The other steps may indeed help, but freezing the shoes isn't going to achieve anything except stop them getting any worse while they are frozen.xilios said:Here is the link that I found at yahoo ( among many others), still makes more sense than just letting the shoes out to dry, till the next time you use them.
If you look at the first half dozen Google pages you will see that lots of individual postings recommend freezing but all the authoritative ones - e.g. council Environmental Health pages - say, 'no, you can't sterilise anything by freezing it'.
