They actually sell a little shoe hanger for your dryer door so they don't tumble around like a bunch of rocks in there.

I personally don't wash mine cause I'm rolling around underneath vehicles every weekend lol, whats the point..

 

I also scrub the nasty spots with dawn or similar and throw them in on cool or warm wash....I have dried them but usually I just prop them up in front of a fan overnight and they're good and dry the next morning and ready to wear. Unlace them before you wash them so the tongue doesn't fall in and keep some of the detergent from getting inside.

 

Never washed my shoes...always wear flip flops!! just squirt them with the hose.
