Thermo Molding (Read 452 times)

I just bought another pair of my usual insoles, SofSole, and read the instructions. They said to heat the insole in the over, put it in the shoe, stand in the shoe, and your insole is molded to your foot. I have done this with ski boots but never with running shoe insoles. I am worried that if I do this, some of the supportive properties which I love will be lost or changed. Has anyone ever done this, and if so, how did you like it? Would you do it again? etc...
