    Holy Hoka Kaha

    More photos

    Man, the colors are retro and loud! However, my 10-year-old really liked the colors. If you don’t like the colors, there are other options available.



    I didn’t get to pick the color, these shoes were provided as test mules, and now I have grown to like them. Prepare yourself for answering questions when you go out with your friends to hike, though.

    After admiring the colors, I put the shoes on to see how they felt and fit. I usually wear a size 10, and once I had these on, I felt like they ran about a half size larger than I’m used to.

    This was not a big deal as I wear a pair of sock liners and then my wool socks and once, I had both of them on, the boots fit well.

    I have run in Hoka One One shoes in the past and loved the cushioning but had some issues with stability. So, I had reservations about their boots.

    The cushioning was what I expected from Hoka very soft and comfortable, thanks to their “Rangi™ bottom foam and patented geometries”.

    Regarding their adjustable lacing system that provides lockdown fit regardless of your foot type, I can only speak to my foot type, and the boots did fit well and felt supportive once laced up.



    I did have some questions to what the yellow ribbon piece that the shoelaces run under was for. I assumed that it was to keep the boot’s tongue in place.

    However, its function appears to keep the laces from sliding over the top of the shoe. The lockdowns, last two eyelets did pop into place and held the laces securely.

    Time to make like a horse turd and hit the trail

    My family loves to go hiking, and we go out every chance that we get taking advantage of living in the rocky mountains.

    We live right at 5000’ above sea level. Thus, we can be on a trail in less than 30 mins and can be well into the high country in no time.

    I often train in the mountains for ultra-marathons and know where to take the family to see the best of the best depending on time.

    I have many pairs of hiking boots ranging from custom made to cheaper off the shelf models. The Hoka One One Kaha doesn’t look like a traditional hiking boot and doesn’t feel like one, but how does it perform.

    It was an absolutely miserable day out with temperatures in the mid 30’s F and non-stop rain. Rain in our area is rare and provided the opportunity to test the boot in wet conditions to see how well the Vibram® Megagrip traction would perform and how waterproof the boots really are.

    The first step out on the trail I immediately felt the plush cushioning that the Kaha offers, not only this but the shoe is super light. My kids and I had set out on an easy 5-mile hike with a rather modest 1200’ of total elevation gain and loss.


    An obviously posed shot to show off the meaty lugs on the Kaha as well as their grip on a wet rock.


    I purposefully tried to get the boot to slide on slick rock and could get them to slip on ridiculously steep wet granite boulders. To my amazement, the boots held on anything that anyone would common sense would attempt to walk on.

    Would they ever slip? Yes, but only in the worse of conditions and not ones you would ever truly expect them to hold traction on.

    In the mud, the lugs provided good grip but would get lose traction when the mud was really slick, or the lugs would fill with really sticky mud. I never felt like I was going to fall due to lack of traction. However, I could feel slipping when walking across mud.

    Watching my kids walk across large areas of mud, the Kaha was performing much better than their boots were.


    This picture was from a different hike that involved very sticky mud you can see how the mud clings to the boot:


    During our first hike, I was able to test the boots for waterproof through multiple creek crossings. Trying to get decent photographs to share with readers, I would often pause to get the right picture and to have one of my kids shoot video.

    I was amazed that I never once had water leak into the boot, my feet stayed dry, as long as I kept the water below the top of the boot.



    At the end of my first hike in the boots, I was pleasantly surprised by the lack of impact that I felt my legs had taken and how fresh I felt. The boot's lightweight built allowed me to climb small hills without feeling like I had to pick up heavy legs.

    My feet weren’t sweaty hot like they normally get during hiking, and they weren’t wet from the rain. I felt like this was a huge success for the Kaha on their first hike.

    Over the long haul



    I managed to log nearly 500 miles throughout a couple of months. Most of which were with a heavy pack in the high country with winter conditions.

    I tried my best to beat these boots into submission, even kicking stones to test the toe guard. I wanted to find a weakness and thought that stability of the boot would surely fail when scrambling across loose rock while side-hilling.

    I threw the best and toughest conditions that I could find at these boots, trying to find a flaw. I thought for sure during my last adventure, I would find the pea under the mattress.

    I was going on a 10-day camping trip where I ended up covering over 150 miles all between 5000’ and 12,000’ in temperatures that would range from -4F-50F.

    I brought along a pair of winter hiking boots since the temperatures were going to be so cold. What I found was that the Kaha never got too cold even in the deep snow.



    I had tried to wear my winter hiking boots but just found them too heavy and not comfortable to hike above 8000’. The Kaha was light waterproof and stayed warm enough to be my preferred boot over the ten days in the mountains.

    I tried to take more photos, but the freezing temperatures kept killing my camera, so I snapped as many as I could until the camera would shut off.

    High in the mountains walking snowy ridges with a heavy pack, I was sure that I was going to lose stability. The high sole with the cloud-soft cushioning screamed to give way under my loaded down weight.

    But it was not to be—the boots held up through every turn over every ridge. While there is some give my feet and ankles always felt well-supported and comfortable.

    Over long hard miles a day in and day out, I was happy to grab my Kaha’s every morning.


    Wrap up


    • The full-grain waterproof leather has stayed soft and was shows no signs of being damaged. I punished the boot going through briars, water, and rocks and they took no damage just got dirty.
    • eVent waterproof booties kept the water out and my feet cool and comfortable throughout all of my testing.
    • Rangi™ bottom foam has held up and shows no deformation over the 500 miles that I have put on the boots. The boot is still as plush and soft as the first day that I got them.
    • Vibram® Megagrip hi-traction outsole never let go of their grip in the snow or rain on rocks or dirt.

    Aside from getting dirty, the boots held up amazingly well, there isn’t any glue coming loose no pulled stitches, and they are as comfortable as the day that I got them.



    • Toe guard was enough to protect my toes when I kicked rocks and smashed into tree branches.
    • The heal guard kept my heal and safe when bouldering and hiking through rocks
    • The laces are robust and show no signs of fraying
    • The lace locks hold tightly in place even if they come untied (I never experienced them coming untied while hiking but did untie them and walked around to see if they would loosen)


    • Cushion
    • Stable
    • Well-built


    • Run a half size to full size larger than standard


    I have section hiked more than half of the Appalachian Trail (AT) as well as a large portion of the Continental Divide Trail (CDT) and many many miles on some of the hardest and most beautiful hikes.

    During this time, I have gone through many boots and never thought that the Hoka One One Kaha would be one of my favorite boots if not my favorite.

    If I’m going long miles, high country, or through water the Kaha is my boot. I would love to hike the whole AT from beginning to end, and if I ever get the opportunity to do so, you will see me in a pair of Kaha’s.

    If Hoka ever wants to sponsor a through-hike of the AT, I will be in line, raising my hand and begging to be the one who gets to go.

    This boot is truly holy.

    Hoka One One Sky Kaha - One small step for man, one giant midsole for hiking

    More photos

    "That's one small step for man." I jokingly said when first seeing these moon boots in comparison to trail running shoes; I normally use for hiking.

    Despite these fitting in with the Hoka brand with their large and "clown shoe" size, I actually love the look of them! The black/grey colorway, as Hoka calls it, is vibrant and eye-catching with its bright red bottoms and orange accents. Well done, design team! 


    Tech specs

    The Sky Kaha is a very lightweight backpacking/hiking boot. Sizing is fairly standard and fits the same size as a running shoe.

    It weighs in at 17.9 oz (508 g) in a Men’s US 9, making it nearly half the weight of most comparable boots. With a heel-toe offset of 6 mm (33/27), the Kaha has a very smooth and effortless heel-toe transition, while offering the maximal protection one expects from a Hoka product.



    Thus far, I have put about 200 miles on this pair of shoes and have had no issues with premature wear. The only place where there is evidence of wear is in the Rangi bottom foam, which is what Hoka is calling the soft midsole foam between the top EVA layer and Vibram outsole.

    I have used these shoes for hiking all across California in Yosemite, the Sierras, the San Gabriels, and Zion on very rugged and rocky terrain, and they have held up amazingly well considering what they have been put through.

    As for the upper, there is no sign of wear, and I anticipate these shoes to last for hundreds of more miles with the limiting factor seeming to be the soft midsole.



    One of the great feats of design with the Kaha is the eVent upper, which is comprised of full-grain waterproof leather.

    Hiking mostly in California, I had a concern that the leather upper would pose an issue with heat and hot spots, but I have yet to experience either even when hiking Half Dome in them straight out of the box!

    As a trail runner and hiker who usually just repurposes trail running shoes for hiking, I was pleasantly surprised with how supple the upper feels on foot. I have not needed to wear liners or double up on socks or alter anything as the upper just works seamlessly with no hiccups.



    Also, the waterproof aspect of the upper is a huge plus and feels better. It is more breathable than a Goretex upper on a trail running shoe.

    Being a mid-cut made this an even easier transition from trail running shoes with no risk of Achilles hot spots.

    Lastly, I really love the adjustable lacing system! The paracord style laces are great for providing a solid lockdown while staying out of the way. This is aided by the length being very good and being spots in the orange loops to tuck the ends in.

    Midsole & ride

    The midsole of the Kaha is made up of two layers: EVA top layer & Rangi bottom foam layer.

    This combination makes for a supremely plush ride. For long day hikes, these have to be some of the most comfortable and resilient shoes I have ever worn.

    Keep in mind these are neutral shoes and, therefore, might not be supportive enough for some people. For those with a neutral gait, these are very well cushioned and feel like walking on a cloud even when covering nothing but rocky terrain.

    Two primary concerns with highly cushioned shoes are protection on sharp objects and maintain proprioception on slick terrain. The Kaha passed both of these tests with flying colors as they have kept my feet feeling like brand new even on rocky 20 plus mile hikes and felt very agile even when summited the slick slopes at Half Dome.


    It has 5 mm lugs that provide excellent grip in the sand, soft mud, scree, and slick granite.

    The grip on the Kaha is top-notch due to the utilization of it’s Vibram Megagrip hi-traction outsole. This allowed Hoka to strategically minimize weight while having a very durable and sticky rubber outsole.

    From past experience with similar outsoles and looking at the status, it appears this outsole will allow for many hundreds of more miles to be put on this pair of shoes. There is no sign of accelerated wear, just a little bit on the soft outer midsole.



    The Hoka One One Sky Kaha is an amazing all-around hiking boot and easily the best all-around shoe I have used for hiking and backpacking.

    It is supremely lightweight and feels like a running shoe both in weight and the midsole ride that I thoroughly enjoyed coming from a trail running perspective. The stack-height and drop are also great for promoting a smooth and protective ride.

    If there is one concern I have with the Kaha, it’s that the price tag of $220. It is definitely on the higher end, but then again, it is an amazing shoe and worth every penny for a very serious and active hiker.

    Those looking for a do it all shoe with a breathable yet waterproof upper, lightweight construction, plush cushioning, and aggressive traction will fall in love with this Mercedes of a hiking boot.

    Once I got my foot in, I was extremely impressed with the lightweight feel and also the responsiveness of the Kaha.
