I've always used a product called Dubbin to do my boots with. It really stands up to the seacoast conditions I tend to find my feet traipsing through, and that it smells of bacon fat doesn't exactly offend me.
I have been hiking many years, but I have not heard of this product. Thanks for posting the information about it. The bacon scent is the main selling point for me.....!
Yea Nikwax is what I use also. I also agree with what you said about Bacon smell on your boots....smells to me some critter would love to sink there teeth in those boots.
