I Think They are Great
I don't know why others don't like these.  You have to be able to feel the bumps for them to be working,  That being said, it took a day or so to get used to the feeling, but hasn't hurt since the first day.  And as to efficacy, again, didn't work the minute I put them in my shoes, but over a week or so, noticeable difference and after a few weeks, no longer need to take Tylenol before bed to keep from tossing and turning from the pain in my legs.  Simple solution without having to pay money to big pharma or doctors bribed by big pharma.  At the very least, worth a try.
