I am only writing this review for those who suffer from SERIOUS flat feet like me. I have a 2 degree arch (measured 2.5 years ago) that causes severe knee pain and tendon pain on the inside of my legs. I need full motion control that the Brooks beast and the original Redeemer ISO provide. I know some people will reject that because they think the support is fantastic. And this is for her. But if you're like me, then these shoes don't fit you anymore. I took 3 steps and immediately noticed my bow collapse. It will cause me severe pain after a few minutes even when walking. With that in mind I gave the shoes 3 stars because they have lost a lot of weight and are much more comfortable than previous editions. But they are unsuitable for me because they are advertised as tight controls overpronation when in reality they are not. The original Redeemer ISO and Brooks Beast are the only ones who can tell now. Now they are designed for moderate control rather than serious ones.
