My personal experience is that I find trail runners much more stable than boots. However, while I do some off trail hiking, I avoid talus (more concern for my dog than for myself). Low gaiters are a good thing to have to keep gunk out of your shoes, to say nothing of keeping mosquitoes from biting through your sock tops.
It might help to know that Wind River guidebook author Nancy Pallister wears a crampon-compatible low cut shoe, even for climbing. And there are tons of streams and bogs to cross. Per Nancy: "Your feet will get wet in the Winds." Might as well have a fast-drying shoe!
