Extremely technical crampons and monocagous evolution of the Alpinist Pro model. Alpinist Tech is ideal for ice falls and mixed climbing, it is characterised by lightness, substance and precision. The T-shaped front prongs ensure optimal penetration into the most compact ice and provides grip in delicate situations. It is supported by the classically shaped secondary front prongs that provide grip in hard snow and stability on complex ice without disturbing rock climbing. Three vertical additional prongs (one on the heel and two on the front) ensure maximum stability even on cauliflower formations and ice lentils. Alpinist Tech shies no comparison thanks to its lateral and central strength and asymmetrical shape; it becomes an integral part of the shoe. The connecting bar has a double row of holes, which, together with the lever at the rear with three positioning options, allows an extremely precise, stable and secure adjustment. The durable anti-stud plates ensure effective snow repelling thanks to the design and spring back of the elastic material and are automatically included. You can also go from an automatic to a semi-automatic binding thanks to the ironing code. 2453C and the automatic/semi-automatic system code. 2450C (not included)
