CASSIN BLADE RUNNER - Crampons size 1

Revolutionary Design for Technical Ice and Alpine Climbing

The CASSIN BLADE RUNNER represents a breakthrough in crampon engineering, specifically designed for climbers demanding maximum performance on vertical ice, mixed rock-ice terrain, and alpine mountaineering. This size 1 model integrates a patented heel slide mechanism that connects the linking bar directly to the heel piece, eliminating play and flex while maintaining the responsiveness needed for modern boot geometry with extreme rocker profiles.

Advanced Material Technology and Frame Construction

The entire heel slide assembly is forged from Sandvik Nanoflex® proprietary steel—a patented alloy proven 70% stronger and 20% harder than standard stainless steel. This innovation allows frame thickness reduction to just 1.8 mm while increasing structural rigidity and providing precise longitudinal flex. The front platform uses chromoly steel alloy for impact absorption and consistent underfoot rigidity during technical sequences. Elimination of connection joints reduces play that causes insecurity on steep terrain.

Precision Front Point System and Modular Configuration

The sophisticated geometry of the front points interacts with secondary points on the main frame for reliable penetration and superior hold even in unstable conditions. The hook and notch system makes switching between dual-point and mono-point configurations simple, with options for centered or offset positioning based on climbing style and boot preference. Optional beveled snow points with precise spacing maximize purchase in hard alpine snow, converting the BLADE RUNNER into a true all-mountain tool.

Secure Fit and Anti-Slip Innovation

Dual bail compatibility ships standard with both automatic front toe bails for rigid-lugged boots and semi-automatic toe bails for boots without rigid lugs. A new heel bail with three height settings ensures micro-adjustable fit across boot models. The micro-adjustable linking bar allows fine-tuning of overall length for optimal boot contact. New dynamic anti-balling plates are specifically engineered to prevent snow buildup—a critical advantage in wet conditions or spring climbing. The asymmetric design follows modern boot contours for a secure, precise foothold.

Included Accessories and Intended Use

The CASSIN BLADE RUNNER size 1 arrives pre-equipped with mono-points and automatic toe bails, plus two extra front point sets and semi-auto toe bail options included in the package. An adjustable fold-over carrying case with lashing straps provides protected transport and field accessibility. Ideal for ice climbers, mixed terrain mountaineers, alpinists, and guides who demand the most technical crampon on the market for vertical ice routes, ice climbing areas, alpine expeditions, rescue operations, and extreme terrain where precision, security, and lightweight performance are non-negotiable.
