The new Zero G Peak Carbon, from Tecnica, is really an engineering marvel. The boot weighs in at 990g, at 26.5, and is incredibly efficient for touring with 75 degrees in range of motion. Tecnica has done an awesome job building a boot that performs and fits well for a sub 1000g ski boot. Even with this ultra-lightweight construction, the Zero G Peak Carbon can still steer a lightweight ski, keeping you confident on tricky descents. The carbon cuff is responsive and the overlapping shell allows energy to be sent to your skis efficiently. This is not a boot built to drive anything aside from lightweight touring skis, it's a specialized boot built for skiers who care about a lightweight Alpine Touring setup.
