Some of you will remember my recent thread about Dr Martens boots. I ended up finding a pair of the shoes, made in England, in my size looking almost new at a thrift store for $10, and they are performing their task (work shoes) nicely. They actually look pretty good too. I have a question for the leather experts, however. These have the 'greasy' finish, which I like. I want to maintain it and protect it, but when I tried regular shoe polish, it made them shiny, which I don't want. Is there something else I can use on these to keep them looking properly greasy? Thanks.
