So I’m the type to always put my own spin on about anything I own. My street bike, my truck, our 4wheelers, my laptop, desk, gear, clothes, you name it. I’ve always modified my shoes and clothing just to be sure no one could be wearing the same thing as me. I would like to practice staining and marking up different shoe materials to see how it goes before doing this on a new pair. I’m looking to score some used shoes for practice however I’m not down with reusing an insole. I cannot find a solid supply of Nike replacement insoles. Anyone know of a good source?
