The webbing strap loops from one ankle, by means of the entrance cup, again to the opposite ankle, and throughout the entrance of the boot’s tongue, earlier than slipping by means of a buckle that holds it in place. As lengthy because the webbing strap is pulled tight, the crampon stays on fairly securely. It’s a quite simple attachment system that works with virtually all boots and is extraordinarily sturdy regardless of intense abuse.

Sizing

The G1’s match boots which are a males’s dimension 36 to 44 EU (approx 5 US to 10.5 US). For bigger sizes, you may exchange the flex leaf spring with a longer flex bar, additionally offered by Grivel, which is suitable with a lot of their different crampons fashions too. To match the crampons, you broaden 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.

Anti-bott (Anti-balling plates)

The G1 Crampons include anti-balling plates that forestall snow, usually moist or damp snow, from sticking to the underside of the crampon. This is hazardous when it happens as a result of prevents the crampon tooth from getting buy – it’s quite a bit like making an attempt to stroll on high of bowling balls. These plates are merely items of sentimental plastic riveted to the underside of the crampon with versatile facilities formed like little domes. This creates some flex within the anti-balling plates if you stroll, which is sufficient to dislodge any ice or snow that has caught to the underside of the crampons.

They are designed for strolling on reasonably angled ice and densely packed snow, together with glacier journey, the place the additional chunk offered by their 3 cm carbon metal tooth gives aggressive traction and prevents high-consequence, uncontrolled slides. They have a common binding suitable with all boot sorts and anti-bott (anti-balling plates) to forestall snow from sticking and clumping beneath.
