Because I'm a huge fan of the Nike free running shoes, I figured these boots would be just as light and comfortable. I was not disappointed. I've been wearing these boots for 9 months and have had absolutely no issues. I've pulled numerous 12 hour standing shifts and these boots stay comfortable and my feet feel much less fatigued than in the Rocky's I used to wear. My one complaint is that they don't have the side zipper option, which would then make them perfect.
