Some time ago, I startet an attempt to reconstruct a pair of iron soles, protecting the feet of persons scanning and clearing a battlefield from hidden caltrops, as recommended by a
bellifortis after Conrad Kyeser of the Cologne Historical Archive of 1443, or as shown on the left image in post #14.
After a first one hour trial, they work really well.
