Retrofitting Tech Binding Holes Into existing Boots

[G-spotter]

So let's say a guy wants to use skis to approach climbs but climb in mountain boots not ski boots.

Has anyone ever successfully retrofitted the holes for tech bindings into an existing non-ski boot? Are there cobblers that can do this? Like if one could get an old pair of Koflachs or something and then get a new sole put on that takes tech bindings for modern AT skis?

Seems like it might be cheaper than spending $1000 for the dead bird ski boots that purport to climb like climbing boots.

This question has been asked on the ski forums before, so maybe search there. Talk to Lars and Silas at CAST bindings.

I met a guy in the Alpental backcountry last year who had tech inserts in a pair of Koflachs that he used with a split board. Probably the weirdest setup I've ever seen. But it's definitely possible!

Yes, I would say talk to CAST. They do exactly that for alpine ski boots.

Year old thread... I know.

I have been going fast and heavy by wearing my ski boots (Sportiva Sideral 2.0) for long approaches, carrying my climbing boots. But it is heavy and makes for a cold change over (twice!). However, finding patches of good snow and good skiing is certainly better on the way out with a real ski, boot, and bindings.

For shorter approaches, Silvrettas continue to be the binding of choice for me. However, I have thought about making some boot soles that would attach to the ski boot like a crampon, and then have tech fittings to integrate with my touring skis.
