It's interesting how it can change in some places and not others. The idea of Aigle becoming at all popular is just so foreign to me. Rubber boots may be replaced as a style here, but the specific brand Hunter never will. It's British, so people like that, and it's more importantly ingrained - like Fussells cream, Tetley tea, or Eversweet margarine, Lamb's Rum, Blue Star beer, Maple Leaf balogna, Jam Jams, Purity syrup, or pull-tab lotto tickets, etc. Things that reach that status here never get replaced
unless the product is literally no longer produced. Not many things achieve that status, of course, but once they do, it's done for generations.
