Seems like I remember it being around $12.00/gallon and can be purchased at most any store TAC shop that sells horse riding equipment. Its used for saddles mostly.

I placed a trash bag in a fruit box placed my boots in the bag and filled it with oil until it was over the top of the heels. I poured the oil into the boot as well so it soaks in from both sides as well. My jungles are soft as slippers, well almost. It also dyes the leather thru-and-thru. No more covering up dings and gouges in the leather with polish or leather dye.

I dont know if I would try soaking the Belleville/Wellco boots though. I am not sure what effect it may have on the liners. You could try rubbing it into the outside leather though or soak them without pouring the oil into the boots.
