This is compelling. I am all but certain to pull the trigger on a non-GTX pair before March, so I have a Kool-Aid mustache as well as most of the posters in this thread. That being said I can't afford a pair of GS boots and a pair of Santiagos so I am hoping I can get the best protection possible AND have a pair of boots that I can walk around in. I'll swap the Sidis for more appropriate footwear where work or other indoor activities call. I hope this post is taken seriously and generates solid thoughtful discussion.
