DH let DS1 wear his lovely flashing trainers to the beach. They no longer flash, and now smell terrible as he would have gone paddling in them. Don't know what was wrong with wellies or crocs, but that's another story!
Anyway, in a last ditch attempt to save them, they are now in the washing machine. What is the best way to dry them bearing in mind we have no sun here today, and haven't got the heating on. I find if they dry slowly they stay smelly.
