Just heat moleded my Hyperlite Murry boots two days ago. Another option is to take you're boots to your local snowboard shop and use their heaters.
Remove you're footbed, put a hair dryer in the boots for about 10-15 minutes. Replace the footbed, then step into the boots, DO NOT tighten them up all the way, just snug them up. Make sure to stand in your riding stance for at least 5 minutes. It's recommended to keep the bindings on for about 15 minutes total while the foam totally cools. Then you're done. Super simple.
