Camp USA Cassin states that its Blade Runner Alpine Crampon is the most versatile and technical ice crampon on the market for ice, mixed, and alpine climbs, and for good reason. It has an innovative heel slide that integrates the linking bar with the heel piece for better torsional rigidity, and it combines the power and stability of vertical frames with the precision and easy adjustment of horizontal frames. Made with Sandvik Nanoflex steel, the heel slide is incredibly strong for how thin it is, and it provides the right amount of flexibility throughout the crampon. Cassin made the front platform out of Cromoly steel to absorb impacts and maintain solid rigidity under your foot, and it reduces the flexibility and play that makes you feel insecure on technical terrain. The Blade Runner offers easy penetration on icy precipices and a superior hold even in ever changing conditions. You can switch the front points between dual and mono, centered or offset quickly and easily thanks to the hook and notch system. Semi automatic toe bails and anti balling plates give your boot a secure fit regardless of whether your boot has rigid toe lugs or not. And an asymmetric design follows the contours of your boot to ensure a precise fit that gives you the confidence you need to send successfully.
