I think those are Altai hoks (the longer skis) and they have a skin glued into the base, iirc.
I have been trekking around on skis like that since garmont made the beluga back in tge late 90s. They are perfect for low angle pow and getting in a few quick laps in the backyard.
I have the OAC version (160 length, 110 underfoot) now and use them almost daily in winter for dog “walking”. So much fun.
