I've talked about this incident with a Jones sample but never publicized the photos. EZL's footprint is pretty small and it's been 3 years, so I'm not as worried about people getting the wrong idea any more. For the record, Nidecker Group / Jones took care of me (including at one point JJ himself lol), they fixed the issue in production before I even flagged it, and I still exclusively ride Jones / fka NOW bindings.
I was cruising around on a dope sunny January day at Mammoth. Pop a casual ollie cruising a blue groomer at decent speed, my rear foot goes all loopy on the landing, g into a controlled butt slide. Look down at my binding, I'm confused because my foot's still in the base tray and my ratchets are still in place, I tap the binding and realize my heelcup exploded around my boot. Had to one-foot my way down 1500+ ft of vert, SUPER lucky this didn't happen in consequential terrain.
You can see in the first photo the crack propagates off a cored out section of the heelcup. This was a sample for the first year of Hanger 3.0, so I'm not sure if this is was a shortcut specifically for samples or a design flaw they fixed. In any case, that section's filled in on the first year production model I got on warranty.
I can't upload video here, but I have a clip where I literally hinge the broken-off section of heelcup up and down like a lever, highback and all.
