Testers were again awed by the freakish power this boot loads to the inside edge, providing meat-slicer precision in all turn shapes and snow conditions. Best suited for guys with slimmer calves, the X3's narrow cuff is its megawatt power plant. It tapers down to a close fit of the foot, but there's more room to be had if you need it, thanks to the Custom Shell's expandability. Notes: World Cup Advanced Shell Technology maintains a close match between shell and liner shape and the foot and leg for quick and powerful reaction to movements, Custom Shell technology's Kaprolene panels on medial and lateral side of the foot allow for 6 mm of custom width expansion, Backbone rear spine anchor system provides rigid fore-aft engagement, dual (dismantle) cuff adjustment offers maximum range of adjustment and bootfitting options.
