text: begging u to tell me this plzzz>>>does copper prevent stink in shoes>>>>>>? answer this properly plzzz and i will get u a best answer:) like silver (used in socks), copper could be used as a biocide to limit fungal growth which causes the stink.  unlike silver, copper would have side effects and would react with sweat and humidity, mostly oxidizing and turning things blue.  this would limit or eliminate copper's usefulness for this purpose.
