Tour Nanotech Semi Automatic Crampons

The lightest steel crampons in the world! Sandvik NanoflexR Steel uses nanotechnology to create a superior metal that is 30% stronger and 20% harder than traditional chromoly steel thereby allowing us to use a thinner cross section 1.8mm that results in a crampon that is not only lighter, but stronger, more durable and stainless by design. The thinner cross section also creates sharper, thinner points that penetrate hard snow with ease. The semi automatic binding is compatible with most mountaineering boots. For telemark or AT boots, use the Tour Nanotech Auto with automatic bindings. Note: Due to the decreased size of the front platform, we recommend this crampon for boots up to size US 10.5. For larger boots, we recommend the XLC 470.
