Designed to increase lateral response to suit modern ski technique and produce a pressure-point free fit, the Firearrow F2W has a three-buckle shell design with a 45-degree closure system designed to lock in the heel, get rid of pressure points and offer a roomier toe box. EDT technology adds a carbon fiber bootboard attached directly to the shell for more force with less energy—measured by Nordica’s Dynamic Performance Code, which evaluates stiffness, progression and rebound.
