yea.
Definitely recommend. I bought some in black yesterday at my (somewhat) local running store when I picked up my New Balance 860's. Salesman recommended them for my plantar fasciitis and YES, they definitely help.
I was getting pretty down about my p.f. foot pain that, unfortunately, in past week had become nonstop. Was scared maybe I'd have to have a cortisone injection or worse...
In less than 24 hours I've noticed significant reduction in pain. Just ordered a second pair here in white (I live in warm climate) so that when I'm washing my black ones I'll have these ready to go!
You can get a much better price at OS1st site w/ promo code, but they don't offer expedited shipping.
OS1st seems like an awesome company that has shown me some light at end of tunnel.
