Nike Free Run +3
Taken in the gym.
The purple ones belong to me :)
I own the Nike Free Run +3 Shield in Anthracite/Anthracite-Reflective Silver-Pure Platinum.
I also own the Nike Free Run +3 in Magenta/Sail/Reflect Silver
These are without a doubt the best running/exercise shoes I've ever bought. They're around $100 but long lasting and worth it.
Everyone who owns these says that they're true to size, but for me they were extremely small. I'm usually a size 7 in women shoes, but in the Nike Free Run 3+ I'm always a size 8, found this to be interesting. So ya, I suggest you actually try them on in store.
