Feels really similar to the 14, but the battle Knit is more clingy to your foot. The heel area has the most room. I wouldn't say it is narrow at all.
I am going true to size for ball or casual. I usually wear Nike elite or stance performance socks to ball and it would snug it up just right so there is no movement.
I can't say enough how much better the Ashes look in person. There is almost a shine to the material. Best looking (at least the Ashes and model to me) since the 10 and 7, which are some of my favorites.
