Valkenburg/Castleford style caliga step by step

[Neuraleanus]

As for convincing you, if you don't trust what c. van Driel-Murray said about leather thickness, hm, well, I guess I can only suggest to wait and see what Jutta Goepfrich will answer to my mail.

I also hope to get in a trip to the German Leather and Shoe Museum this year to see some of the finds first hand

I'm waiting anxiously to hear what you find out. The thickness of the leather is one of those important, yet rarely published details that we need to know. As I said, I've been guessing. I have friends who are also making their own caligae and they've been using leather thinner than mine. To go even thicker is going to be a shocking change.
