Heat moldable liners are boot liners designed to conform to the foot more than a standard liner would. The materials used in these liners react to your body heat to form to the your foot. With the exception on an Heat moldable liners will usually only add a small bit of conforming over other liners, with the exception of Intuition liners, but they will usually maintain that fit better over time.
How Do I Mold the Liner?
There are three methods you can use to mold your liners.
1. Let the natural body heat from your foot do it over time while on the slopes. The liner will usually mold after about 3 solid days of shredding.
2. Use a hair dryer on a low setting to heat up your boot, being careful not to melt any of the material. Then, wear the boot clamped on for 10-15 minutes. Repeat a few times.
3. Take it to a shop which has special boot heating assemblies to do it for you.
If you have an Intuition liner, the story is entirely different. Those liners will mold very specifically to your foot and are worth the time to actually dial it in correctly. We recommend you have Intuition liners custom fit at a ski shop. You will not regret it.
