I do not run very much. Only 5K or Cyclocross. I have a very bad right knee. ACL is completely torn and some cartledge (sp) has been removed. I need a recommendation on running shoes. I think I will run in the woods for better cushioning; however I need your recommendations on a shoe. Are any brands or style better for my knee issue? 20 years ago I worked in a Reebok store and they explained the difference between a shoe with a board last and and slip last. The board lasted shoes just looked a great deal more beefy. Any help would be greatly apprecaited.
