My wife hated the color of the white/blue Nimbus 13s I had and they were the first in the series to hurt my heels since Nimbus 10s.  Finally found some in black and these 14s are awesome. Still a little flashy and bright for my tastes with the yellow, but they don't make a black and subtle.

I'm a neutral shoe guy and I have had multiple heel spur surgeries. These have been highly recommended by my podiatrist, and everything from Nimbus 10-12 and these 14s do the trick.  Happy feet again.

Now if they'd just make orthodics that fit into running shoes and don't squeek, that would be awesome....
