I have a pair but can't tell you much about them. I suppose they are a bit different in that they have 3 rather than 4 buckles, but not sure of the benefit of this. They hurt me a lot when I first got them, but have had them punched out a few times and don't really hurt now (especially as I've improved my skiing since I got them as well). Don't really know what else to say.
No particular reason as such, other than to gauge pros / con before buying.
Have tried various models of approx same specs and they do feel the most comfortable.
Thanks for yr reply
