We propose a scenario to describe sunward generally dark plasma features originated above posteruption flare arcades. We show that, under certain circumstances, upward reconnection events can generate plasma voids sustained by the bouncing and interfering of shock waves. The voids, collimated in the magnetic field direction, are relatively stable structures that descelerates while approaching the arcade. The 3D simulations are compared with observations.
