The "comfort fiber" insoles are not substantial with no arch support. I have wore the shoes about 10 times over the past 10 months and my feet and ankles hurt the last two wears. So I removed the insoles  and they were almost flat. So I have replaced them with thick Reebok insoles and hope this makes them better. They get 3 stars because they still look decent even with color missing around toe area, and because I paid less than $50.  I don't think they are worth the high price they have jumped to.
