I'm pretty unhappy with the design

I just climbed Mt Shasta in them trying to keep them on for as long as possible before switching to regular crampons. The fact that you absolutely can't use your risers on even moderately steep sections sucks a lot. I ended up doing hundreds of switchbacks on the icy slopes and it was very unpleasant. I would have saved lots of energy and time if I just took my skis off. So, I'm not sure what the purpose of these crampons is...

Required Gear for Steep Skintracks

Ski crampons should be required gear for any steep traversing skintrack. They greatly enhance security in such situations. The only drawback of the Fritschi design is that you have to exit the binding to attach the crampon, so best to figure you that you'll need the crampons before you're suddenly on steep terrain and have to do some tricky moves to exit and then reenter the binding. The other problem is finding a convenient way of carrying them in your pack, try threading some shock cord through the small holes in the crampon for an external attachment approach. If you have the most recent generation of Diamir bindings though, you might want to consider the newer Axion crampon, which can be affixed yet not deployed until you actually need it.

Find another option

These crampons suffer from a design flaw that renders them fairly useless. If your heel lift is engaged the teeth won't dig into the snow, because the crampon itself fits over the rail that connects the binding's toe piece and heel piece. Voile makes a ski crampon that attaches directly to the ski - a significantly better option. It's more expensive, but you won't be wasting your money.

Not designed for serious climbers

The downfall of the crampons if that they attach under the boot and rise and fall with your foot. This is fine on an easy grade, but any attempt on a moderate to steep grade your faced with difficulty. You are not able to set your risers up (because then the teeth will not penetrate the ground effectively) and therefore to climb at a steeper angle your body has to be in an awkward, crouched over, less secure bend that takes an unnecessary amount of energy. With that said, unless your sticking to easy flat terrain, consider another option or plan to custom alter them to work for more diverse backcountry terrain.

Requisite for the alps.

A necessity for steep skintracks ski touring in the Alps. The easiest way to carry them is to drill a small (3/16") hole and thread them with parachute cord, then clip them to the waistbelt of your back so they are easy to get to when you need them.
