Ack. I ran a marathon in the rain this weekend and forgot to dry out my shoes and left them in a plastic bag for 3 days. They now smell and could be mildewy or worse fungusy. Can these shoes be remediated or is it time to get a new pair? If they can is Lysol enough?
Sometimes it's better to light a flamethrower than curse the darkness.
If you're fortunate, the mildew or fungus may be localized to the insoles. Try taking out the removable insoles, stuff the shoes with crumpled newspaper and let them air dry overnight in front of a fan. If that doesn't work, try cleaning the shoes with a 1:1 mixture of denatured alcohol and water, see http://www.ehow.com/how_4883047_remove-mildew-shoes.html
Acid solutions such as diluted vinegar or diluted bleach are usually effective against mildew and its relatives, but also likely to ruin the shoes.
