I'm not sure there is an alternative?
I mainly wear trainers and dresses and leggings (even though I know leggings are probably deeply unfashionable) but I have a few nice black dress for the winter that I would wear with black tights and trainers don't really go. Every year or so I buy new black or burgandy Chelsea boots.
I generally wear lace ups/brogues for work every day so that wouldn't feel good for weekends.
Any suggestions or do I just start searching for new Chelsea boots?!
