I've had good luck with the footprint hi profile kingfoam flat insoles (7mm). All their others including the ones you bake, I've hated, but the flat ones I've liked. My biggest problem has been what they call customer service.
I asked a question or responded to someone on social media prior to getting the flat insoles about my bad luck with the "nicer" insoles being rock hard and never softening up, and their social guy's solution was to basically tell me I suck and must not be using them right, not that I could have a defective product. It's a great way to win over customers (and yet my dumbass did buy another pair of insoles from them after that).
