Ok , well this will be pretty much an opinion poll of sorts. I want to know what everyone has done to prevent or eliminate the dreaded black shoe stain on left shoes from the shifter. I have had 3 bikes that have all left an oily residue on my nice white running shoes that pisses me off. I'm curious what many do to either eliminate this problem in a way or try to eleviate the symptoms by some means. If there is a trick out there I want to know about it and I want you to share it with our brothers. Please no bull sheeit replies. Honest question with honest answers.
