A powerful old school boot that combines world cup race design with a more all mountain build, the Tecnica Attiva Diablo Pro is a stiff model made to charge hard. The boots 100 flex is a nice stiffer flex for a hard charging lady ripper while a comfy liner helps with fit, especially in the lower calf. If you are looking for a great deal on an older model boot that still rips, the Tecnica Attiva Diablo Pro is a great choice. *note, new out of box*
