Ghost 13 gtx meets ghost 13. Extra in the midsole is its own creation and does make the ride feel flat intially and the the extra tough heel did cause a cut on one of my heels. After a month all is very well though. Go buy it! As simple as it is.
It's the versatile Brooks Ghost you know and love, but in Gore-Tex! More breathable that other Gore-Tex shoes I've had. Add in waxed laces and pretty aggressive road tread, and you've got a great winter running option for short or long runs.
