Black Diamond Contact Strap Crampon

I strapped these onto a pair of Lowa Banff's and they worked great. Once you get them fitted, which took about five minutes, they were on and off within a few seconds and never had to readjust them once attached. I was completely confident while I was ascending a steep chute which is a good thing because you don't want to have to focus on gear at that point. I used these while climbing the Mt. Whitney Mountaineers Route on snow which ranged from hard frozen early morning crust to soft afternoon crud and I never had a problem or any difficulties. The ABS plates come with them and already installed and they worked fine. They are very well made and durable and I can see myself using these for years to come.
**I would only use these with backpacking boots, I tried them on a pair of Lowa Renegade hikers and they don't work.**

These were my first pair of crampons and I loved them. I used them mainly for ski mountaineering but have done plain snow travel on them as well. They fit on alpine and AT ski boots as well as mountaineering boots just fine. In addition to moderate slopes, they actually handle steep snow very well. I tend to just keep them for the steeps and skin on the shallow. I have used these for front-pointing up 45-50 degree couloirs and they performed flawlessly.

A solid 10-point. I use these for ski-mountaineering in the cascades, as well as general alpine climbing. If you're going vertical you'll likely want something a little beefier, but nothing beats the security of the strap on crampon for glacier and snow travel (I've used these up to about 55 degrees with no trouble). I also found that these fit perfectly on my Dynafit Zzeus, and they also fit nicely inside the BD Crampon bag.

I picked these up for my recent splitboard trip up Mt Whitney in the Eastern Sierras. I had never used crampons before but I was told to get some in my kit. They worked great on my board soft boots. I wear a size 11.5 in Salomon Malamute's and these fit fine all though just barely so careful if you have larger feet. They are light compact and will last for years in steel

wasn't sure how they would play out on snowboard boots but they worked very well on the steeps at tuckermans and the various chutes at mt. washington. some parts are definitely in the 40 degree slopes and one in particular has to be near 50 degrees. its not the gnarly high sierra slot but it certainly made me feel far more comfortable than i have in the past. go get the goods.
