CC Ski boots and bindings

I am trying to find the proper boots to fit the Salomon bindings for cross country skis shown in the links below. I cannot determine the type of binding based on internet research. The skis are pretty old, I would guess 20 years? Original bindings i believe. thanks for any help.

I’m pretty sure those are the original Salomon SNS bindings, they haven’t been made in a while and the newer bindings and boots aren’t compatible. For finding new boots look on eBay or you may have to buy new bindings and boots.

Thanks Telemark. i will look at ebay first.
