The pilot stated that during landing the airplane drifted to the left side of the runway prior to touchdown. He attempted to correct with right rudder application but was unable because his shoe was lodged between an object and the rudder pedal. Slight aileron input was ineffective and additional aileron correction was not applied in order to prevent the right wing from contacting the runway. As the pilot applied full power for a go-around, the left flap contacted a runway edge light. The go-around was routine and the pilot returned and executed a normal landing. The left flap and left portion of the stabilator incurred damage. The pilot stated that there were no mechanical abnormalities present with the airplane prior to the flight.
