The Petzl Leopard FL are 10-point aluminium crampons weighing 330 g, built for snow approaches rather than technical ice or mixed climbing — aluminium is light but wears fast against rock and bare ice, so treat these as an approach and glacier-travel tool, not a mountaineering crampon for sustained front-pointing. The CORD-TEC link system connects the front and rear sections with a flexible cord instead of a rigid bar, which lets the crampon flex with a hiking boot's natural roll rather than fighting it underfoot.
Ten points give enough purchase for firm snow slopes and glacier approaches, and the design is sized for hiking boots rather than stiff mountaineering boots with a welt for step-in bindings. A carrying pouch is included, which matters given the sharp points and the fact that you'll likely be swapping between crampons and bare boots several times on the same day.
This suits spring or early-summer snow patches, glacier walk-ins and moderate névé on an approach — not steep ice, mixed terrain or long stretches of front-pointing, where a steel crampon holds up better.
