Caligae Construction

[Matt Lukes]

Clearly, thanks to the scale that Paul put into the photos (good on you!), it's reasonably clear that the leather is between 4 and 5mm thick and that the widest section of strap is also 4-5mm. From that it can be seen that the narrower straps- the majority of them- are actually only about 3mm in width throughout virtually all of their lengths, save for the base where they're wider.
