My friend has them and loves them but there so expensive you could get the spk pro for 100 dollars less
Ghost/Shogun=Falcon with 2 less buckles. the 2 heavy buckles weight more than the 4 light buckles do. 4>2 . Falcon lighter than Ghost. So get Falcons if Ghosts fit. I could move my heel around more in ghosts than Falcons(the buckle farther away from your toes on the lower part keeps your heel down well), and they just weren't as smooth somehow.. You can get a rubber bootboard for Falcons if you want to, something like $25. 09 Ghosts have the same flex as Falcon 10s did(not made anymore, but you can get them easily) and this years ghost is about the same flex as Falcon CS Pros(my boots, which I love).
Oh, but most importantly, if you are going to get a Salomon boot, you must get GOOD footbeds. I'll be using Sole footbeds, SuperFeet are more popular, and either will keep your foot in place, unlike Solly footbeds. Solly liners are crap too, so if you care a ton about that(I got footbeds, but not new liners for now) then get some good Intuitions(from the intuition site, I will if I win any comp money this year).
