and darker as they age. When I first dubbed mine they were much lighter than they are now two years later, after regular wear and redubbings, though mine are certainly nowhere near black, especially in the light. Even before I dubbed them and wore them unoiled or waxed for a few months, they still got darker as wear and tear smoothed out the leather, especially around where jeans or pants hit the boots.
Basically if you keep the leather oiled/waxed it will keep getting darker, if you don't or let it dry out, it will get lighter, but then again, this also threatens the longevity of the boots.
