What's territying about the new boots?
Walk mode. Yes. God help me. Is there a real reason I shouldn't get that, as I asked above? Explain please. If the only reason I shouldn't get them is because you're more experienced than I and you don't use them, that's not a solid enough reason to me. I've read that in the past, the tolerances for the walk mode were not very sound and that walk mode compromises the flex of a fixed cuff. I'm asking if that's true, and if it's true to the extent that I'll be so disappointed with the ski performance of walk mode boots.
You're questions are unanswerable because they are so general. Reading between the lines, the walk mode boots you were considering were probably garbage. Basically a rental or box store boot.
Certainly there are good boots available that have a walk mode. If walking is important find an At boot with walk mode and a partly rubber sole.
You're in a different position than seg above who wants a walk mode. For one thing she hikes to ski. Second, she's not going to get a boot that's way too big or a glorified rental boot that has a walk mode.
Boots are the achilles heel of the ski industry. It's difficult for most to get one and make it fit properly. Easiest immediate solution which most do is to get one too big. If you ski 5 days per year that solution might work for three years. It'll never have been good and could be very poor but it worked.
