I noticed there are a lot of boots with scent blocking liners. I was wondering if anyone has tried any. I guess my question is are they as effective as rubber boots?

i dont know but im looking hard at those dream season boots

THe first product of theirs that made me wonder. As far as I can tell the liner doesn't come out. The stuff needs reactivation. I ain't putting boots in the dryer every other day. May not be as effective in the long run but probably more comfortable.

I think putting bread-sacks over you're feet before putting you're boots on would work just as well..... Or "not" work as well.....

I've done that before, my feet felt warmer too. Any odor that escapes your boot will do so via "chimney effect, and there isn't much you can do about it other than reduce the source. Scent free antiperspirant on the soles of your feet and baking soda help a lot. Don't waste that much money on something that only works temporarily when baking soda is 50 cents per pound and works better.
