No. No. and no.
Full tilt is part of the K2 trademark. They use the old Raichle molds. Dalbello is partnered with Elan and is manufactured out of Italy with their own molds. Yes, they have a 3 piece concept that they share but thats it.
I personally have dalbellos. I hated the original liner and it broke down in about a month and a half of skiing for me. The intuition liners (full tilt has something similar) are money. I agree with liking the dalbello buckle system more.
Don't buy a boot without trying it on. If its money you are worried about, drive the hour to the shop to try them, it'll be worth it if thats what you end up getting.
LOL DONT LISTEN TO HIM!!!
k2 owns fulltilt but i have no clue about dalbello, and dalbello is a complete differnt fit besides the fact it has 3 buckles!
