    Hoka Challenger ATR2 – One shoe to rule them all

    More photos

    There is a lot of hype about Hoka shoes. Supposedly they are good for the feet and great for longer runs.

    With me not being featherweight, they seemed like the perfect solution for the longer runs. After spending a lot of time checking out the Hoka range I have decided to try the Challenger ATR 2 first because, in theory, they should be good for mixed surfaces.


    The Brand New ATR 2 Out of the Box


    When looking at the whole Hoka range, many of them look strange and clumsy.

    These are better looking than the majority of their models, although far from the "fast and furious" design like some other brands use. But most of the runners care more about their feet than shoe design, so it doesn't matter so much how they look, right?


    After reading online about Hokas, I was afraid that they could be too narrow for my wide feet, so I went a half size up. Still, they were a bit tight on my feet.

    But people also claimed that they adjust to feet somewhat and become more comfortable after 30-40km and that has proven to be true. After 30 plus km, they felt perfect on my feet.

    Shoes do have thick soles, but soles are not soft and squishy as could be expected. They are quite firm and responsive.

    Sole is noticeably firmer when compared with Adidas Boost or Altra Olympus for example. Maybe they don't feel like running on a cloud but they are really good for the feet.

    Note that I did have to use heel lock lashing system to avoid sliding of the heel because of going a half size up. So if you experience a similar issue, that could be a solution. Fortunately, laces are long enough for that (which cannot be said for all shoe models).

    Sole & Durability

    The grip does not look impressive and in practice, it is not really suited for wet and muddy trails, although it can hold adequately.

    Durability of the sole is excellent. After 200km of mixed terrain (probably close to 50% asphalt), the sole looks almost like new. Compared with some other trail shoes used on mixed surfaces, after 200km with my 90kg, this is impressive.


    ATR 2 Outsole after 200km 


    For comparison, below is Salomon Speedcross after less than 200km of trails, almost without asphalt.

    Lugs on front and heel were worn to less than 50%. So now you can see why I am impressed with these Hokas!

    Some people have complained to me regarding the upper and I have seen their shoes.

    The part where the shoe bends and little toe meets the shoe, it gets torn after 100-150km or so. Fortunately, mine don't have such issue and still look good, without any visible damages.

    If you are worried, the ATR 3 model has redesigned that part of the upper and that should not be a possible issue anymore. As you can see in the photo below, they still look almost like new, even after few washing.


    Challenger ATR 2 still looks brand new after a few washings


    Mainly I have used them for mixed surface workouts, with up to 50% asphalt surface. They have good grip for moderate trails, but even more importantly they are good on asphalt too.

    Few times I have used them on 100% asphalt workouts and they felt great on my feet. Comfort level on hard surfaces is not reduced and there is no loud noise when running on such surfaces like with some trail shoes.

    The drop is 4.5mm. It should be easy transition even if you are used to slightly bigger drop. I was used to running with a 6mm drop, so no adaptation was needed.

    The last workout was 36km of mountain trail with various terrain, a few kilometers of which was asphalt. My legs did hurt a bit after such workout but my feet were ok without any pains or blisters.

    In some other shoes, there would definitely be issues with my feet. I still remember the pains in my feet after 35-42km runs in few other shoes.

    Unlike some squishy Adidas shoes, due to the sole firmness and responsiveness, I think these shoes are quite good for racing too, not just for long workouts.

    You cannot expect racing performance on the asphalt like with real specialized road racing shoes, but they are noticeably better than your average trail shoe. If you want to see them in action, check out this great video of Hawks and Miller racing at 50 miles

    Stability on the trails is very good, even better than some other shoes which have thinner sole. They are not the most stable shoes ever, but considering the sole thickness, they are more than good.

    Perhaps that is due to the width of the sole and relatively firm compound used. Rocks and roots are definitely not an issue if you step on something and front toe protection is adequate for moderate trails.


    Hoka Challenger ATR 2 are designed to be versatile and I must say that this shoe is a 100% success in my eyes.

    They are so good that I got one pair extra for the future and I know few people who have 2-3 spare pairs of them. You can use them freely on asphalt and trails, without worrying about excessive wear or reduced performance.

    New Model ATR 3 has only small differences compared to ATR 2, for example, they have redesigned the upper on the spot where it tears for some people, so I will definitely get ATR 3 too as soon as I stumble upon a good deal. 

    As for now, I will enjoy this good pair of shoes!

    Hoka Challenger ATR2 VS. Altra Olympus 2.0

    More photos

    So right here, we have a face off  of two of some of the best maximalist trail shoes in the market.

    On one side Altra Olympus 2.0.


    Hoka is primarily famous due to the thick sole and is responsible for all the hype about maximalist shoes.



    Altra is more oriented towards natural foot shape shoes (involving wide toebox) with zero drop approach, most of their shoes do have thick sole but are not maximalistic to the Hoka degree.



    Both of these shoes are very versatile, usable on asphalt and not really suited for hardcore terrain, so I have decided to compare them as direct competitors in my eyes.

    I have used them during several consecutive weekends for long trail runs (30+ km  / 1000+ m elevation) on mixed terrain, changing the shoes every weekend.


    There are separate reviews written by me for both of those shoes if you want to read about them in more detail.

    Take in consideration that I have 90+ kg, so if you have 20-30kg less, then your experience with those shoes will probably be different.


    Hokas do look somewhat better and faster (especially in a variant with yellow-red gradient sole), while duckface design of Altras is probably not appealing for majority of the people. But we are not judging for Miss Universe, so looks are secondary in this battle.



    Hokas have 26-31mm stack height (front to back), while Altras have 32mm stack height.

    I got Hokas before Altras, expecting them to be like Adidas Glide Boost on steroids. Well, that did not happen. They do have quite firm (but elastic) sole. Comfort level was somewhat lacking at first, but they got better after 30km or so, they did stretch and mold to the feet to some degree. However for my 90+ kg soles are a bit too stiff for the really long runs.

    When I got Altras and put them on my feet, I was in heaven. They really are like walking on clouds. If they made identical shoe but with asphalt soles without trail grip, I would buy them ASAP for walking around.

    They are by far most comfortable shoes I have ever tried, Adidas Glide Boost (as a cushy example) are noticeably inferior to them. I do have Altra Paradigm, while they are very comfortable, they are not THAT comfortable as Olympus.


    Wide toe box is really good, your toes will be happy when not cramped in usual tight-front shoes, with which you must go 1 or even 2 sizes up to ensure they are not too tight.

    On long runs with 25+ km feet and legs feel better and less achy in Altras.

    So for the comfort level Altras win.

    Sole & Durability

    Both of those shoes have endured the first 200km without noticeable damages and with soles looking almost like new, so I would say that they are satisfactory in that aspect.

    Hokas did a lot more asphalt with lugs still practically as new so their performance is somewhat better. I did not experience tear of the material in Hokas near the pinky finger like some runners did. Perhaps Hoka did improve the construction without visible changes for the later batches of manufacturing.

    Anyway, both of them seem durable enough.



    Both of them have a similar approach with harder and softer components on the sole. Fortunately even softer part is good for now.

    For comparison, with approximately same mileage.



    While they are less comfortable, I think you can be faster in these Hokas.

    On few of my standard runs, I was somewhat slower in Altras. Probably due to the thick and soft sole in Altras which absorbs some energy, also there is zero drop which is (to me) slightly more difficult on climbs.

    With Hokas up to 20-25 km distance probably there is no contest. But with Altras causing fewer leg issues on long runs I am quite sure they would prove to be winners on 35-40+ km long runs, at least for me.

    Please note that your experience may vary, because of my weight which is over average for the runner. If you are lightweight then there is no such impact on legs while running and Hokas are probably a better choice, especially for racing.

    Both of these shoes work well on asphalt and concrete, so don't be afraid to use them on runs and races involving a mix of trails and hard surfaces.

    In my experience sole of Hokas is better for the hard surfaces. Lugs are almost not felt (and heard!) while running.

    Altras are louder on asphalt, but unlike most of trail shoes they are still comfortable and you can run without issues. Although I doubt that sole will be as durable as Hokas if used on a lot of hard surfaces.



    Both are best suited for mild trails, not involving a lot of mud and very rocky terrain. The grip on both is adequate, but for difficult terrain, there are much better shoes to be used (for Hokas that would definitely be Mafate Speed 2, for Altras maybe Lone Peaks, although I am unsure about how difficult terrain they could handle).

    Hokas have a big advantage because they are significantly more stable and because of that they can handle terrain with rocks and roots better, without worrying that you will sprain your ankle.

    Altras are very cushy and if you step wrongly then your ankle will turn to the side, possibly causing injury. They are very poor behaving on trails with side gradient, because they don't keep your feet stable enough.

    So Hokas can definitely handle more difficult terrain then Altras. But still grip is lacking for really difficult trails, also they are not perfectly stable due to the stack height even with such firmness of the sole.


    With Hokas I was never in a situation that my ankles were in danger, but with Altras there were few close calls. Fortunately, I tend to make smaller steps so there is time to react with other foot. If I was running with long hard steps like some people, I would be facing some problems. But still I must be more careful when going downhill, I cannot go  "all-out" like in some other shoes.

    In my opinion, it is better to not go off-trail, fell running or orienteering in Olympus.

    But even considering possible dangers to my ankles, running in Altras is so much more pleasurable. They are my current first choice when I go to a pure trail (a moderate one), but Hokas are chosen when there is bound to be some hard surfaces or when the terrain is more difficult.

    Toe protection

    Toe protection is slightly better in Hokas, but nothing extra. However sole is firm and fat, so that reduces the toe bumping issues. Altras are softer in the front so same care is needed.

    Beware that Altras have zero drop, so if you have achilles or calves issues, then be extra careful, start with very short distances and see how you feel in them.

    If looking for the multi purpose shoe for various surfaces, Hokas probably come as close to optimal as possible. Obviously, no shoe can be perfect for all surfaces, but Hokas have good performance on all except really hardcore trails with a lot of mud and such.

    Altras are somewhat less versatile, but also very usable on mixed surfaces. Maybe they are not so fast, but your legs will thank you after the race (if you don't sprain your ankle :D ).


    Both of these have some distinct advantages and disadvantages.

    Maybe it is best to compare them in a table:



    While Altras, especially for long distances.

    Unfortunately, lack of stability prevents me for taking them on more trails.

    P.S.  The new Hoka Challenger ATR3 are now out. As far as I managed to see and try in the shop, differences are mainly cosmetic, with revised upper design so that danger of tearing is now probably reduced.

    I don't think it's necessarily a different ride overall. There's just some issues I wish they would've improved upon, but didn't necessarily. It's still a solid shoe.

    It feels great, it runs great. This is now my favorite Hoka One One shoe to date.
