We present new spectroscopic observations of two high redshift radiogalaxies, TXS 0211-122 (z=2.34) and TXS 0828+193 (z=2.57), known to beassociated with large Ly$\alpha$ halos. The observations were taken with theslits placed perpendicularly to the radio axis. With access to pre-existingKeck II observations taken with the slit placed along the radio axis we areable to compare the properties of the gas in different regions of the galaxies.  In both objects we detect spatially extended Ly$\alpha$ emissionperpendicularly to the radio axis. In TXS 0211-122, the flux and velocityprofiles of Ly$\alpha$ are strongly affected by HI absorption/scattering. Inline with previous studies, we find evidence for outflowing gas along the radioaxis which may be the result of jet-gas interactions. In the slit orientedperpendicularly to the radio axis we find less perturbed gas kinematics,suggesting outflows of ionized gas in this object are focused along the radiojet axis. Additionally, we find evidence for a giant, UV-emitting arc orshell-like structure surrounding the radio galaxy Ly$\alpha$ halo, possiblyresulting from feedback activity.  In TXS 0828+193 a large Ly$\alpha$ halo ($\sim$56 kpc) is detectedperpendicularly to the radio axis. Along both slit position angles we findevidence for outflowing gas, which we argue is part of an approximatelyspherical, expanding shell or bubble of gas powered by feedback activity in thecentral regions of the galaxy. Our results suggest a diversity in the spatialdistribution of ionized outflows in powerful radio galaxies at z$\sim$2.5.
