Howdy y'all, I have 9" tall all leather boots that I use for outdoor anything; including hunting. I have always been happy with leather oil to keep my boots supple and waterproof / resistant. I started looking at snow seal since I will be in the snow this year and not just dealin with water. Does it let the boot breathe or does it seal it more like a rubber boot? I don't want to apply wax to my boots with a hair dryer only to find out that I ruined a $200 pair of boots. Anyone with some experience on this?
