I have worn the shoes 3 times; twice for running (about 3.5 miles each) and once for a four mile speed walk. These are my usual distances, although I usually choose to run. After the second time I felt some pain in my feet and spent a lot of extra time stretching, etc. I have had plantar's fascaitis in the past, but have been in good shape the last 4 months or so. After the 3rd time I ran, I also had pain in my shins. Because of my issues in the past, I'm not sure if it's the shoes or me. I'm going to replace the Asics insoles with superfeet inserts which I used in the past and see how that might affect the issue.
