^ ive seem that boot before and This is the first thing that came to mind:

I prefer the look of the Carmina jodhpur posted above over the AS alex. Jodhpurs look cool with a contrast of material and/or color. Some ideas:
Chocolate calf with dark brown suede leather strap
Calf with corresponding color croc strap
Navy calf with navy or gray suede strap.
The possibilities are endless
