Off-road boots with big calves

[Fudmucker]

I want to buy off-road boots for dirt riding.

I have BIG rugby forward type calves - 50cm circumference!
This seems to exclude me from the mainstream boots.
I've tried Alpine Stars, Thor, BMW, etc.
None will close at the upper edge - even on a size 12 1/2 !

Anyone with advice on a brand / style that may suit?

I'd like to go ATGATT, but nothing fits my feets -
or should I say covers my calves ?
