Why We Like The KEEN NXIS Evo Mid Waterproof Hiking Boot

The NXIS Evo Mid Waterproof Hiking Boot is the first fast-and-light hiker hybrid with KEEN's original comfort fit. It features a light and agile build for fast and easy hikes near home, plus KEEN's iconic toe boxes, which protect our toes while giving them some wiggle room. The NXIS also features a waterproof membrane for sloppy conditions and versatile traction with horseshoe-shaped lugs designed to grip muddy downhills, rocky uphills, and slippery sidewalks. With less weight than a true hiking boot and more protection than a trail running shoe, it's a lightweight solution for fast-packers, day hikers, and urban hikers alike.

Comfortable and waterproof

Returned another pair that were more industrial than I wanted. Got these - more my speed - lightweight, waterproof, hiker, that could be used for farm work. Really comfortable. Time will tell on durability, but so far so good, and I’m tough on my footwear.

Great boot for LEO

[This review was collected as part of a promotion.] I bought these after wearing Targhee EXPs. Wish I would have found them sooner. They have a lot of cushion and are VERY comfortable. Im about to order another pair just to keep in the closet. Highly recommend for any law enforcement officer.

Great Patrol Boots

I bought these after unsuccessfully trying two separate models of Hoka boots, both of which were too small. I typically wear Altra or Vivo Barefoot shoes, and I appreciate the wider toe box these have. They are very comfortable and I anticipate buying another pair when these wear out.

Not waterproof.

I wore my Keens NXIS EVO for the first light rain weather day. I was disappointed that both feet were wet in the heal after a 2 hour walk. I was walking on a paved road.

I don’t know

I purchased my first pair about a year ago and they are the most comfortable boot i have ever worn. They started to get pretty ragged so I bought another pair and the new ones killed my feet, so i had to go back wearing my older ones. I don’t understand it because my first pair was comfortable one day one.

Perfect patrol boot for police

This is my work boot and it is by far the most comfortable and durable boot I’ve owned! Light enough for foot chases and comfortable when standing for long periods.

Good looking. Feel ok on

Good looking. Feel ok on carpet, pavement and grass. For hiking on gravel, small stones and uneven surface, the footbed and cushioning are dismal. Hot spots from toe to heel and poor ankle support. Can you please suggest something more comfortable?

Super Comfy

[This review was collected as part of a promotion.] Have you ever tried on a pair of shoes and said, this is perfect. Well, this is the shoe/boot. They fit so good and require no break-in. I’m on my second pair. Do yourself a favor, get these boots.

Great hiking boot!

What a comfortable hiking boot. When it comes to footwear, I wear an 11.5 or 12 depending on the shoe. In Keens, 11.5 always fits me perfectly. So you may want to size down a half a size if you’re between sizes yourself. Can’t speak to the longevity of these boots yet, but for comfort and the sole these are a solid choice for your next adventure.

Greatest Keen I've known. . .

These have been the best Keen's I've ever owned. Size 13, straight outta the box, fit like a glove. Managed to get the rare Black/Evening primrose pair. To me, the perfect colors of black, navy and a lil that Keen neon green/yellow. If your a NFL fan, straight Seahawk colors. What was just to be my weekend off/day shoes turned into my everyday work shoe as well. Super light weight and durable plus waterproof. I've been wearing this same pair for close to over 2 years. Going on my 2nd pair now after wearing the sole's completely down to the point i can see numbers and letters on the bottom of the shoe it's so smooth but they've been so great i don't want to give them up. Only downside I've ever had with these boots is a small tendency for the top metal hooks getting hooked up when you cross your feet a bit.
