I have not ordered it, as my insurance is covering the rental of a "DYNO" splint. This think is state of the art, and rents at $230/month. To buy it is $1,500.
I will tell you the splint has helped me. It's a temporary relief, but it's helped. The salesman told me to wear it through the night, but I have never made it through the night because my foot starts getting uncomfortable, or I feel my foot/leg falling asleep. I wear it long enough to give me relief. In the morning, before I get out of bed, I wear it for about 10 minutes, and I can walk. When I was having a bad day, I would put it on for about 10 minutes, and be painfree for a little bit.
Miracuously, I am painfree right now. I have not put the splint on for days. I don't know what happened. Since Physical Therepy I learned a lot of different exercises, mostly stretching, then with my splint, I was doing pretty good. I do not want to get over confident because I am afraid it will come back. I have suffered with PF for almost four years now, so it's hard for me to believe it is gone. By the way, it got to its' worst this year. Unbearable, can't stand it anymore kind of pain. SO, being painfree at this present day could be a trick. I'll keep you posted.
Best of LUCK!!!
