Work like a champ!
Have Freeride Pros on BD Voodoo skis / BD Method boots. They attach very easily and solidly to the binding. Fairly easy to deploy and retract using ski pole tips and a couple pushes/pulls with the basket - on the go. The cleats only extend a couple of cm below the skis when on the highest heel setting of the binding, so not a lot of bite going directly up a steep slope when heels are set high. But I have found that these crampons REALLY do the trick during traverses and generate great stability during kick turns. My only concern was that I got a 110 mm set only because my ski waist (88 mm) would not accommodate an 86 mm set. Once I got them I couldn't see how an 86 mm set would work for most adult folks as the cleat(when retracted) on an 86 mm pair seems would have dug into the bottom of my boot. Have about a 1/2 cm gape between the boot outer edge and the cleat. Don't know - just glad I got the wider ones.
