I will get my winchester boots today. Assuming they fit and I decide to keep them, I was told that I should polish them prior to wear to protect them. I went to buy kiwi mink oil but the label said not to use on delicate leather. I am not sure what delicate leather is, therefore I will probably take them to a professional shoe shinner and then polish them the next time. I was told to: 1. Use mink oil on the shoes. 2. Use black polish, obviously they are black. 3. Use the brush to remove the excess polish. Does any one want to give me any additional advice?
