Here is a pair of Lehigh Safety Shoes steel-toe leather ankle boots with a single monk strap. They are men's size 10.5 B. The Miragum soles are oil resistant and non-marking.
These don't appear to have been worn very much. They have some mild scuffs, and there is an area on the inside of the left shoe where something has taken the finish off (see photo). I have not polished them.
