I've been using these boots pretty much every day for the last 5 months and so far they have been great! I've worn them in temperatures from plus 10 to minus 30s and on the most part they keep my feet warm and dry (i do find standing in knee high snow all day does result in my feet being a tad damp but not too wet). They're light and comfortable which as I'm moving around outside all day I find very novel. I keep them clean and polish every so often and they remain sealed and soft. All round I could not complain.
