Curing spraypaint, What cures paint faster/better?

So the paint I applied to a pair of shoes, Krylon Fusion, is still a little tacky in some areas where I may have sprayed it on a little thicker than in other areas which are not sticky. What is the best method for assisting the curing process? Would some time in a low heated oven work faster, or would a good fan blowing on it work best?

If the paint cures by evaporation then the fan would seem to work the best, otherwise if it's a chemical reaction, then the heat sounds the best. I can't do both at once.

Hopefully the areas that are still sticky weren't vinyl....If they are they may NEVER dry.

I sometimes put the items in my bathroom with the vent and heat turned on.
If your bathroom does not have a heater, then a small portable heater set on low will do the trick
