Total Godsend
I've had PF in my right foot for a year+ at this point (I waited a looong time to do anything about it), and this has been a godsend.<br />They're basically arch supports that you don't even need shoes for. I'm a martial artist and train barefoot, which made finding supports tricky, to say the least. I wear birkenstocks most of the time, and started out wearing the Tandem Arch Pro Tech only when I was training, but pretty soon realized that it helped even when I had good support.<br /><br />I've worn it with all sorts of shoes (and none at all), and can comfortably wear it underneath my sock. Seriously - best thing ever. My PF is getting fairly close to being healed - I can go without supports now with much less pain, and I'm pretty good even when I first wake up (which is when PF is the worst). It didn't really start healing until I got these babies. Can't recommend them highly enough.  The only thing to be aware of is that I wore the wrong one for a while (I was wearing the left one on the right foot).  There's a label in them that says "right" and "left," so I just wasn't paying attention.  Even wearing the wrong one was helpful though (but it's much better to wear the correct one!)
