The potential for this new heel insert to not work with boot brands other than Dynafit was a source of early criticism by boot manufacturers. It is possible the number of boots that exhibit problems working correctly with the Beast is larger than this notice indicates, but these incompatiblities can serve as examples of things to look for with other boot models.
Power Insert Incompatibility
All of the new generation of Black Diamond AT boots will not work with the heel plate for the beast. As you can see from the picture below, Black Diamond revised how the standard heel insert for tech bindings is shaped, and thus the alignment pins don’t mate properly. AT boots from Black Diamond made prior to 2013 may work with the Beast heel plate. I have not confirmed this, but they have a standard heel insert pattern, so theoretically they do.
Affected Black Diamond AT boots:
- Factor with Tech Pad
- Shiva with Tech Pad
Toe release in “locked” tour mode
Another issue occurs at the toe in touring mode. The Beast toe has a lock out mode, but the jaws can still open if the boot shell contacts the toe unit when the boot pivots beyond approximately 60°. This could happen in a forward fall, or during a kick turn.
It is a known issue with three boot models:
Atomic’s Waymaker 110,
K2′s Pinnacle 130,
and Salomon’s Quest 120.
Even though the incompatibility is due to the shape of the shell on these boots, Dynafit is modifying the shape of the piece on their toe to minimize this potential pre-release in tour mode.
This will alleviate the issue with the K2 and Atomic touring boots, but the shape of the Salomon boot may still cause the toe to release in tour mode if the Quest pivots too far forward. As with all new technology, caveat emptor.
