Cycling sandals and effective disinfecting/cleaning are indeed pertinent to your OP. You state as much immediately before you dismiss my post as "not related". What an obtuse response! It is a simple matter to carry 20-30ml of bleach on tour, then use it to clean your stinking feet/socks/shoes. Please work on your reading comprehension and manners. If you don't like free advice, then don't ask for it. Now I know why you were on my ignore list.
