OK here's pics of my Addisons since I cleaned them up a while back. One thing you will note is they have lightened back up. As I said before boot oil will darken it a bit but over time as it dries the color lightens back up. Another thing to keep in mind is all vegetable tanned full aniline leather darkens (includes Chomexcel which is both Chrome and vegetable tanned) over time. The lighter the color of the leather the more pronounced this will be. I've seen natural and tan colored leather turn a deep golden brown after decades of use. Obviously the darker the color the less pronounced this will be.
More scuffs, more mud and water but still going strong. I said I was going to take pics during yesterday's dig but I was too busy digging.
Side view. I'm thinking the right foot toe box is darkening faster because of all the "toe digging" I do. Most of my field boots show the same sorta thing.
My basic dig kit. Good boots, a Filson shell bag, a Saddleback satchel and some light digging tools. In the satchel is a camera, notebook and pencils, a knife or two, Surefire flashlight, cell phone and of course a pistol. The easy pickings on this site has been done. Now you have to dig to find anything or wait for a gully washer rainstorm to find anything. Four hours of digging and I managed to find some hammerstones, a grind stone, some broken points and so on. Anyways....
As everyone already knows I wear or use all of this stuff in the field and I do not baby any of it. Whatever the weather or conditions when it's time to go it's time to go. All I do is maintain this stuff in a manner fitting to how I use them.
Maybe next time I'll have someone with me and can get some pics of boots in action.
