About 25 years ago I rented "adaptor bindings" from a shop (since gone out of business) specializing in cross-country skiing. The adaptors would clip onto my ordinary downhill ski bindings, and my ordinary downhill boots would clip onto them. That is, they would go between existing DH binding and existing DH boot. They would have three settings:
- Hinged toe and free heel, for XC-style ski walking.
- Hinged toe and free, raised heel, for touring-style ski climbing.
(I also rented climbing skins as a separate pair of items.)
- Clamped toe and heel, for descents.
My question is in parts:
- What is the correct name for such bindings?
- Do they still exist?
- Where can I get them?
I have asked a few folks but the usual response is along the lines of "that's not the best solution". Of course, I know it's not an optimal means for Alpine touring or ski mountaineering, but given that I'm unlikely to do anything but occasional, beginner-style, Alpine touring, I think it is a very economical solution.
I'm assuming that getting ordinary AT bindings and swapping them in and out with my ordinary DH bindings is not practical or advisable. (Too much unscrewing and re-screwing weakening the skis.) Maybe I'm wrong.
