The Grivel G10 are C1 rated classic universal crampons, ideal for general winter walking use. Created to be streamlined in design, with a semi-rigid, torsional design for holding, these crampons are perfect for ski touring, trekking, or for women & children, whose small boots don't require many points underneath them. The New Classic binding system is simple, reliable, quick & easy, making it ideal for first time users. Both the front & rear plastic harnesses are hinged from their respective retention posts & may be 'opened' to faciliate attachment to the boot, then closed securely once the boot is inside.
