The webbing strap loops from one ankle, by way of the entrance cup, again to the opposite ankle, and throughout the entrance of the boot’s tongue, earlier than slipping by way of a buckle that holds it in place. So long as the webbing strap is pulled tight, the crampon stays on fairly securely.

For bigger sizes, you may substitute the flex leaf spring with a longer flex bar, additionally offered by Grivel, which is appropriate with a lot of their different crampons fashions too. To suit the crampons, you develop or shorten the size of the flex bar, utilizing a easy spring-loaded pin adjustment system in order that the entrance and rear heel cups match snugly over the ends of your boots. That’s all there’s to it.
