What is the best way to dry out my rugby boots before tomorrows practice?

On the radiators.

I always dry my football shoes by stuffing them with (old) newspapers, then putting them on the radiator or in the sun.

Light them on fire.

microwave or hair dryer

dont put them in front of a fire, itll melt the plastic.

like vin, i stick newspaper and baking soda in them, and put them on a heater/vent/in the sun.

Put some kind of powder that will absorb most of the moisture. Then place them in a warm (not hot) place.
