“likely covered their foot with some sort of fabric before adding the sandal.”
That is interesting-sounds like they put a sock made of fabric on their foot before they put on their sandal-duh-apparently 1500 years ago people already put on socks in cold weather-and maybe that person left their closed shoes/boots at home, or didn’t have a pair...
Or maybe the person lost their foot.....................
If he was wearing socks with sandals he was probably a German tourist.
