Replying to Intuitions

should i heat mold them or just suffer for like 3 days and let them pack out au naturale? i have a homie who didnt mold his intuition skate liners and says theyre like flawless on his feet. i have another homie who said his ski liners are too packed after heat molding them. thoughts? i ski a lot so ive never heat molded liners before these, but other liners are also not made of rocks pre mold. also general liner discourse is welcome in here im a tech nerd
