I sir am on my fifth pair of ions and they are my boot of choice. I do not have them heat molded when new, I simply break them in by wearing them a few hours a day around the house, for about a week, and let the foots natural heat perfectly mold them to my foot. It is damn tight for the first few days, but the end results are dare I say perfection. The boot and I are one. find a pair of last years cheap and never look back.
