Aims. The co-evolution of galaxies and super massive black holes (SMBHs)requires that some sort of feedback mechanism is operating during the activegalactic nuclei (AGN) phases. AGN driven winds are the most likely candidatesfor such feedback mechanism, but direct observational evidence of theirexistence and of their effects on the host galaxies are still scarce and theirphysical origin is still hotly debated.  Methods. X-shooter observations of a sample of X-ray selected, obscuredquasars at z$\sim$1.5, selected on the basis of their observed red colors andX-ray-to-optical flux ratio, have shown the presence of outflowing ionized gasidentified by broad [OIII] emission lines in 6 out of 8 objects, confirming theefficiency of the selection criteria. Here we present slit-resolvedspectroscopy for the two brightest sources, XID2028 and XID5321, to study thecomplex emission and absorption line kinematics.  Results. We detect outflow extended out to $\sim$ 10 kpc from the centralblack hole (BH), both as blueshifted and redshifted emission. Interestingly, wealso detect kpc scale outflows in the [OII] emission lines and in the neutralgas component, traced by the sodium D and magnesium absorption lines,confirming that a substantial amount of the outflowing mass is in the form ofneutral gas.  Conclusions. The measured gas velocities and the outflow kinetic powers,inferred under reasonable assumptions on the geometry and physical propertiesof these two systems, favor an AGN origin for the observed winds.
