MX boots for road use

Okay, this might be a dumb question but so far no one has been able to give me a satisfactory explanation.
Why cant I wear a pair of mx boots for road riding?
I ask because I am considering another pair of boots, and while 20 years of horseriding has done wonders for my calf muscles
it means that I have terrible trouble finding boots to fit foot AND leg. (Anyone who's seen me out riding will notice the electrical tape holding the boot closed).
