Snoseal does have a distinct odor. It doesn't bother me one way or the other. Dust sticking to the boots is normal after oiling them or waterproofing them. I think part of the problem is some are over treating them. Last year I treated my boots with oil then a week later with a light snoseal job. I wore them every single day for almost 8 months without treating them again. They didn't need it. I think some people are making the mistake of using too much oil/snoseal along with treating them far to often as well. Yes you can overdue it. It's not as bad as letting them go dry but rest assured more is not better. One of the simplest ways to deal with the whole residue grime thing is to wipe them down with some lexol cleaner every once and make it a point to brush them at the end of each day. Nothing ridiculous just a quick once over lightly.
Thanks for clarifying. You're right I've definitely been using less SnoSeal since I've started reading your posts and the situation has improved. And yea, wiping or brushing the dust off is really not a big deal.
I used shoe trees for awhile when they were new, but it was sort of a hassle to squeeze the shoe trees in there everyday so I stopped. Haven't used shoe trees in about two years and the shape of my boots is just fine. Then again, these are my rain/snow/mud boots.
I do throw in some cheap cedar satchels or cedar marbles after wearing my boots. They do nothing for the shape of the boots but help to manage odor and moisture. Works for me!
