Start with quality Goodyear welted leather boots. Be sure the size is right. Brush off debris and keep them in a cedar shoe tree when you aren't wearing them. Don't wear them more than one day in a row. Condition the leather a few times a year. Have a cobbler replace the heel and sole every few years as they wear down. That's your recipe for boots that last forever.
These brands are excellent quality, but they are ultimately fashion boots. Their styling will change over time. The classic black wellington, however, has been in the same cool classic style for decades, thereby defining the Hunter boot a true buy it for life(BIFL).
