do you mean like foot bath massagers?

anything that deals with foot massagers, and even you can get
Cobblestone pads that massage feet too.
going for walks in grass barefoot is good stimulator as well
as grounding with earth, magnetically recharging.
Reflexology is more related to acupunture, accupressure etc,
but the charts are certainly useful for identification
o f foot pad placements as well for specific targeted areas.

if you are meaning using Ionized Water as a foot bath,
to draw out toxins
I am not SURE if it would...
but it would seem to me off-hand that it would,
since hot/warm water opens pores which helps draw off toxins.

also pascalite clay foot baths/ shin baths and epsom salt
warm food bathes help draw off toxins.

pascalite esp will draw off metals...
as do the foot pads.

Now you have my imagination going.. lol
I am wondering if we could make a compress/poutice
using Ionized Water and cilantro and mung beans
since both those help draw off heavy metals as well hmmm..
interesting ..
