I used to have really bad foot odor. Many years ago I paid the $20 bucks to get that information. I have been using the 70% alchohol every day since then and I no longer have foot odor. I just put it in a spray bottle and spray it on my feet before I put socks on or before I wear sandles. You are right about it drying your feet out. Just my heels are really dry. I'd rather have dried out feet than stinky ones though.
