My field boots are a few years old (I think 5 or 6 now) and I've noticed dry spots on the inside of them where it made contact with the saddle and the horse. I'm sure doing bareback classes on a sweaty horse didn't help!
It looks like they are just dirty, but it doesn't come out with cleaning. When I polish them, they look great, but when the oil dries a bit more they appear again.
While you can't see them while I'm riding, it bothers me! And when I do showmanship classes, it looks like they're dirty.
Any advice? I have neatsfoot oil and mink oil on hand.
