OS,
I cannot think of any current x-country skis that do not require some specialized boots. All my backcountry skis use three pin bindings. My boots are fine for walking though as they are essentially heavy duty backpacking boots with the specialized toe to fit the bindings.
It sounds like you are looking for some fairly archaic technology which might be found in used outdoor stores etc.
I would recommend you look at some of the new gear as it is far easier to ski on and the boots are not bad at all when off-ski.
I have both Karhu and Fisher skis.....a decade old, so even these are pretty primative compared to the new stuff, but I do not think I have seen regular boot skis ever.
