I did not experience any pain from these shoes. I had to switch back to my Huawei Mate 20 Pro. Could you please specify in the product description that this is in fact the new formula to avoid deceptions like mine and keep the buyers correctly informed and not deceived. I did read feedback from otheBought this for my mom for Mother?s Day. so now I can?t give a better review. Looks awesome. I only had the shoe on for a couple of minutes, but did not feel comfortable. They appear to be durable but since they are new Im not positive. These are great though - they fit perfectly, are really comfortable and you can actually walk longer distances in them without your feet feeling strained and without them flip flopping. I had high hopes after owning a pair of Edipher audiophile bookshelf speakers, those blew me away.
