This shoe is built after the 4th Century AD finds no. 1&2 from Deurne, Netherlands. The originals are single-piece design (upper pictures). I also built this model as multi-piece shoes with a separate outer sole (lower pcitures).
The find context was military and there is speculation that these may have been cavalry shoes. Whatever the actual use of these shoes was, they represent what seems to have been a shift in style which probably started in the late 3rd century.
