I've been wearing them for a week. My heels are hurting randomly now. I purchased for very early PlanTar Fasciitis on my left heel. I've given them more than enough of a chance. My feet/ankles don't feel supported and  "roll" out, not sure how to describe it. I decided to get a Vivonic insert for my old walking shoes and they are PERFECT now. My feet and heels are supported and both feet/ankles feel great! If you love your walking/running shoes get the inserts. The Vivonic shoe may be good for the heel but didn't support my whole foot adequately. Unfortunately I destroyed the shoe box but will try to return shoes anyway. I give inserts 5 stars!!
