The K2 B.F.C. 90 is an excellent choice for the intermediate to advanced skier who has a medium to wide forefoot and leg shape. A Natural Stance is more upright to create a greater range of motion, less fatigue and more control over modern shaped skis with rocker. K2's Powerfuse Spyne has added reinforcements in a Y shape on the rear spine of the shell that adds more forward flex power and added rebound when you ramp up the speed. One of the greatest features on the B.F.C. 90 is the Hands Free Entry that is effortless to slide your foot in and out. If you want a very accommodating boot for wider feet and is easy to ski and put on, the K2 B.F.C. 90 is a perfect selection.
