did the army switch from caligae in 1st cent?

[richsc]

I just got a book on Roman costume recommended by Hibernicus/Sean Richards (many thanks!) and was reading in the 'footware/caligae' section that C. van driel Murray says that the army started switching from caligae to closed boots at the end of the 1st century. One thing she mentions is the lack of caligae finds at Vindolanda, where they find everything else but.<br>
In the cold climates like Britain it would seem a very practical switch, but as Matt likes to point out, the Romans werent' necessarily bothered by practicalities.<br>
Does anyone have any updates on the footware thinking? I"m about to make a pair of caligae, and was wondering if we should have a 'late 1st century enclosed army boot' in our events.?? <p>Aulus<br>
