I weigh about 200lbs. I am a moderate runner and does about 100 miles per month. I am running in this brand for about 10 years. I have an insert to give arch support. I will not even give second thought to another brand anymore. This Brooks Beast gives me 350 miles so I buy about 3-4 pairs per year. I have had no major injuries since using this shoe. I am sold on this shoe.  Over the years Brooks has improved the cushioning and heel so the heel last longer. So, if you are a sturdy runner and want to have no knee or joint issues run in the Beast.
