When I bought these shoes I did not know my planter facitis would improve.  Within a few weeks of wearing these shoes it had almost disappeared.  When I try to wear other shoes the facitis starts coming back. I don't think you are permitted to make  medical claims for products in these reviews, I am just saying what happened in my particular case,  I am not recommending that people buy them for that reason but I had to remark on it because I was so plesantly suprised.
