I wanted to like this shoe because I need replacements for the MBTs I have relied on for many years. These do not help. The shoe has less play than the MBT does, but the real drawback for me is the pain the Ryns cause in my left arch. My foot seemed to turn in at the arch. I tried three different shoes and had the very same problem, so I reluctantly had to return all. Thanks to Amazon and the company selling these shoes for allowing free returns...three times. I received the refund the very day I dropped the shoes off at UPS.
