Roll up some newspaper and stick it in your shoes... remove the insole so it can dry out on it's own and it is always good to have spares as a cycle these to keep them fresher.

The newspaper will suck all the moisture out of your shoes overnight and can be re-used endlessly.

When it gets wet and cold I wear my touring shoes and switch the insole to a felt pack as even if they get damp my feet stay warmer... these shoes are also sealed from the bottom so water does not get into them from that direction and with shoe covers I am golden.
