The Alpinist Pro optimizes the benchmark Alpinist crampons for the most technical alpine terrain. Using much of the same technology and innovative design as the Blade Runner crampons, the Alpinist ensures a precise fit with modern boots and extra rigidity in the connection between the heel and toe platforms. This is due to the unique heel slide that integrates the micro-adjustable linking bar with the heel piece for better torsional rigidity. Constructed entirely from chromoly steel for the best energy absorption anywhere the crampons might be stressed. The elimination of connection joints leaves little room for play and reduces much of the flex that can make crampons seem less secure on technical terrain. The sophisticated geometry of the integrated ice points interacts with the secondary points for superior hold in steep, hard snow and vertical ice. The Alpinist Pro is delivered standard with both automatic and semi-auto toe bails for optimal compatibility with boots and conditions. The micro-adjustable linking bar allows fine-tuning of the length. The front bail can be set in three positions for optimally positioning the front points and the heel bail can be set in two positions for different size heel lasts. The heel bail also has three height settings for the most secure attachment with the boot. Dynamic anti-balling plates use a unique design and elastic material to prevent snow build-up underfoot.
