   If it is capacitive, it is capacitive. Did you read where I mentioned   
   you shoe acting as the dielectric of a capacitor??   
      
   Alternatively, the three leads out of your box could be...   
   1.	the high tension lead,   
   2.	the power supplies (low) voltage lead, and,   
   3.	the common (earth) rail used by both the high tension supply and the   
   low tension supply!!
