I mean is there any advantage in armor by tying them so high or is it just for the looks? Were metal plates tied to the shins with them?

I assume you're talking about this kind of "gladiator sandal." That image has come from a combination of caligae, as worn by roman soldiers, and puttees. Footwrappings that wind up the legs are a common motif in depictions of soldiers in the past, which colors our ideas of what ancient soldiers would wear. Puttees, which are long strips of cloth that wrap around the ankle and calf, were actually worn at least as recently as WWII.
In short, there's little real advantage to boots with leather that winds so high up the leg. I've never heard of armor being tied to the legs at all, either.
Above all else, though, remember this: Rome's history spans over a thousand years, and so there are few definitive answers about what was or wasn't "in Roman [times/culture/philosophy/government]."
Just for funsies, here's a preserved caliga from egypt.
As a follow up question: Did they even wear the kind of sandals that were tied high that OP mentions, or is that something we've gotten from the movies?
