Thanks for your feedback.
We do use a thicker leather to a lot of shoe makers, our leather is 1.6mm - 1.8mm thick.
Our footwear is leather lined, which will take a bit of breaking in, however once broken in they will mould to your foot shape and allow for a very comfortable fit.
Once broken in, the thicker leather allows for more support than a thinner leather would.
Hopefully this helps, and thanks again for your feedback.
