My podiatrist, (that made my orthotics) said there were good. She often used them for people who couldnt afford the custom orthotics. she also said that she was able to "adjust" them for people to customize them.<br><br>
I would guess if she would endorse them in that way, she felt they were good.<br><br>
I do have a pair that worked for me, but then I got orthotics and now use those instead.
