Since I have flat feet, I have to be very careful when choosing sports shoes. This one seemed like a good bet (given its significant midsole arch support), but I developed a huge blister on my left pinky toe after my first 5-mile run with it. I figured it needed to be taken apart and my legs to get used to it so I've been trying to incorporate it into my workouts for the past few months and it's still causing pain on the left side of my left leg. The pain also shows up when I wear them to buy groceries and other things. I'll go back to my tried and true toasted Asics.
