The painted studs purportedly will flake over time which gives a beautiful aging effect (but I personally prefer the studs to be shiny and glisteningly new for ever). At ￡135 a pop you can get them via Oki-ni. Perhaps this can be the more affordable substitute (but not much more) of my escaped Prada studded brogues...
Anyways, these steel toe cap shoes, also from Dr Martens, are equally interesting:
