After having my second child, my feet unfortunately changed completely -- leaving me with a closet full of incredible shoes that no longer fit. I ended up ordering over 20 different pairs of running shoes, but nothing worked and I was almost done trying, when I stumbled across this shoe. Not only does it fit my new/slightly wider foot, but it's like running on a cloud! I'm so happy with this shoe, I bought it in a second color (the navy metallic and the charcoal)...and I'm now looking at a third option, too! While I know it's more for HIIT cardio type workouts, it's perfect for me to use on my treadmill (I run 3 miles x 5 days a week). Nike, please don't ever change this shoe -- unless you're going to add more colors!
