The thing is to find a shop that will demo Kryptons, put in the Thermoflex liner from the Flexons and one run should tell, or at least give a good indication, if these are going to work better. In the meantime, it's good to hear from other Flexon holdouts, it's hard to let go of a near perfect thing. I ran into a patroller last year who let his go and wasn't real happy about it. For me fit & comfort trumps performance, and I figure that if they worked for all those champion free skiers (not to mention World Cup racers back when) then I can bash them around. I just use the stock tongues, I tighten up the top buckle when I want to go fast. With my skinny feet, I went through ten boots in ten years, foam, silicone, you name it, and have been happily skiing Flexons for the last ten. But I'll try the Krips, Phil, I promise- especially now that they have ditched the annonymous black for a nice electric green-
In the meantime it's good to know that the design lives, so we can get parts if needed, although I have a new, in the box, Kastle version stashed to replace my puke yellow 20th anniversary models...
Upper Cuff: Flexon, 12" Krypton, 11.5"
45 deg from heel pocket: Flexon, 16" Krypton 15.5"
Forefoot: Flexon, 11.5" Krypton 11.25"
In all three measurable points, the Krypton was smaller, hence lower volume. What people were feeling that the Krypton was a "higher volume" boot was the origonal stock liner.
