Apply heat at the bottom of the insole's arch. Only heat it up for about 30 second. Bend it the desired way and amount (depending on whether you want higher or lower arch support). Hold it in that position until it cools down. It should not be too hot to touch. After heating/bending, place under cold water for a quick cool down. This will also retain its position.
