These are the worst running shoes I've ever used and actually caused damage to my right leg... first, the ankle bones became bruised, then shin splints.  I went back to my old (completely worn-down) shoes and the pain went away.  Tried these Adidas shoes again and got terrible sciatica pain.  Stayed off the shoes for several days and the sciatica pain lessed a lot (still not gone, tho).  Tested the Adidas again with a brief walk and the sciatica was back in full force.  I've been running for decades and have worn many different kinds of shoes, and none of them caused injury besides these.  These are the structural problems with the shoe, I think:  The footbed is flat, vs. slightly elevated in the heel, as just about every other running shoe would be.  Therefore, every step forces ligaments, fascia, and muscles to overstretch.  And it causes great fatigue as well... every step feels like you're going uphill, even when on flat or downhill terrain.  There is also zero arch support, and the footbed can't be removed to insert your own.  Seems that the shoe causes the foot to roll outward in a dangerous way.
