A host reviews and ranks his running-shoe rotation for daily training, recovery, racing, and trail use, arguing shoe choice depends heavily on runner weight and stability needs.
No guests appear in this episode; it’s a solo “bonus” review. The host mentions prior shoe episodes with Alistair Brownlee, Stephen Scullion, Hugo Fry, and Alfie Manthorpe.
Vamiro Plus is safe for most miles but not for hard Zone 3+ efforts; Nike Vapormiro Premium is comfortable but too soft/floaty for faster running; Alpha Fly 3 vs Adidas Pro 4 is a close race, with Alpha Fly preferred for responsiveness; Adidas Prime X3 is his top pick for heavier runners due to stability and power despite being heavy; Sockany Endorphin Elite Pro 2/3 are very soft/springy and less stable for him; Adidas Agravic Terrex is ideal for grippy off-road ultra training.
Prime X3 described as “Formula One” tech with Continental sole, Lightstrike Pro section, plate and rods; Terrex used for Project 7 marathons, Desert 30 in 30 days, and Snowden six sides in 24 hours.

Hope you're all well. These are all of the different running shoes that I've used over the last few years. I'm gonna be giving you my opinion on all of them.
2:31So, the Vamiro Plus from Nike. Super safe shoe. I use it for the majority of my sessions every week currently at the moment. I'm relatively new to the shoe. It's got pretty good support. It's nice. It's soft. You're not going to hurt yourself or injure yourself covering lots of miles in this shoe. They are not plated and they're a fantastic option for just kind of everyday running. For me personally, when I start pushing kind of, you know, into the depths of zone three, so call it kind of 155, 160 heart rate, these are no longer of use. Past that stage, I want something a bit more racy, a bit more supple, great bounce, good responsiveness for a recovery shoe.
3:17This, in my opinion, is top dog, the Nike Vemiro Plus. The Nike Vemiro Premium. This is basically an enhanced version of the Plus. As you can see, it's got quite the stack. It's beyond 50 mil and it comes with a not approved by World Athletics logo on the back, which is interesting because some shoes are banned for the reason that they would help you in a marathon. So say the Adidas Prime X3, which we're going to come onto in a bit for having a large stack. This has a large stack, but it would be incredibly slow for a marathon. So interesting to see that, you know, the stack doesn't necessarily benefit your pace.
4:05This is even slower than this, as far as I'm concerned. This is like an amazing shoe to walk around in. If you're on the shorter side, it gives you about three inches, which is pretty lovely. When I wear this, I am six foot two. So, you know, this for me is a monster winner. I personally find from my experience that running hard in this shoe is a little bit too bouncy for me. I think it's a tremendous shoe, but basically if I'm going anything over, call it 4.45s, I feel a bit out of my depth in this shoe. It's a little bit soft, it's a bit floaty, it's quite wide. I don't get the kind of responsiveness I would want.
4:51The extra squishiness, the extra height can kind of create problems for me because I put probably more weight through my stride than say some of my friends who weigh 70 kilos who are you know elite runners so so for me this really has become more of a casual shoe um you know the plus is used for maybe 60 to 70 percent of of my of my runs moving into the adidas versus nike battle let's compare the alpha fly with the pro 4 this is typically what you would see as the lead dog from adidas this is without looking at the new sebastian saway 450 pound super shoe that everyone's raving about you know this is that but not quite as advanced a slightly heavier version with a larger stack but very similar tech uh to the now very famous sebastian saway uh and kajelcha shoe from adidas this is the nike equivalent the alpha fly three.
5:54Both super famous, excellent shoes. You know, were you to appear at any marathon, you will see literally thousands of people wearing these. This is kind of number one from Adidas, really, in terms of, you know, commercial availability and number one from Nike. I've raced marathons in both of these shoes. There's not too much in it as far as I'm concerned. For me, I love the feel of the Alpha Fly on my foot. I find the Pro 4 is pretty responsive. Although for me, I have a slightly wider foot and my foot does kind of tend to hug the side of the Pro 4. So I feel like I'm kind of like diving over the top a little bit of the Pro 4.
6:38Having said that, I've not lost any toenails racing a marathon with the Pro 4 and they're a super responsive shoe. These feel like a little bit squidgier. I personally think that for the slightly heavier runner, the kind of 80 kilo plus, you might feel more responsiveness from the Alpha Fly. You might get a little bit more snap from the plate. If I had to pick one of the two, I would probably go for the Alpha Fly. But please don't hate me, Adidas, when I lose weight, which I'm sure I will on my road to 245. This could all change. Coming back to Adidas and probably my favorite shoe of all time, we have here the somewhat controversial Prime X3.
7:20This, to me, is kind of, you know, Formula One, top of the range material. This is the kind of shoe that just has a lot going for it. Like it has a bunch of tech in it. You can visibly see that this shoe has an awful lot of tech. It has a really firm sole made by Continental. A lot of people, a lot of Adidas shoes also have a similar sole to this. It then has a light strike kind of pro softer section that gives it this large kind of front stack height followed by a plate. And it also has rods going through it. So this has rods. This has a plate. This has both. And it also has kind of tremendous stack height.
8:06It has this stack height combined with this plate and these rods. So this really is kind of like a big hybrid super shoe monster. But with it, it's incredibly stable. I feel for the slightly heavier runner that I get so much out of this shoe. A lot of elite athletes won't wear this shoe because it's very heavy. It's a lot heavier than anything else on this table. Certainly these racing super shoes over here. and you can really feel that in the shoe like you feel that you're wearing something of weight but I don't so much mind that you know somebody heading for the podium in a marathon would never wear something like this it's far too heavy but for me I get an awful lot of responsiveness out of it I feel that my toe strike is pretty much perfect in it I tend to I tend to roll my foot in some of these lighter models my perineal is quite tight from all the mileage that I'm covering and so my foot naturally wants to drift off to the right.
9:06And so I end up striking with the outside of my foot in the lighter shoes. Not so much with this. It feels really balanced. It delivers an awful lot of power to me as well, this shoe. And at the end of the day, I just feel really comfortable in it. If you're an athlete that hasn't tried this shoe, and perhaps you don't weigh kind of 70, 75 kilos, you're slightly on the heavier side, my recommendation would be wholeheartedly to spend the money on this shoe. This is my favorite shoe by miles. And by the way, good news is if you are not a professional athlete, this is absolutely fine to wear in an official race.
9:39A World Athletics sanctioned official marathon, not a problem. It would only come into question if you were an elite professional athlete, which is not us. So off we go. So that takes my top spot. You can train hard, eat well, feel fit and still miss what's going on inside your body. Dr. Rangan Chatterjee, founder of Do Health, told me that 46 % of members had hidden cardiovascular risk that they had absolutely no idea about. You know that I track everything, sleep, recovery, training, and performance. But there's a difference between feeling healthy and knowing that you're healthy. I took my blood test last week and the results are in.
10:15I've also asked the AI to give me a breakdown of these results. And here they are. It says that they paint a really clear picture of someone who trains hard and eats plenty of protein, tick, and my inflammation is optimal. Surprise, surprise. These are strong results. Thank you very much, Do Health. I also took the test to look a little deeper at things that you can't see on the outside, like testosterone, glucose levels, cholesterol, even my biological age. And then this is the bit that matters, a personalized plan for what to actually do about it. So in the next four months, I know that I can improve my results because this isn't just about your next race.
10:52It's about long-term health. Go to dohealth.co forward slash untapped and use code untapped. I'm competitive, you know that, so go and find out your numbers and come and tell me how you get on. On top of that, we've got a couple of beasts here from Sockany. So this is Stephen Scullion's favorite shoe for speed. Stephen is a good friend of the show and a good friend of mine. he's coaching me to get faster this is the Sorkinie Endorphin Elite Pro 2 quite the mouthful I know I've only ever worn this once uh you'd probably want to listen to Stephen Stephen when he used to be a bit lighter than he is now would race in this shoe he said this shoe is second to none so again I'm not trying to make weight the kind of central uh discussion point of all the shoes but I do think it makes quite a big difference right if a shoe is soft or firm or responsive or springy, your weight will have a material impact on how that shoe operates when you are running in it.
11:51So I think for the lighter athlete, I hear incredible things about this shoe. I hear amazing things about some of the pumas. This for me, I took it out once. I did put some pace through it. I really hammered it. It was around a time that I was not feeling great in myself. My body wasn't great. I had some issues with my shins and they did flare up. I'm not saying that it had anything to do with this particular shoe, but I did notice that it is pretty soft. Like it's very springy, very soft. And so when I run in this shoe, I kind of feel that when my weight pushes through the front of the shoe and I go to try and get that kind of snap out of my toe to really push off and exert some speed into the run.
12:38I felt it was a little soft for me. Same deal with the Sorkinny Endorphin Elite 3. So I was on a shoot and this shoe was kicking around and the wonderful PR lady said that I could keep the shoe. It's a similar thing. It is slightly more responsive than the two. It is a very, very, very fast shoe. But as far as I'm concerned, I get more stability from the Adidas Prime X3. I just feel like, you know, if we're using the analogy of a train being on a track, I feel safer, faster and better off for wearing, in my opinion, the more stable Adidas shoes. So I think the tech from Sockney is incredible. So far, I have got more out of the Prime X3.
13:32And then I've probably covered the most miles of all in this Adidas Agravic Terex trail shoe. Again, the sole continental. Project 7 marathons were done in these. the desert 30 marathons in 30 days were ran in these and snowden all six sides in 24 hours were just conquered in these these are all round great they're not for a marathon effort a fast marathon road effort they're not for a fast 5k they're not for a 10k you very much want to be going a little bit off road for this to make sense you'll see the the bottom of the shoe is quite grippy it has an insane amount of grip. Like literally you can run over smooth, wet rocks wearing these things and feel like you're running on, you know, beautiful, fresh tarmac in the sun.
14:29You know, as far as stability goes, they're not the greatest. They don't have a huge amount of kind of ankle support. But if you are off-roading and you're anywhere out in the open, they're light, they're durable and they offer a little snap in the foot for those times when you want to go that little bit faster. They're kind of semi-plated so I wouldn't call them a super shoe but they're absolutely an evolution on say a Vamero you know so if you're covering many miles and you're slightly off the beaten track I would always go Adidas Agravic Terex and there we have it. that is the review of some of the shoes that I have loved and used over the last few years if you like shoe content and want to hear us talking more about shoes you needn't have me do it listen to some of our guests we've had Alistair Brownlee, Stephen Scullion, Hugo Fry and Alfie Manthorpe go into deep detail about all of the shoes that they know and love and funnily enough they're all different so I think shoes are very much a personal thing listen to those episodes if you haven't already.
