After running about 40 miles in these shoes I twisted my ankle badly for no apparent reason while walking on flat pavement. I took a 3 week break from running and went out for another run and literally ran 30 feet and the same! It hurts so much Waited a few more weeks. went for a run. Drove 1.6 miles and BAM! Same ankle. Smooth asphalt. I had to call for a ride. I'm afraid of these shoes. I'm going back to New Balance which I've had for years. They appear to have a wider sole in the cure. I have crooked legs, but in all my years of running I've never had problems like this.
