Silvretta bindings on mini alpine skis. I assume the were approach skis. The skis will fit in a skin track.
The bindings will accept plastic and leather mountaineering boot, ski boots, and even telemark boots. My size 10 Koflach boots fit with adjustability both up and down.
They are in good working order though I won't vouch for their releasability. If you want ski get a modern paur of alpine touring bindings.
