Great Shoe !
The 880v10 is a more streamlined version of the 880V6 (which I also have and have run a approximately 600km's on) and less "clunky" than it's predecessor . It definitely has more stability with perhaps a bit less cushioning than the V6 , but is lighter. It's too soon to say how effective the Goretex is as we've had beautiful running weather as of late, but the V6's were amazing - through snow, rain, or slush my feet stayed dry. Am looking for the same performance from the V10's and is the main reason I bought them.
