The Adidas Prime X and the Adidas Boston 10 were highly anticipated shoes, but the general consensus seems to be that neither of these shoes quite lived up to the hype. But I think there may be more to each of these shoes than was originally considered.

Boston 10 feels terrible to me. Gave it numerous chances but at over 340g for a more premium shoe it feels so over engineered. The plate in the heel only has the insole between it and your foot. Very underwhelming.

Great review!!! I totally agree with you in you impressions of the Boston!!. First of all I will say this Boston 10 runs a little bit small... I´ve used them yesterday for a 12K run after 113Kms on bike in the morning, having "heavy legs" and I felt that the shoe really helped me, I felt them as "energy saving shoe" so I enjoyed the run a lot thanks to this shoe. Also I felt also just a little bit of "discomfort" in the balls of the foot, not pain, but as if they were too rigid.. I want to test them in longer distances... probably not for a marathon but maybe well usable for a half-marathon... Also, I don´t think weigh should be so important, as long as there are no changes in velocity, stops and starts, turns, uphills etc... The problem with weight (you can see it pretty well in clycling) is just in the start, after that... if you maintain a constant speed, the more weight, the more momentum you have, so that´s not a problem

@andreasmaher8749 2 года назад

I have to hand it to Adidas, they were a bit late to the game with the "superfoams" etc....but they have since made up for it with a lot of innovation in their Adizero line.

@chada4701 2 года назад

Completely agree with your assessment of the Prime X - I took mine on a 14 mile run yesterday and my legs feel completely fresh today. I also can chime in that its important not to get sloppy with your form though, as I slightly rolled my ankle (on a straight section!) around mile 10.

@massi888 2 года назад

Nice review. i totally agree with you. i have both shoes and i love the prime x only the price i think is a bit too high. the boston 10 i really wanted to like it, i get that for a workout session it works well, but if you compare it to other shoes for workout for example the Fuelcell TC, i think it can not compare, i think even the adios 6 is better for workout sessions. Overall the new adizero franchise did great this iteration, the adios pro, the X and the 6 are excellent (the adios 6 a bit less :)), especially if you think how many great shoes are out there, we live in exciting times, expensive, but exciting :). thank you for your work, i really appreciate your reviews, the video footage today was amazing, love it.

My Boston 10s were fine till 90 miles when the lateral bias heel bevel combined with a compressed midsole caused shun splints, ankle issues. Me, back in the day: 3x1 mile repeats at 5 min/mile pace, 80% recovery, 4 minutes. Favorite workout.

@tfxcShoes 2 года назад

Greta comparison! I agree both are misunderstood. Some days I don’t mind the Boston 10, other days I can’t stand it. I think it’s about understanding what types of runs it works well for, and not comparing it previous Bostons.

@qpae8503 2 года назад

I think boston 10 is refreshingly different compared to any other shoe I've tried. It is very very cushioned but still quite responsive, and a nice racy type of fit and feel in the upper. It is heavy for sure (I'd really like it to be lighter) but anyway it feels quite pleasant and fluent to run at steady or somewhat fast paces. All in all deserves a spot in my rotation and look forward to the v11 in case they shave some weight off.. However if you're looking for a replacement for boston 9/8/7 you'll be disappointed. Better look at e.g. adizero adios 6 instead.

@m.r.6264 2 года назад

I love my Boston 10’s. Don’t have the Prime X, so not sure about that shoe. Edit: I’ve done ran a 15 mile course in the Boston 10 without issue. So I guess it depends on what you’re comfortable with. I’m going to run my marathon in a few weeks with the Boston

This is a firm shoe and somewhat heavy. Though there are some triathletes use this as racing shoe.. anyhow, would really wait in takumi sen 10 and adios pro 4. Instead of buying SL, Adios, & Boston series.

@GarethFreshwater 2 года назад

I have the Boston 10s and really like the lockdown, fit and ride. But as with everyone else, I don't like the weight! I can cruise along in them no problem, but I am training for Manchester Marathon and taking them out for 26 miles, when I'm no longer cruising and having to put in effort to keep my running form etc, the weight becomes noticeable. So I had to shelf them for race day and have gone with a pair of Saucony Endorphin Speed instead. Really like the trainers, but not for the marathon ironically.

@changliu9073 2 года назад

I tested the Boston 10 for like 3 weeks, before I quit it.... I did like the push-off sensation when you land on your mid/fore foot... but I just wish if the weight of this shoe can be closer to the Endorphin Speed 2 or at least the Velocity Nitro....

@MinhNguyen76 2 года назад

The push off sensation is suitable for certain running form. I am on 3rd run in the pair. Still hard as brick. :(

@Trailrunner1978 2 года назад

Great video about these polarizing shoes. I love the 6x6 min workout you do. 6x6min, 1 min rest is also a Jakob Ingebrigtsen, or Ingebrigtsen family favourite workout. And 10x1000 meter, 1 min pause. Both extremely good treshold workouts.

Seeing your stryd pod on mostly all videos I was wondering if you could use that data to deeper analyse shoes? Like objectifying energy return by being able to run a certain pace with less effort a.k.a. watts of power, seeing of asics magic speed etc. claims about improved cadence and length of steps match the data from stryd etc.

@jameswestmoreland9717 Месяц назад

I think Jack might have called these repeats "cruise intervals". A bit different from VO2 Max intervals involving more recovery but harder effort. Mine would be a mile at 5 min pace with 4 min recovery. The cruise intervals mught be 6 min - 6: 30 with a min recovery thrown in. Supposed to help people go longer on tempo/ LT runs. The Prime x probably would have worked out well back in the 70's and 80's.

Yes. He calls them cruise intervals. Supposed to be a 1min jog recovery but I find that way too hard

@zackbelcher3896 2 года назад

The thin strip of Light Strike Pro along the heel of the Boston is completely a lie. If you take out the insole you’ll see that light strike pro rises above the midsole that your foot sits on, it’s purely a cosmetic wrap. I tried on the Boston 10 side by side with Atreyu Artist yesterday as I’m finalizing my shoes for Chicago. I’m not sure what kind of cement they use for the Boston 10 but I hated it. I’d like to try the prime X but not sure I can get one in time before my last 18miler.

I discussed it at length in the original Boston 10. I think, at best, it may be there for either structural integrity of construction or perhaps to serve as a guide rail. but I think it's there in the rear more for show.

I like the Boston 10s however I have to admit though I find the Boston 10 seems a hair too tight than any other adidas or any other running shoe I got…..Nike….puma…Salomon…Hoka…..I wear a 10 1/2…..also the Boston 10s although to me it’s a high stacked or high cushioned shoe it’s also a bit firmer than most of my other shoes…..puma with their nitro foam got it spot on with their deviate nitro and puma magnify nitro. But the Boston is a firmer shoe until you “push” harder…….love going up hills with them though I can feel the spring action or the rods really working going up hill. Overall I think the Boston 10 will be in my rotation and will take over for my Nike zoom fly 3s…….retiring those shoes after 700 miles……😅
