The Blue Ice Harfang Tech Crampon, a patented design, features a central textile strap connecting front and back sections, allowing custom positioning based on boot geometry and use. It accommodates a wide range of boot sizes, with a flexible strap reducing bulk and enhancing precision and comfort. Interchangeable front-toe bails enable easy fitting to boots with a heel welt, including a compact full auto and semi-auto system. The modular front spikes can be configured as single or double points, with adjustable length, making these crampons versatile for various challenging routes, from snow couloirs to ice climbing.
