Amazing fit - right out of the box
I was heading out to Zion for a week of backpacking, and needed a boot upgrade. I bought these after a thumbs up review in Backpacker magazine. The walk around the apartment was very comfortable. The sole is strong and durable, good fit, great ankle support, and lightweight for all of the included features. The fit runs slightly smaller - I usually wear a 10, but needed a 10.5 in the Stratos. My "break in" was a 2 mile walk on a city park trail. During the Zion trip, I never had a problem with these boots. Breatheability is great - I paired them with a lightweight wool sock; when temps were in the high 80s, sun out and dripping with sweat, my feet were staying dry. The only nitpick is that I've noticed the waterproofing fade with only a dozen or so trips in wet/damp conditions.
The Stratos is a great lightweight boot that truly has an "already broken-in" feel to it right out of the box.
