OK, I'll bet I'm the first person to do this boneheaded move: while waiting for a pedal wrench to remove old pedals and install new Shimano PD-A530, someone asked me to demonstrate how the shoe clips into the pedal. Making sure I grabbed a right foot shoe and the right side pedal, a proceeded to demonstrate -- without realizing I had the pedal 180 degrees in the wrong orientation. After pushing harder than usual, it clipped in -- but it absolutely won't clip out!
Not sure if it makes it worse that my cleats are SM-SH56 "multi-release" cleats. I really don't see how I can get them to release. Any expert insight?
