It depends on foot type as some have said above. I underpronate (feel roll out, higher arches, more wear on outside of foot and heel). I used to wear Asics or Mizunos all the time but I actually bought a pair of Nike BOWERMAN Air Pegasus 25's and with my superfeet Blue insole I have no issues. Nike shox aren't so great from what I hear. I stopped wearing them years ago. They are more fashion than function IMO.
