I also have (had) the Dalbello Kryptons and tried for three years to get them to fit with various inserts, pads, etc but it was a constant struggle and a lot of pain. Appreciate the validation that these are tough for narrow feet with high arches & excited to explore the suggestions provided here.
Thanks for the info! Mine is the Dalbello Krypton. I have the same issues. I also think that the three buckle system is hitting the exact top of my high arch, which causes some issues. I need to move to a stiffer boot with four buckles, I think.... I will try the Technicas
