Good running shoes for Haglund's Deformity?

I can't tell you exactly when it started appear, but i have developed the world famous bump near my heal/achilles. Trust me, i know it is Haglund's deformity. First off: I would like someone to clarify that this scenario makes sense: I believe that my Haglund's bump has caused my foot to land on the outside during runs, which therefore caused severe pain on the outside/bottom of my foot close to the heal. The pain is gone, however, my right foot (the effected foot) still tends to land on the outside. Of course i do not want to have to go through the pain again, so is there a running shoe that is good for haglund's bump, which would therefore cause my right foot to land normally again? Thanks
