Paint it blue: Gianni Bini shoes

I decided to spice up the soles of my silver glitter Gianni Bini shoes with iridescent blue-purple nail polish (Nicole by OPI: It's Up to You).  I used up half a bottle of the nail polish for this paint job alone.  Below are the "before" and "after" pictures. [For reference, these shoes cost $17 (reduced from their original price of $75), and the OPI nail polish $7.56.]
