Maybe something like the BD Seeker or Push, Scarpa T2. They are not soft telemark boots but, also not in the upper end of flex ratings either. If you go to a NTN binding like this you will lose a lot of flex all together. The boots that are compatible with this binding do away with the duck bill of traditional telemark boots. A lot of the flex in the boot comes from this duck bill, its a different way of telemark skiing. Maybe an updated binding like the SwitchBack could give you some more energy as well. I am going off information from Casey's experience with them so I will ask him to chime in when he gets to work on Tuesday, I am definitely an alpine skier.
