KEEP THEM CLEAN:
Wash your feet more often and arduously than you’re used to, with anti–bacterial soap.
USE A SHOE TREE:
Yes, because an unvarnished cedar shoe tree (See: Woodlore Adjustable Shoe Tree) , properly inserted, will absorb perspiration, help prevent bacterial growth, and deodorize shoes.
USE AN ANTIPERSPIRANT:
Ok, I get it you want a much easier option! Why not try a pair of loafer socks (i.e. “no-show” socks)? They absorb the perspiration, and no one sees them. There you go!
