Really it depends. I have a few pairs and the ones I use more often obviously get polished more frequently. I mostly just pay attention to the leather and treat them accordingly. I do, however, like to give them a once over with just the brush every time I go out.
I need some one to sip scotch with me, to listen to ska, to go to a shows, to not only listen to me go on and on about roller derby but have something to say themselves. Some one that wants spend all day in bed every once in a while. Wish I could find them..
