 The aim was to reduce the amount of time it took to mount crampons to boots, and to simplify the process, as well as making the combination of boot and crampon lighter.Another advantage is that the system removes straps and bails from the front of the boot reducing the risk of snagging these in use.One boot designed to use the GSB system was the (now discontinued) Scarpa Mirage GTX, a Gore-Tex lined 3-4 season mountaineering boot.
