Caligae Construction

[Martin Moser]

I have a related question about caligea; are their any finds with extra heel pieces added into the layers making the sole, so that the heel is taller? My first pair compressed far more in the heel than the rest of the foot and it messes with my calf muscles.
Some stacked leather medieval pattens made in the same way as roman shoes have just heels added in between the whole soles.

With the finds I am aquainted with nothing the like is reported, be it caligae or other kinds of shoes. Soles are generally flat with no trace of a raised heel. AFAIK raised heels are known from achaeological finds only from about the 15/16th century AD onwards.
