Oh dear. I am not a fan of any of the heat moldable boots, no matter what the hype is. They're a gimmick that allows the manufacturer to make the boots cheaply yet sell them at a premium under the guise of "new technology." Pro shops love them because the markup on those boots is huge, so of course they're going to push them more than the traditional Harlicks, Klingbeils, or SP Teris. (Last I checked, pro shops make about $200 for a pair of high-end Jacksons yet only about $50 for traditional brands. Gee--what ones are they going to give people the good sales pitch on?? Hmmm?) Plastic will never mold to your feet like leather no matter what they say. And even if they mold when you're standing still, they become solid again and you need not only front-to-back ankle flexibility, but a little lateral ankle flex as well. And they smell. I went through the gamut of these boots from Risport to Jackson, all of which I hated, after wearing Harlick customs for years. I thought I could get off cheap because at the time I didn't have the money for another pair of Harlicks and the guy at the pro shop sounded oh-so-knowledgable and nice. What a sales pitch he gave me! Well, I ended up going through more dreadful skates and spending more money than if I just had gotten the Harlicks to begin with. These days I use custom Klingbeils--although I'm still a fan of Harlick and SP Teri. Yes, everyone's feet are different and different brands work better for some skaters, but I am convinced that all-leather custom boots are the way to go. This way, I can get the strength I want (not very strong) in a fit that works for me. What I like about Klingbeil is that I can just go to the factory and they'll make any adjustment I need. (Yes, I do realize that this won't work for people who aren't in the Northeast, but the service can't be beat, even if you have to send them in.)
So for those who are loathing their Jacksons, Edeas, Risports, Grafs, and the like, you may want to consider getting a custom Harlick, SP Teri, or Klingbeil. The higher initial price will be more than worth it because it will save you headaches and money later on.
