A year ago, I would have said that leather boots were akin to high treason when bowhunting. But, now, I feel differently. If you treat your leathers like any of your other scent free clothing then you are fine. This season I wore both rubber and leather, and never had my tracks detected. My boots live in a box with leaves on the bottom, never get worn in the car or anywhere else. I have huge feet (Size 17) and can't find any rubbers with insulation, so I need to wear my leather boots when it gets cold. Thusly, I have had to make absolutely sure that i keep them scent free just like the rubbers. I have had the same rubber boots for 4 years now, and the bottoms still smell just like the day I bought them. Not sure how that is possible, but I still don't get detected. Spray down, don't step in gasoline, and I think you're ok. If my feet stink bad enough for a deer to wind me from the odor coming out of my boots, I guess bowhunting isn't for me!
