Black Diamond's Factor 130 Boot is a responsive and stiff boot for skiers who require power and control. It is an award-winning alpine boot, and it also has a more flexible walk-mode for easy hiking. When in ski-mode, the boot locks into place for plenty of security. Originally designed in 2008, this version of the Factor 130 has a new liner for more warmth and a better fit than older models. It is stiffer than the Factor 110 for even more control and power. Additional features of the Factor 130 Boot include a plastic liner tongue, four buckles and BD Alpine Sole Blocks. The liner tongue ensures evenly distributed flex. A Power Fit Liner is made with thermoformable technology for a perfect custom fit. A wide power strap gives an even more secure and customizable fit. Articulating foot zones increase comfort at the body's natural flex points. An aerogel-insulated strobel base also ensures all-day comfort. The Factor 130 is an ideal boot for advanced and fast skiers who want a boot they can wear all day.
