>- there are no "toxins" in your body and none need to be "removed" from your body.
While I do not know about this machine, you are scamming as much as anyone else by saying that they do not have Mercury, Lead, Cadmium, etc in their bodies that need removing. How the heck do you know?
I do know that some detox methods do work, some better than others.
>- how would toxins, normally stored in your liver,
Not all toxins are stored in the liver, some are stored in fatty tissues, some concentrate in the brain, and some go to the kidneys.
>- If the toxins were in the bloodstream, you would also be bleeding all over the floor
Do not be rediculous. Various toxins can be extracted through the feet and other areas of skin by various methods without significant harm. Haven't you ever use a poultice?
