Pros: They make OK wheel chocks
Cons: They make horrible bindings
I created this account specifically to provide my review of KneeBinding. My hope is that I can help others to learn from my experience.
My KneeBinding's were given to me as part of a promotional service by KneeBinding's John Springer-Miller (JSM). This promotional service was intended to put KneeBinding's in public view by having industry professionals on them.
The KneeBinding has several design flaws that make the binding awkward at best, and outright dangerous in some situations.
1) The ramp angle of the binding is high. KneeBinding's CEO, John Springer-Miller, assured me that the ramp delta is within normal parameters, but I could not help shake the feeling that I was skiing on heels.
2) The binding is also very difficult to step into in cold weather. Again, the CEO assured me that there was nothing wrong here. Thankfully he was able to tell me the error of my ways, I have been stepping into the bindings improperly the whole time. I've been skiing for 29 years (since I was 2), 12 years racing, and 16 years as a professional. I'd like to think I know how to put skis on my feet.
3) Most seriously, these bindings are left foot right foot dependent. This presents two problems. First, I can't switch out my active edge without having to re-mount the bindings. Second, It's outright dangerous to wear the bindings on the wrong foot. Because of the binding's lateral release system, having the binding on the opposite foot will cause the skier to laterally release when loading the downhill ski.
As for my experience, I successfully had a complete tear of my ACL, a tear in my medial meniscus, and a fracture of my tibial plateau while skiing on KneeBindings. This after having no prior knee issues. Buyer beware.
