Narrative:

PF was flying from the left seat of a king air C90; I was PIC and was sitting in the right seat. We were departing from ZZZ. It was the first takeoff of the day and the WX/runway conditions were not a factor. We had been cleared for takeoff and PF taxied onto runway 10. Once in position PF held the brakes and advanced the power levers allowing for both engines and propellers to spool up; released the brakes at about 600 pound torque. As PF continued to increase power she lowered her feet on the rudder pedals in order to remove her toes from the top of the pedals and re-position them to the bottom of the pedals. The airplane initially veered slightly left of the centerline which I called out. PF corrected by applying right rudder; however; in doing so the right heel of her shoe became jammed in the rudder pedal causing the airplane to swerve to the right. I immediately called 'abort; abort' and moved the power levers to idle. I notified the tower and PF taxied clear of the runway where we debriefed on what just occurred. The length of heels would not have been noticed due to the length of her slacks. In order to mitigate future occurrences of this type I will recommend that our flight program office put out a notice regarding shoe heel length. In addition; I will make it a part of my preflight routine to ask about it.

Title: BE-90 PLT MOMENTARILY LOST DIRECTIONAL CONTROL DURING TKOF. THE HEEL OF THE PLT'S SHOE INTERFERED WITH RUDDER PEDAL MOVEMENT.

Narrative: PF WAS FLYING FROM THE L SEAT OF A KING AIR C90; I WAS PIC AND WAS SITTING IN THE R SEAT. WE WERE DEPARTING FROM ZZZ. IT WAS THE FIRST TKOF OF THE DAY AND THE WX/RWY CONDITIONS WERE NOT A FACTOR. WE HAD BEEN CLRED FOR TKOF AND PF TAXIED ONTO RWY 10. ONCE IN POS PF HELD THE BRAKES AND ADVANCED THE PWR LEVERS ALLOWING FOR BOTH ENGS AND PROPS TO SPOOL UP; RELEASED THE BRAKES AT ABOUT 600 LB TORQUE. AS PF CONTINUED TO INCREASE PWR SHE LOWERED HER FEET ON THE RUDDER PEDALS IN ORDER TO REMOVE HER TOES FROM THE TOP OF THE PEDALS AND RE-POS THEM TO THE BOTTOM OF THE PEDALS. THE AIRPLANE INITIALLY VEERED SLIGHTLY L OF THE CTRLINE WHICH I CALLED OUT. PF CORRECTED BY APPLYING R RUDDER; HOWEVER; IN DOING SO THE R HEEL OF HER SHOE BECAME JAMMED IN THE RUDDER PEDAL CAUSING THE AIRPLANE TO SWERVE TO THE R. I IMMEDIATELY CALLED 'ABORT; ABORT' AND MOVED THE PWR LEVERS TO IDLE. I NOTIFIED THE TWR AND PF TAXIED CLR OF THE RWY WHERE WE DEBRIEFED ON WHAT JUST OCCURRED. THE LENGTH OF HEELS WOULD NOT HAVE BEEN NOTICED DUE TO THE LENGTH OF HER SLACKS. IN ORDER TO MITIGATE FUTURE OCCURRENCES OF THIS TYPE I WILL RECOMMEND THAT OUR FLT PROGRAM OFFICE PUT OUT A NOTICE REGARDING SHOE HEEL LENGTH. IN ADDITION; I WILL MAKE IT A PART OF MY PREFLT ROUTINE TO ASK ABOUT IT.
