Yeah that's the exact boot I have. Rossi didn't make them regularly for a while, then when RB sellars bought out rossi they started regularly producing them again.

I bought them direct off rossi in one of this year's first production runs. Its unlined however there's a layer of felt in the footbed.

My question should have been, is this course felt layer present in your older mulga boots and do you have issues with stitched/cemented edge comming loose as a result of it?

Rossi was very interested in taking my boot back for inspection so I suspect they've altered the original design.
