$140.00

  • Size Guide
Please choose a size! Please choose an inseam!

This casual, comfortable boot is ready for the weather, whatever it may be. Waterproof leather adds rainy-day protection, and a layer of light insulation keeps you cozy. A breathable lining keeps air flowing.

  • 100 grams KEEN.WARM insulation
  • Cleansport NXT™ for natural odor control

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.

    These boots are so comfortable! Wear them hiking and ATV mud riding!

    Cute and functional

    I love the way these boots look, they function like a normal hiking boots but feel very light and look less bulky than other hiking boots I have seen. The color is a bit darker than what was featured in the example photo but I like it more this way. I wore these while hiking for 2 hours in mildly hot weather, my feet didn't feel hot at all and when I got home my feet didn't hurt at all! My only complaint is the lack of arch support (which can be fixed with an insole) as well as the fact that the edge of the boot rubbed against my ankle and created a scab, I didn't feel it until I took the boots off though and this could also be remedied by wearing long socks.

    No arch support, runs wide and small

    I was encouraged by the other reviews, watched these go on sale, and ordered my regular size 7.5 figuring I might wear heavier socks in winter. These are plenty wide, but seem a size small even with thin socks. Most disappointing though is lack of contour footbed and arch support, which in my mind is a Keen standard. These are simply cute, light-weight, light-duty boots that you could probably get anywhere and confortabley wear Fall through Spring. Not the Keens I expected.

    I really like these. They're comfy & super cute. They do seem a little wide, but the size is a true fit.

    Bought my first pair as a gift for myself for Christmas. I wore several times a week. When I noticed these in sale, I bought some different colors. When I removed these from box, I knew they didn't need any breaking in. I just put on and wore all day with no problem.

    Typical well made Keen

    Even though these said they were for winter, I figured I'd try them since spring and fall and even summer can be cool in New England. I've worn them hiking twice. They fit well. They support the ankles which is what I was looking for. My feet stay dry in messy spring mud puddles on the trail and I'm looking forward to wearing them more.

    Love my boots!

    I have been looking at these boots for awhile now. I saw that they were on sale so decided this was the time to buy and so glad I did. Very comfortable right out of the box no break in time needed. I would definitely recommend.

    Very Comfortable

    My Plantar Fascitis has flared up again, and my Kaci slides were the most comfortable shoes I had. I like wearing a sturdier boot when I work, so the Kaci boot seemed like a logical choice. I added an orthotic insole to the new boots, and they feel great! I'm happy with my purchase and I expect to put many comfortable miles on these boots!

    Would buy these in every color

    I went down a half size—normally a 6.5 exactly, in these, like a lot of Keens of mine, size 6 is actually roomy. Extremely comfortable footbed; sure footing hiking and on slick pavement. I walk ten miles straight in these constantly and still find them comfy at the end of the day. Very lightweight too so no extra fatigue is created; remarkably waterproof and require only a minimal brush off of mud for clean up! (I use a dry rag and it works fine)These are the best hiking shoes I've ever worn ♥️Totally love them —plus they are cute to look at and work great with jeans or cargo shorts ♥️♥️♥️
