I have been using the mac method. brush brush and wipe with cloth.the shoes are about 2 years old? Maybe 3? They actually don't get worn too much. Maybe only about once a month. the indy boots get more usage.I just noticed these little bumps around the creases of the cordovan shoes last night so I was wondering if the leather was drying out or maybe it is the "bloom" that I've seen mentioned. Will brushing get rid of them?
