These are excellently lightweight, and pretty compact. The cord connecting front and back parts is a good innovation, I think. Maybe would be vulnerable if you walk on rocks a lot...but a metal bar is, too, and this might even be easier to replace or repair, if necessary. There is a some adjustability in the fit, but I was unable to get a really rock solid fit. Good enough for low angle snow, anyway, and these are not intended for front pointing on ice, of course. I don't care much for the plastic harness components. They make the crampons a lot bulkier for packing than they otherwise would be, and don't conform very well to the shape of my boot. And I sort of have the feeling that they will wear out and break or tear eventually...although have not seen any evidence of that. Maybe Petzl has figured out that there are good reasons to do it this way, but I believe I would rather just have rings and criss cross straps, like my ancient Salewa aluminum crampons. Happy to have these, those, as they are way easier to carry than my steel ice-climbing crampons.
