Go to a thrift store. Find a pair of boots that can be cleaned and treated with mink oil.
Or you can buy a pair of Red Wing Iron Rangers, which are more than $200. They’re made with quality leather, have good design and construction, won’t fall apart, and will hold a patina. They can last you for the rest of your life if you take care of them.
You’re going to have a very difficult time finding fashionable, well-made boots for under $200. What you’ll get, instead, is a pair that look cheap (and are cheap, having been made with inferior leather, if they’re made with leather at all) and/or fall apart within a year.
