      GREAT NEW KEEN DESIGN

      By 

      from LOS ANGELES, CA

      Comments about KEEN Men's EVOFIT ONE:

      Very impressed with these new Evofit Ones. I'm a size 9.5 or 10, narrower, lower volume foot, went with the 10 in the black colorway (the 9.5 was sold out, as are many of the sizes in all the mens colorways, so didn't get to closely compare the two sizes, which I generally bounce back and forth between). I'm coming to the Evofit from one of the non-Newport Keen models that I bought in 2013, but whose name I cannot recall and which has vanished from internet researchability. Have never liked the Newports. Too splayed in the toebox, clunky, geeky, warm-wearing. Tried the new Newport ATVs in the cool black/white colorway, regardless. They're less geeky, but I'm flatfooted and my foot was pressing too much up against the straps on the inside of the foot/show, and a built up welt on the edge of the insole. No such issues with the Evofits! The sock liner is dreamy. The last is narrower than the Newports by far and fits my foot way, way better. The insole is cloud-like on your feet. They're easily 35% lighter than the Newports, way more flexible sole, and way cooler-looking. Time will tell if all this luxe, supple comfort translates into durability. But basically, these are a running shoe with a ton more ventilation. Keen: you guys gotta get production on these things ramped up. You're gonna sell truckloads of them so let's get going on that, rather than having them on the site, but sold out. And let's see some other colorways eventually, like a blue of some kind, too Good job on this model -- winner!

      Another great sandal by Keen

      By 

      from NJ

      Pros

      • comfortable

      Cons

        Best Uses

        • light trail use
        • walking

        Comments about KEEN Men's EVOFIT ONE:

        I have been wearing my evofit for just over one month and they are extremely comfortable. They do have a snug fit but stretch to form to your foot. They fit true to size, my 11.5 are on par with other Keen's that i have owned.

        Best fit I have ever had

        By 

        from Boston, MA

        Pros

        • Fit like a glove

        Cons

        • Tight before worn in

        Best Uses

        • beach
        • camp shoes
        • Light hiking
        • Pool
        • walking the dog

        Comments about Men's EVOFIT ONE:

        I use these sandals for lite hiking, camp shoes the pool and walking the dog. Being a size 7 men's, I usually have a hard time finding shoes that fit. Last year I bought sandals at size 7 that were the right length but I couldn't fit my foot through the top opening. For the evo fits I decided to buy a 7.5 just to be safe. While the top is tight at first, the stretch material forms to the foot and gives without losing support. The 7.5 is still slightly roomy in the toe box but because of the material the shoe fits like a glove. The only con is I found that the material can be tight and cut off circulation the first few times wearing them but short of a custom fitting, the fact that these break in have made them the best fitting footwear I have owned.

        Best Uses

          Comments about Men's EVOFIT ONE:

          I've had these sites for about a week now and have been very happy with them. Super comfortable, and quite the eye catchers. Just know that they do hug for foot a bit if you have the wrong size. The only issue I've had so far is that just now taking off one of my shoes the glue that holds the foot sole to the shoe came loose. It's not a huge issue, I just have to be careful not to pull them off any further!
