IMO too many moving parts, not an innovation.
It amuses me how easily people uses the word innovation. Innovation would have been if a new material (may be something like D3O foam)being used.
Too many moving parts to protect against an object in a very thigh motion is never a good thing.
And double wrapping legs could affect blood circulation, but that's just my point of view.
I'm not sure these would be for me, but you can't argue that they're not in some way innovative compared to whats out there.
It amuses me that people struggle with the definition of innovation.
P.S The internal combustion engine had a few parts more than what it replaced, it seems to have gone down ok
