Tech Boot Repair

The CAST Tech interface is designed only for skinning -- unclear if it has the contours to allow for a release from a Tech binding while skiing?

And to remove the damaged interface from your boots, you would need to slice open the plastic that encompasses the Tech interface (i.e., as opposed to merely peeling back rubber as was previously suggested).
Then you would need to find a replacement interface that has exactly the same pattern/link between the two dimples.
And finally come up with a way to seal up the plastic strong enough to withstand all the forces while skinning and skiing.
(This final element was the problem with a bad batch of Dynafit Zzero4 boots as previously referenced in this thread: the interface was fine, but the plastic could crack around the interface.)

oh rainy day....

Here's what a CAST thingy looks like.
That is not a ski boot, it's an old Scarpa Omega, I don't know anything at all about skiing. I hear it's fun having those 2 sticks, one on each foot!

If you got them in PDX then it was probably from one of these shops-

The Mountain Shop
Oregon Mountain Community
US Outdoor Store

Or Evo Portland

Sorry I missed your post when it first came out! I had exactly the same experience with my Spectres! At first I thought it was due to my bindings (Plum Guide). The insert on one boot is all ovalled out and I think it was due to not having the pin and boot properly aligned when I put them on. It allowed the boot to click around a bit when I skied, and I could not STAND it!

Long story short- I went through all the same channels you did with no luck. I ended up buying an identical pair of boots used. I now have three good shells, four good liners, and a boatful of extra buckles, etc.

Somewhere I heard Sportiva does not use "official" Dynafit inserts. Maybe the metal is crap or something like that.

As for that "repair" scheme, I'm not sure I'd trust it. The whole tech binding scheme is based on those tiny pins, and I think it's super important that the fitting is molded into the shell. I don't know why such soft metal is used for the insert. Not a good place to save fractions of an ounce in my mind.

Anyone have the answer on fixing these, please? Haven't taken to the phone yet; and whadyaknow - it's a Spectre with a "sorry it's your fault" response from Sportiva (and a no, we can't fix them)."

Jeezum. Hardly used and I'm not that dumb stepping in. Clues and failure happened in the course of one day; could tell something was clicking on one side and finally saw that my toe was pressuring through the binding past the wing; no sign of it previously.
