Women's KACI II SLIP-ON

$125.00

  • Fit Tip: This style runs a 1/2 small and has a narrower fit than a traditional KEEN. We suggest ordering a 1/2 size larger than your usual size!
    Size Guide
Please choose a size! Please choose an inseam!

A go-to favorite for comfort and versatility with a cleaner, updated look. Well-crafted with full-grain, environmentally preferred leather and the all-day cushioning Kaci slip-on fans adore.

  • Leather-lined EVA foam footbed for rich comfort
  • Compression-molded EVA midsole
  • Non-Marking rubber outsole leaves no trace

We've carefully selected leather uppers designed to last. Then again, if you're wearing your KEENs daily, they won't always be scuff and dirt-free. To treat day to day wear and tear, especially on lighter color leathers, we recommend using a leather cleaner and conditioner, found at most footwear dealers and/or shoe repair shops.

    I was so excited for the Kaci II's to arrive. I've worn multiple pairs of the original Kacis for the last several years and loved the look of the re-design. Unfortunately, I couldn't even wedge my foot in. No matter how I tried, I could only fit my toes in, no use using a shoe-horn, the construction is incredibly rigid. Even my partner, with size 6.5 feet couldn't fit into these size 9 shoes! So sad to be returning these.

    Comfort straight out of the box

    5

    I wear Keen shoes almost exclusively, and have a variety of the footwear. I wear Keens to work every day. I'm on my feet quite a bit and wearing Keens keeps my feet comfortable to the point that sometimes you feel like you're not wearing any shoes. The Kaci slip-ons have quickly become a favorite! I have 2 pairs of the original Kaci slip-on, and recently bought this Kaci 2 slip-on. The Kaci 2 Is a little stiffer than its predecessor, but wears just as great as the original. Great room in the toebox, great traction and very comfortable.

    Did not allow for high instep; couldn't get foot in shoe!

    The shoe was exactly what I wanted - EXCEPT it didn't allow for a person with a high instep. Could not get shoe on foot. Made me very sad as this is the 3rd time I have returned Keen shoes because of instep issue.

    Way too small!!!!

    I own seven pairs of kaci's and have gifted a few more—absolutely love them but this pair doesn't seem to belong in same category. I thought I was safe buying the usual size but I when I received these I was sure they were mislabeled. Footbed matches my others but I cannot even get these one my feet. What a waste of money!!

    I wanted to love them but, no.

    I ordered these to replace my pair of original Kaci Full Grain Leather slip-ons. I read the reviews, I sized up half a size and I hoped for the best. As someone with a high-instep, slip on shoes are a gamble for me to begin with. But, the original Kaci's only took a day or two to loosen up for my feet. The Kaci II? Not a bit of give after wearing for two weeks. I would say that if your foot does NOT have a high instep, and perhaps your foot is slender, this shoe may work for you. The quality of the material etc. is still the same keen quality I've come to know and love. I hope keen brings back the original design of the shoe!

    Fit is not good

    1

    I loved the first version of the Kaci Slip-On, the look, the fit, the comfort! I had to return the Kaci II because it was impossible to put on. Super sad! It doesn't look as nice and I'm not sure why they had to change a good thing. I have so many Keen shoes that I love. I'm sad this shoe was such a disappointment. Maybe I'll try another pair and see if it s any better.

    Don't fit

    Kaci Slide and Presidio II fit beautifully so I was aghast when I couldn't even get my foot into this shoe.

    I would not buy these shoes again!

    These shoes are impossible to slip on because the elastic on the sides don't allow for any expansion. The best shoe ever is the original Kaci Full Grain Slip On shoe. It is fabulous. But Version II is not even on my radar, a real disappointment. My feet really hurt after just trying to put them on. Keen--are you listening? Please continue the original version! Thanks.

    Comfortable shoe after being broken in

    4

    This is a very comfortable shoe but only after a week or so. I almost could not fit my foot into the shoe the first couple of attempts and probably could have benefitted from a shoe horn. The shoe was soooo snug around the top of my foot but once it was "broken in" my foot slipped in with no problem. A few weeks into wearing the shoes they are extremely comfortable at my medical job!

    Not sure I would.

    I have bought this style shoe twice before so I was replacing the shoes. I read the reviews and they said that this style was now more narrow. It had only one slit ect. I looked at the pair I had currently and they had one slit so I thought I would be fine. It turns out they are more narrow instead of the perfect fit I am waiting to see if they "break in" so bummed. Love the style and the look the fit is off. I am hoping Keen will fix this splurge on the leather folks. I would only recommend if you have a narrow foot.
