I just took a look at these pedals and I see that they incorporate a pedal platform/frame around them. I'm wondering if maybe the frame is catching the tread on the bottom of your shoes, preventing your foot from easily pivoting outward...
I'd rather be swimming...biking...running...and eating cheesecake...
