I haven't been able to test it yet, but it seemed to work.

Together with Irvis hybrid, Petzl Back Flex form the best choice for all types of boots. Light and easy to put on.

A good addition to Petzl Irvis Hybrid crampons.

Thanks. Excellent and reliable delivery.

Great way to make my crampons span a full range of boots and shoes! As I am primarily a ski mountaineer using them with ski boots, I also like that they can configure one pair of crampons for many different boots. I have the two different backs and two different fronts and like that I can bring these along for other non-technical jaunts without having to buy another set.

Good way to make your petzl crampons fit on any footwear

Fix perfectly with Petzl Irvis LL.

Nice being able to put crampons on approach shoes.

Work as expected, Makes many petzl crampons fit boots without rear welts
