My turn to axe a question.

I've got some Redwing 1907s I want to winterize. I had an old italian tube of somethin'-or-other that I got with my Scarpas, but its run off somewhere. What are you woodsmen (urban or authentic) using on your boots? Nikwax? Something else?

I wouldn't mind the color getting a little richer, but don't want to go too dark. Whatever I try will be tested on the inside ankle of the boot first.

Thanks in advance,

C
