Left shoe = Left foot etc etc

Might Help
But seriously, there are some good replys here.
I used a flat, thin soled boot. Which was pretty flexible/supple. Helps to "feel" the pedals.
Like Tipweight, I also wear boots due to snow, mud. No !!!! though

And have no worry's about thickness of boots, just comes to time in the saddle.
I also remember being really heavy on the pedals. So try to relax a tad, and be nice and soft footed on it. Also try some hovering exercises with your instructor, like hover taxi along with differant power changes (not too high) and work on keeping nose in right direction. Hover Patterns and turns around a spot and keep nose pointing at the spot.
Like Whirls said, you only have 12 hrs. I bet there will be a huge differance by 20 hrs and so on if you keep practising hard.
It will happen man! Keep up the good work.
