I've been running with the whole GTS series since 07, and have been pretty satisfied, but the GTS-11 is different in that it has a stiff heel "cradle" that caused me some issues on the outside of my foot. My old GTS-10's are pretty much shot, so I am trying out the Ravenna-2 as my next shoe. Ask me again in 30 days, after a hundred miles in them, and I'll give you an apples-to-apples comparison!
