Getting pre-IK pose in event graph?

I’m having some trouble with an IK setup. What I am doing is in the event graph I have nodes which are grabbing the position of the foot sockets. This position is used as a starting point to do a line trace that in turn provides effector locations for the IK nodes in the Anim Graph. The problem is that the event graph seems to be getting the location of the sockets from the previous frame which already had IK applied to it. This is causing some undesired behavior. What I need the position of the socket before the IK manipulation (the raw animation position). So is there a way to save the socket locations before the IK has been applied since the IK is moving the sockets and causing an unwanted feedback loop. How do I do this?
