I usually don't drop so much money on shoes, but I felt like I read every review written and I was sick of my cheap Adidas. I'm flatfooted, run about 10-15 miles a week, and am considering a marathon so I figured it was worth the extra money. Took my first run in them yesterday and they felt great. The toe box is very roomy, which I'm not used to. I guess I was accustomed to having my toes jam to the front of the shoe! The heel is nice and snug, which balances the toe box well. Like every other review says, they are amazingly light-weight. Motion control and stability in running shoes usually translates to heavy, cinder-block trainers. Overall, a great purchase.
