    Best sandals. Extremely comfortable and good fit. Jumped to the maximum rating with the solid black colors making them appear like work/dress shoes with black socks. :)

    Great Sandal, Perfect Fit, Zero Break-in

    Comments about Men's EVOFIT ONE:

    So happy Keen decided to add black (and grey) soles to these great sandals. I wanted to purchase a pair last year when they were released but the white sole was not for me!
    They sandals fit prefectly with not break-in required. I have been wearing them around since I received them. No regrets!

    Nice, soft and wrong

    By 

    from Mexico City

    Comments about KEEN Men's EVOFIT ONE:

    Because of its softness and fabric ,which is quite breathable, that is used in this amazing pair of sandals I will wear them for sightseeing in cities and in those places where the wildness is not presented. I can't see myself hiking through the Tepozteco mountain or walking the rough river where the rocks and branches can tear that knitted fabric.
    The reason I rank this product with four stars is not for quality of the materials is made, but for the information is provided to us.
    The size chart is wrong; according to it, size 13 is 29.4 cm long, but in the inside of the item it is written 31.
    I recommend the users to base their createria on the last chart in order to not have the same problem I've got now.
    I will wear them anyway because they are pretty nice and comfortable.

    EVOFIT- Best Keen Footwear Yet

    By 

    from Northwoods of WI

    Comments about KEEN Men's EVOFIT ONE:

    This Sandal is Great- true to size, very light weight, feels great on feet, not as sloppy feeling as other sandals, can wear barefoot or with light sock, sole offers great grip on the deck of our boats, sole is safe for cycling, good support for hiking the trails in the Northwoods, removeable insole is fantastic and this product is USA made. Price is reasonable for the quality of the product

    Comments about Men's EVOFIT ONE:

    These are my first pair of Keen sandals,my wife has the H2 that is what made me want a pair.I read reviews on all your products and people loved the H2 but said they were not super durable we are seeing that in her shoes.The evofit one on the other hand got great reviews and i really liked that they were made here in the states.As soon as they arrived at my door I opened the box,put them on and only take them off to sleep (just kidding).They are AWESOME,most comfortable pair of shoes I have ever owned.I work for Harley Davidson and traditionally wear Red Wing Steel toe boots,so these shoes are very different.I have not worn my booty since my evofit one's came home.
    Thank you for such a great shoe

    Very snug fit for high-volume feet, but nice

    By 

    from undisclosed

    Verified Buyer

    Comments about Men's EVOFIT ONE:

    This is an initial impression and early usage-based review. I have had these less than 2 weeks, so can't speak to the durability of the footwear or how the fit might change over time.

    With that said, here's what I think so far:
    - They fit very snug for the sizing. I wear either an 11.5US or 12US depending on brand, I got the 11.5US and they are the right length and width but the upper is very snug-fitting. I am hoping they stretch out a bit.
    - They seem well-made. There isn't much stitching to blow out, so hopefully the excessive stretch to get them onto my feet won't tear them apart like the previous Keens I had.
    - There is some Achilles rub, enough that I am still consistently wearing cloth band-aids with these. I am more susceptible to this than average, so if that's not an issue you often run in to you might not have any trouble at all with it. There's has been no noticeable "breaking in" so they continue to be a bit of a beast to get on and they fit tightly around my ankles.
    - They do look good. I really like the digital-camo-ness of the pattern. Not something I really expected from Keen, but happy to have it.
    - I appreciate that these are made in USA, if they actually are. The website says, "made in Portland, OR" but they shipped out of Ohio for delivery to New Mexico. Not sure why they would be shipped from the west coast to Ohio after production, just to be shipped again to the end user. Maybe warehouse space in Portland is just that expensive, IDK. I'm no logistics expert.
    - They feel secure on the ground, both on pavement and concrete as well as sand and grass.
    - The tighter fit and fewer and smaller openings mean they pick up far fewer pebbles and less sand than my last pair of Keens did, but what does get in is quite a bit harder to get out. They are hotter than my previous pair, though, for the same reason. Foam rubber footbeds don't breathe very well.
    - Haven't had them in the water yet, so can't talk about drying time or resistance to mildew
