Who manufactured your brogans??......From what I have researched, it depends on the maker.
Thirteen years ago, I bought a pair of Fall Creek brogans. I soaked them in water overnight, then wore them at home for several days. Once they dried, I oiled them. After 13 years, I now need a new pair and they were a comfortable shoe!.....On the other hand, I know a guy who wore his brand new pair of brogans (I don't know who made that pair) through a creek at Gettysburg......they fell apart and became worthless......
Now that I need new brogans, I think I may order from Fugawee, who claims that theirs do not need to be soaked in water first.
I think different people will have different experiences and will advise you accordingly.
Good luck!
