We receive regular reports about failed boot heel tech fittings. Thus, this post needs to be better indexed and known so we brought it to the top today, with edits and additions so it indexes better.
Regarding boot heel fittings for tech bindings, they are indeed sometimes too weak for aggressive skiing with big boots and skis. On the other hand, don’t panic, the vast majority of backcountry skiers do fine with existing versions of boot heel tech fittings. Nonetheless, overall what we really need is tech 2.0 or at least something like the tech fitting that Dynafit will be providing with their Beast binding (The Beast fitting will work with any tech binding with some attention to clearance during release and possibly a slight modification. I worked on this a bit yesterday with our Beast test fittings and they looked good when paired with Dynafit Vertical and Radical heels.)
