I am not cursed (or blessed) with sasquatch sized feet, but experience the same problem with winter boots. My solution last winter was to buy a pair of hiking boots that weren't as massive just for driving the xB, and trying to be very aware of "foot placement". Even so, with short term memory issues, the first time out this snow season I experienced some inadvertant braking while stepping on the clutch.
The pedal relationships are one of the few shortcomings of the xB that I would like to see refined.
