They are used 5 days a week, I catch a bus to work, walk around the office etc.  and catch the bus home.  The tread has worn down quicker than what I would expected from Dr Martens  but they are not the docs of old, I should know as I have many pairs of the original English made Dr Martens.  No one makes a product which will last for ever as they will go bust.  They are nice to wear, look good and they still project that little rebel in all of us.  Buy them, wear them, replace them and then buy some more.  Treat yourself, life’s too short to wear sneakers……
