Okay, I thought this would be an oddball topic and question, until I did some research and found this topic mentioned briefly in other threads, mostly about whether or not to wear shoes in the dojo.
Sweaty feet

... they're not pretty and they can cause problems with footing, stability, range of motion, and self-confidence. What to do?
I've researched some suggestions from wearing footgear, to applying deoderant, to utilizing vitamins/minerals (such as magnesium), to botox

as aids against the issue of excessive sweating of the feet. I've thought of taping my feet as well, but that then affects the development of callouses, grip, etc.
So, does anyone else have this issue and any suggestions or anecdotal confirmation of certain solutions mentioned above?
