I’m 6’5 230lbs I ran a 3:45 with the Prime X3 We are heavy and we put a lot of force in the shoes The Prime X with the double plate will give you that extra bounce. Now they are a bit heavier but it’s a good trade off Prime X2 are more stable but I loved them both It depends of how much you want to spend NB sc elite v4 Brooks Hyperion Elite 5 Alphafly 3 Are really good options

Not sure if my experience of them is relevant as i'm a lot shorter than you, but i love the X3's. I love the bounce and the cushioning. My longest run in them has been 30k and i was surprised that how great my legs felt, and i could probably have ran a marathon distance in them easily. I can see why they would be great for a heavier runner actually - there's so much stack on them!

Prime X 3 because the energy return is so high that your legs dont feel tired in the slightest the next day

Prime X 3 for those long runs with fast segments

Did a 23km run with the PX3 and they are definitely an improvement over the PX2 The only thing would be that having 1 less pair of lace holes kinda gives the feeling of having heel slipage when going slow

getting some right ankle pain with the prime x3. sb2 is clunky at slower runs. mizuno feels the best for long runs. just got the cb max which is the heaviest but will need to try them in longer runs and see if it is good enough for a sub5 marathon. ap4 and zoomfly 6 are just too much for my ankle even at faster paces which are not shown in this video. and as you can see the cloudboom strike seems like the most stable for me but i probably need to replace the laces and improve the lockdown.

Hi. I mentioned the discrepancy because maybe it has something to do with the right foot rolling more than the left. Which supershoe im going with is not really the point of my post. i just wanted to illustrate from different shoes (that aren’t all mine btw) how they roll and why i was leaning towards the 2 shoes that i mentioned. I dont think those two are even that super. So i asked for advice aka fix, but not a specific shoe. From this thread i gather chance at orthotics and definitely strengthening exercises. Plus more mileage of course. Thanks! Video was fun.

on and off for almost 2 decades. yes a beginner in the marathon. thank you for this. i appreciate your advice and will keep them in mind. i do have stable daily trainers for easy and long runs. i think my intention really is to find a super trainer that could be a potential race day shoe that i can use during training. that why i did mention i was leaning towards the CB Max and the Vistas which are not really super super shoes. i was also asking for any fix, and i did get some good advice from this thread. thanks a lot.

i've been wanting to run a marathon since i was 25. i am 43 now. this is the first time i am able to fully commit to training and i am just being conservative. i hope my training does improve my form and fitness. i have 4 kids and a super demanding job. the only marathoner i know is my younger brother (hence the abundance of training/super shoes) who can probably do it without training, anytime. i just wanted to ask and hope for recommendations or advice. so far i got orthotics, lifting for strength, a few observations and recommendations, some ridicule, and your response which is the best by far.

thank you for this. i do have more stable daily trainers which are not in the video, puma foreverrun 2, structure, and an old kayano. its the weight and i just get so much fatigue even after easy runs. i acknowledge im still early in training and need to build strength. plus the excessive weight. really need to check other brands as you can see these are the more accesible brands from a nearby mall. im searching for a proper expert in inserts hope it works out well.

Yeah i agree. Need more training for sure. I think its normal to be impatient sometimes. Not really looking for a shortcut, there’s no way around miles set in a program. i think i want to make sure i get thru this training with less fatigue from the experience i have with my current daily trainers. I get carried away by the hype in all these new shoes while ignoring the fact that i dont have enough mileage and fitness yet. And yet, who wouldn’t want to make training easier right?

Oh it did seem like i own them all. But no. Me and my brother share the same size in everything. He knows almost every shoe and new tech in running. he is the runner, younger and fit. I only own 3 of those. Evo sl, vista, and cb max. Just like everyone here i agree i need to train and develop leg strength. I think its a combination of being anxious and ignorant that’s why im asking about this. But i am now doing runner specific exercises as a major part of my program. I am so glad to hear all these inputs.

yes i do have some right ankle pain in neutral shoes. but the fatigue in both legs i get out of stability shoes is worse although i ignore it and power thru in easy runs. i am considering more stable (neutral wide platform) max cushions from your nb and hoka recommendations. you give me hope. thanks.

What type of runs do you use it for? Technical drills? I really want to like them but I find the low stack hard on the legs, so maybe I'm missing something? I also run in the PX3S, AP4, TS11, B13 and Evo SL (+ATR), and all of these (except the B13) shine in their own area. Where I live (in Europe), the shoe is fairly cheap and easy to get, but even so, I've never seen another runner with them. Maybe because they are inaccessible in certain areas, they are more coveted?

Prime x shoes really love a high pace with strong push off. The carbon plates only work as springs if you compress them. So if you are able to put down some good amount of power in the shoes then go. Otherwise pick a different, non-plated shoe if you want speed and bounce.

Looks like you need to spend more time doing strength work. That will reduce your risk of injury and make you faster. As to running  I’d personally limit distance and focus on vo2 max exercises, that is my focus would be on muscle strength and cardio vascular capacity before adding the endurance element. Give it 4 months and do another run test (cool video by the way) and decide on shoes then. Edit: I noticed your marathon is this December so in just 3 months. Of those you showed in the video I’d pick the SB2. It would have been interesting to see you in AlphaFly 3, as they are super raceday shoes like ap4, but in my experience handle slower paces better than AP4. The carbon plate in AF3 just adds more stability than the energy rods in AP4 That is true for multiple of the shoes you ran in in the video: Prime x3 string really need a powerful kick to get bouncy, and is wobbly at slow paces. The evo SL and AP4 also require higher cadence and speed to get you up on the mid-fore foot to limit your inward sink. ON the same. So SB2 would be my pick.  Interesting alternative could be the new megablast or as mentioned the hall of fame AlphaFly 3
