security?

my biggest beef against the airport security bureaucracy is having to take my shoes off  . not every airport has ample space for people to put their shoes back on. my main paranoia  about taking my shoes off for security is the  fear of contracting athlete's foot. has anyone heard of anyone catching athlete's foot from walking shoeless through security?  in the summer when i wear sandals sometimes i will wear peds through security and when i  put my shoes back on i take them off. i know i am paranoid, but i feel like the airport security should be able to assure me that  i wont get athlete's foot before i go barefoot through the terminal.
