theres alot of speculation going on in this thread. as someone who has ridden the original raichle/line version of this boot, kryptons, and full tilts/flexons, id like to clarify the differences.
the Kryptons and full tilts use the same design. the Krypton is the newer incarnation, and uses traditional buckles instead of the cable buckles found on the full tilts. This technology was all pioneered by raichle.
the Line Transfer was a different colored version of a previous Raichle boot. It does indeer use the same kind of 3 piece shell/tongue design of the first two boots, but insead of having the standard fixed-lip rear stop, they have an adjustable bracket on the back. this allows you to do a number of things. for one, it allows you to set the position of the forward lean on the fly. everything from fully unlocked (beyond upright "walk" mode) to full on race lean can be set. additionally, you can lock the upper cuff in place in the boots at any one of these stops, like instantly being able to switch from plugged boots to full flexing ones.
The amplid boot is a reincarnation of the line/raichle boot. Its obviously been reworked to improve the quality, as the first versions were sold as fairly low end boots with horrible buckles, crappy liners, and rigid footboards.
im pumped for it. it skied well back then, and with the improvements, im definitely going to be looking at picking some up.
