Loved the 10, hate the 11. Hard to describe why -- it just feels stiffer and clunkier, and (visually) they stripped off the silver flashing and off-center lacing, which I actually liked. The 11 looks more dated. It comes in a variety of colors, but my running store only carried the boring blue and gray. Bleh.

I haven't noticed any real difference in my runs, but I wear my 10s for everything but running, and I always feel happy when I put them on.

Hoping we'll soon be at the Nimbus 12... and that it will be more like the 10!
