I bought these shoes last week and walked around the house for a couple days, then took them to the gym and ran just over 3 miles. I found the shoe comfortable and cushiony with stability as expected. Today 3/8/14 I hiked 11.3 miles at Land Between the Lakes in Tennessee. The terrain was hilly, snowy, slushy, muddy (red clay mud that you sink into if you don't move quickly), rocky, full of puddles and even included a pasture :). Considering all the elements it was a challenging trail today. I am extremely impressed and proud to report that upon completion, my feet were dry, my shoes were CLEAN :), and I have NO hot spots. Though I am wiped out, my feet feel great. I am impressed with this shoe and amazed at the technology behind it. I definitely recommend! I plan on buying the mid-length boot in this same shoe as well. My picture below shows my shoes after the hike without being washed or wiped down.
