Although I have not had them very long, a few days, they feel better than any shoe I have ever owned. I have hiked many 14ers in Colorado and jogged on streets and trails for years, mostly in Nike. This is my first pair of Keen and I didn’t think I could ever find a shoe that was perfect for my idiosyncrasies. I believe I have found it. I weigh over 200 lbs and like a thick bottom and soft heel shoe. I am VERY, VERY impressed and will be buying another pair. I will also be exploring more Keen in the future.

I've tried various Keen shoes now. The H2O sandals are unbeatable, and I've tried a hiking pair of shoes that's okay. For working out, I've bought four Keen types, and this one is unquestionably the most comfortable, the Powerline.

My gosh, I wanted to like these shoes. They look great, fit really well, and felt awesome. I stand all day at work and they supported me just fine. But I returned two pairs because the tread was separating from the cushion after less than a week. That is simply unacceptable for any shoe, much less Keen. Kudos to Zappos though, for taking good care of me.

I've had these Powerlines for about a month, and have been appreciating everything about them. I have none of the complaints noted by other reviewers - no odor (after the first hour or so), no problems with tread separation, not too warm or sweaty (and I am prone to that!) They run about 1/2 size short, but width is excellent. Arch support is fine. The thinner blue or green ones maintain the same fit and comfort as the softer Keen insoles in these Powerlines. I also like the firmer midsole that Keen uses. They are distinctly less clunky/bottom heavy looking than many other Keens, and look fine with shorts, as well as jeans. They also are nicely light in actual weight.

I love my Powerlines. I had 8 pairs of the Keen Wasatch Crest and was nervous about trying a new model. They\'re great. Firm, stable, and comfortable. They were a bit stiff when I first put them on, but that went away within 2-3 hours. Keen fits my foot better than any other brand I\'ve tried. I highly recommend giving them a try.

My kids love them! These boots fit better (more like shoes) than any others we have ever purchased. My boys absolutely love the style...they wear them every day and winter hasn't even started. We are forever sold on Merrell.
