As a Podiatrist in Sports Medicine, this is a bit of a pet topic for me. Most comments above are correct...notice the common theme though...very individual. If you wear Beasts, then likely you overpronate at your REARFOOT (as soon as you make heel contact). The trick with going to a DS Trainer or Zoom Elite, is that they provide some pronation control at the MIDFOOT. The danger here is blistering through the arch, as your rearfoot pronates unsupported, with a midfoot support jamming up under the arch. A mid weighted shoe is smart however. I race in the DS trainer over ironman and marathon distances, and it is perfect for either heavier athletes/longer distances/or those who have never worn racing shoes. You should go to a specialty running store and run in them to assess fit and feel.
A lighter shoe with a bit of REARFOOT support is the Brooks ST Racer. If testing them at a store, put a ST Racer on 1 foot and a DS on the other. You will note the difference immediately.
If you have a history of injury to the lower limb, then you may in fact use a training shoe, but with less weight than the beast, again with REARFOOT control. I have a couple of patients who use the Brooks Trance as a 'race shoe' even though of course it is a training shoe. This way you get a much lighter shoe, but with a lot of cushioning and moderate rearfoot control.
Hope this helps!
