Wow, GW, perfekts are the least comfortable pair? Yikes. I'd say for most people the opposite is true. For me, they are almost too comfortable. They are too much like a pair of running shoes and too soft and comfy. I've never heard anyone complain that they're uncomfortable.
Here's a review that I did on these boots and others a while back.
http://www.youtube.com/watch?v=VfApS_NRQjgMy favorite lately have been zamberlans - specifically the Zamberlan Vioz Plus GT RR. I also really like the Lowa Tibet. Of the ten or so boots I've tested in this category, my least favorite has been the kenetreks for several reasons, primarily being it just didn't fit my foot well (we're all different there). Others put the Kenetreks as their favorite, so it's pretty subjective.
Hope the video helps.
