Rubber is gas permeable. Odor is gaseous in nature. Go figure...

I bought a pair of Rocky SCS boots, and can honestly say after wearing them for two full seasons, they have no discernable odor to me.

They're breathable to let moisture escape, and have a treated lining to prevent bacterial growth which apparently works very very well.

I start with clean and de-scented as much as possible feet, socks washed in sports wash, and use a pair of Dr. Scholl's odor eater inserts.

I've had both does and bucks cross my entrance path nose down and show no sign of alarm. In the past, this was never so.

I think the key is clean feet, and boots that prevent bacterial growth from generating odor. This combo has worked very well for me.

I have no doubt deer/dogs could detect or trail me if they were so inclinded, but for hunting deer, I don't seem to be leaving any odor that alarms and puts them on the offensive.
