I spent some time researching shoes for overpronation before deciding to try these.  I know these aren't supposed to be the best of the best but I thought they'd be a nice compromise of price and function.  They were cheap but have almost zero stability for me.  I can't run in these without pain.  If you have neutral feet or only slight overpronation then they probably are great.  For serious over-pronators I guess you get what you pay for.
