The only reason why clothes get staticky in the dryer is because of the heat. If you run the dryer for 10-20min after drying with no heat they'll come out without a trace of static.

Ive stopped using softener and dryer sheets a while ago; just detergent and for the first load of the week (usually towels) a short cycle with vinegar to clear up any mineral deposits left by my horribly bad hard water.
