difference is plastic used. FTs are just a bit lighter than flexons, but flexons are light enough to not care about the weight while skiing(as most alpine boots are). Oh and the FT intuitions are fake. Well, they are intuitions, but only a fraction of the quality of intuitions you order off the intuition sight. Having good liners is important, and footbeds is super important. If you have intuitions w/o a fb, or liners with a flat footbed get good ones. I recommend SOLE footbeds. pm me with any questions about them.
