I'm sorry patrick but I am confused by your statement. Just a few posts ago you stated "If you want your shoes to last you shouldn't maintain a "shine" on the vamp of your shoe." so I am not sure what you mean when you tell this person to polish the vamp of their boot. Do you mean to say brush the vamp but don't use shoe polish, or use shoe polish but don't brush it? Since all shoe polish includes wax, brushing it will produce a shine (which is one of the intended purposes of the polish).
In regard to the boots in question, I would agree with grendel that it looks like the finish has worn off one boot and that perhaps adding some cream polish that is the color of the boot may help to some degree.
