My feet have been growing for the last couple years, so I stuck with cheaper boots that my mom and dad would get me. Problem is, they weren't very warm. I want to get a pair of boots to last a while now, and keep my feet from feeling painful and numb. In catalogs I see insulation from 200 grams to 2000 grams. Question is, how much do I need? I hunt in Mid-Southern Missouri, so temps aren't too bonechilling cold, but it can still get down there. I sit alot too with my grandpa, he doesn't like to move too far, if that makes any difference. Thanks for any replies!
