It was time to finally bail on my Rambo's sadly so after much research I bought these and have been pretty much totally psyched about them. Very user friendly, easy to use, performance is great, I could go into technical detail but I'm not paid for this so I'll just say my man borrowed them to climb Denali (ten years after i climbed it) and he loved them as well. Ice, alpine, they are great.

as a female with a narrow heel, finding a crampon that stays on my boots are key, and finding a crampon that prevents balling and added weight is even more important! these grivels do all that and remain sharp and spikey. I highly recommend them, easy to put on even with thick mittens on, easy to adjust and they keep their edge. I would recommend getting a crampon bag whe buying these or any crampons to keep them safe in your pack

These are great. Easy to put on and adjust, they have great hold, and are an all around versatile and high quality crampon. I have size 13 boot (Asolo brand, US size) and they just fit when using a nut+bolt to hold the bar. Anyone w/bigger feet will need to buy the extension bar.

Far better and more versitile than standard 10 point "general mountaineering" crampons. More agressive secondary points allow for more secure and efficient front pointing giving you more confidence on steep ice. New-Matic and New-Classic are great options for binding systems. New-Matic still works without substantial heel welts.

Performs very well on alpine routes and soft waterfall ice. The horizontal front points dont shear threw snow like vertical ones, the trade off is that they dont penetrate hard ice well and are just ok on hard mixed stuff. Bottom line: the best out there for alpine. Hard water ice and mixed, look elswhere.

This crampon is great! Glaicers, snowslopes, ice...this takes it all. It is easy to adjust with its macro and mirco adjustments and once it's on the boot, it stays on. The antibot plates keep the snow off the bottoms so you always have points making contact with snow/ice. You can even ice climb in them, even with the horizontal front points. They look pretty sweet too.
