i used to run in brooks beast and they were wonderful things and i really miss them....since i've gone on the scrawny side again from too many miles, i'm not pronating as much, and the beasts would be overkill.... i've gone for saucony grid hurricanes and these are nice too, but still have fond memories of my beasts (ahhh doesn't that sound sweet!!)
i didn't need to wear them in at all, never got a blister or an injury, and they were really comfy and lasted a fair bit...
