They're a bit muddy and it's been suggested I just throw them in the wash.
I am a bit weirded out by this idea seeing as the trainer soles have god-knows-what all over them, there is all sorts over the pavements as well as the mud on them.
I know I could run a bleach wash afterward and I know the purpose of the machine is to get dirty things clean again.
So do you wash your trainers etc in the machine?
