I bought this as something of a last-ditch effort to stave off a visit to an orthopedic doctor. I've been having a lot of pain in my left foot and have self-diagnosed it as hallux limitus for now. After wearing them for a couple of weeks now, I do feel some improvement. I still have pain, but it's generally not keeping me awake at night. I placed them in my running shoes on my orthotics and I move those from shoe to shoe as possible (it does not fit in all shoes). I am probably still going to have to go to a doctor at some point, but this has helped enough that I think I can put it off for some time. These were well worth the money, in my opinion.
