Daily energy routine in rubber shoes - still works? and how well?

[Guest guest]

Hello,

 

On a scale of 1 to 10, how well do you think the Donna's energy routine works

for you if it's done in rubber shoes vs outside with your feet touching the

ground?

 

I ask because I recently saw a video from David Wolf on youtube talking

referring to rubber shoes as " The World's Most Dangerous Invention " . Apparently

they block the earth's EMF field and that's a bad thing.

 

I am usually in rubber slippers but I think that being on the 5th floor of a

city building it probably does not matter anyway.

 

Thanks.
