I am 5'9 and 250 pounds.  I overpronate terrible when I run.  These shoes are not quite a cushy as my Glycerins or Transcends nor are they as flexible, but they are much more sturdy and take a lot more when I run.  I am a Brooks fan and absolutely love finding a shoe that will hold up to the punishment I give them.  I will buy more Brooks Beast shoes in the future!!
