Nike Pegasus 38 | Analysis, opinion and review in English


Cambiar idioma

The Nike Pegasus series is probably the most famous in history. Since 1983, the year in which Nike introduced this sneaker to the market, it has been renewed annually. That means that in 2021, the model we have is the Nike Pegasus 38the latest iteration of this shoe with so much history behind it.

The Nike Pegasus 38 is Nike's training shoe, the one that claims to do it all. From light and long workouts to even offering a bit of speed on faster days. And all this for a price that, within what is the usual Nike range, is quite interesting. An everyday shoe that can do everything.

In its thirty-eighth version there are no major changes, which focus on the upper. Outsole and midsole remain unchanged compared to last year's Pegasus 37. Which is a good thing, as the main complaints from 37 users were focused precisely on the upper. So it's those changes that I'll focus on in the review.

Nike provided me with a pair of shoes to review. I've been using them with some regularity in my usual workouts, although not for everything as on fast interval days I've opted to use something with more energy return (the Nike Tempo NEXT%). But it has been "almost everything", because I've even taken them out on trails and trails..

I've been rotating the Pegasus 38 on my feet for a few weeks now, more than enough time to get to know them and adapt them to my feet. So I can now tell you all about what they have to offer.

  • React foam is always pleasant to use
  • Some more space for the fingers

Nike Pegasus 38, a much-needed upper change

The upper of the Pegasus 37 turned out to be quite poor and few users liked it for two main reasons: a too narrow forefoot that squeezed the toes (and 1TP10Could cause blisters) and a collar that did not support the foot as much as necessary, preventing the heel from locking in properly and making the shoe move around in the foot.

This is what Nike has tried to fix with the new upper. On first wear you can see that it is quite comfortable and that the materials used are of quality. Everything is quite soft, especially the tongue which is now longer but above all much more padded. We abandon that thin tongue that we had in the Pegasus 36, lighter and with a feeling of being more focused on a racing shoe or faster paces.

That thicker tongue helps protect the foot from lacing pressure. Also, because it is wider, it moves the foot slightly further back to help with heel lockdown.

The forefoot area is wider, leaving more room for our little toes. There is no feeling of being with the foot imprisoned. As I said at the beginning that was the main complaint of the Pegasus 37 users, a front part too narrow that besides not being comfortable podía cause blisters by chafing. In fact I stayed in the Pegasus 36 and never made the move to the 37.

However, not everything is perfect. The type of double mesh that Nike has used for these Pegasus, despite being comfortable and stretchy enough, I find it quite warm. This is something that is more easily seen now with the arrival of summer and high temperatures.

This double mesh system feels quite thick to the touch and is not overly breathable. If we add to that the thicker tongue the result is that we have a pretty warm shoe for winter, but I'm sure that running with it in hot areas you will find it lacking in ventilation.

Nike Pegasus 38 - Upper

Don't get me wrong, it is still a daily training shoe and is far from more specific running shoes such as the Vaporfly NEXT%2. In general all training shoes are going to feel a bit warm, but the Pegasus 38 maybe a bit warmer than its rivals. 

It is something to take into account whether you are going to use them in summer or ride with them in winter. 

Vaporfly midsole without changes or modifications

The problem with the Pegasus 37 was in the upper of the shoe, but the midsole worked quite well. It's all made with Nike's React foam - which doesn't have the reactivity of the ZoomX, but it's not as soft either - and it also incorporates a Nike Air unit in the forefoot.

React has a pleasant feel. It's not hard, but it's not overly soft either. But this foam is more comfortable than the Cushlon we found in the Pegasus 36. So there is more comfort and more protection, but at the same time it is loose enough to be able to move at medium-high paces.

Nike Pegasus 38 - React midsole

This change to React foam makes it a good candidate for training over longer distances. They are a good training shoe for half marathon or marathon, but perhaps they have lost the usual versatility of the Pegasus for shorter distances.

Of course, when necessary I have had no problem to speed up the pace and go under 4:00min/km to do some kind of interval, but these are not shoes that ask for speed. 

I have also had the opportunity to wear them on easy trail routes (roads and trails, no mud or aggressive descents), and the midsole is thick enough to filter out the small stones that we find on the road. At no time did I have the sensation of nailing any of them.

In the front part of the midsole is where we find the air pocket. This bag is somewhat larger than in previous models and is a good ally to absorb the blows of each step on the asphalt, offering at the same time a sense of thrust when taking off from the ground.

With respect to the "Airbag" there is a curiosity, and that is that the feel offered in the men's and women's models is different. According to Nike, women prefer a softer feel, to run more comfortably. Men preferred a harder feel. So the type of bag differs between the two models.

The sole on the Pegasus 38

The outsole is already very classic in the Pegasus 38. The design is the same as in the Pegasus 37 and practically the same as in the 36 and previous ones. It is a hard and resistant sole that allows to run for many kilometers without appreciating important wear.

Nike Pegasus 38 - Outsole

Obviously a hard sole doesn't cope well with tricky situations like wet asphalt, where it's certainly not the aspect where they shine the most. You can't have everything, I guess.

At the rear of the shoe, under the heel, there is an area where the midsole is visible. This opening saves weight and makes the heel softer as the foam can compress better in this area.

But as I said before I also wanted to test the Pegasus 38 on an easy trail route. Trails, some loose rock and dirt. But no mud or rock. In other words, a looser surface than asphalt but without complications or difficulties.

The Pegasus offered me enough confidence in traction, with no slippage even going downhill. Let's be clear, this is not a trail shoe, nor is it their primary use, but if you're going to mix asphalt with loose terrain or trails, podrue do it all with the Pegasus 38.

Nike Pegasus 38 review

Nike has updated the Pegasus 38 where it was most needed, as the upper of the 37 created problems for many users. Both due to chafing and lack of support in the heel area. 

Both aspects have been corrected, but my only complaint about the upper is that I find it hot. This is logically increased now that summer is about to start. But of course, I live in the south of Spain and what for me may be a hot shoe for someone else may have the appropriate point. And of course on cold winter mornings it will be much more pleasant than a more ventilated shoe.

The Pegasus 38 are true to their tradition. They are good in all aspects, but don't stand out in anything special. They are a good candidate as a training shoe, especially if you run two or three times a week and only want to have one pair of shoes (and they are not too expensive), these are good candidates.

If you run more frequently, remember to have more than one pair of shoes. After a run, the midsole needs some time to recover all its properties. In addition, if you have more training volume, you will probably need something faster for series days.

You may be wondering where these Pegasus 38s rank in the brand's range of sneakers. We have for example the Nike Infinity Run FlyKnit 2pod can also be considered as a training shoe. The Infinity is a more maximalist shoe, with more stability and more oriented to long runs.

But where the Nike Pegasus 38 works well is as a wildcard shoe for paces neither too high nor too low, quiet workouts or a bit more lively, they can even serve you for competition if you are not going to run under 4:30 min/km. 

If you are looking for a shoe that won't surprise you with chafing or discomfort after 10 or 15 kilometers the Pegasus 38 are good candidates. But don't look for new technologies or big changes, because this is not Nike's line where we will see this.

And with that... thanks for reading!

  1. Good analysis Eduardo, I really liked the video.
    I think that in the next sales they will fall... The current Pegasus 35 are coming to their end and these look very good.

    1. Both models are focused on the same type of use, but the Vomero in theory belong to a higher range, something more "premium". In their case, the higher price of the Vomero is justified by the use of ZoomX foam in the heel, but unless you are clearly a heel striker it is something that is not taken advantage of.

      Personally I like the Pegasus better, both for the feel (I have the Vomero 14, not the 15) and for the fact that I don't particularly like the ZoomX foam in the heel.

    1. I don't like to talk too much about the recommended weight of the runner. Mainly because I weigh 93kg and I've never had any problems regarding weight and shoes, apart from the fact that I obviously wouldn't opt for a classic flyer.

  2. Hello namesake, I am a police opponent and I have a NBalance Solvi V2 for medium runs (5.00 min/km) and a Pegasus 36 for faster runs (4.30 min/km) and series (3.30 min/km). What shoes do you recommend for the days of series and thus discard the NB. If possible without carbon plate as I do not know if I would adapt until October / November which is when would be the oppositions.
    Thank you and great job.

    1. I understand that the intention is to leave the Pegasus for medium and long runs and buy new ones for fast days and series, right? In that case I recommend the Nike Tempo NEXT%. They have a plate for stability, but it is nylon and not carbon. But you have no problem, you will adapt from the first day and you will appreciate the ZoomX from the first moment.

  3. Hi, I am currently training for half marathon I move at paces of 4:30 to 5:30 and currently train with the Propel V2 and I just got the new rebels for quality training days, I need to replace the Propel and I serve these pegasus or I will come better Infinity run Flyknit 2 or 880 of NB? Thank you.

    1. The Propel is a faster shoe than the Pegasus or especially the Infinity Run. But I understand that by incorporating the Rebel you are not looking for that freshness that the Propel can bring, but something more rolling.

      If you want something comfortable for long runs at a light-medium pace, I would opt for the Infinity Run for having something clearly different from the Rebel. I think it can be a good combination with the Rebel. The Pegasus have a "similar" concept to the Propel, but they lean more to the training shoe side than the mixed shoe side, which is where the NBs tip the scales.

      1. Thank you so much for the clear explanation!!!! I will try the Infinity and let you know my impressions!!! Greetings excellent your analysis, I'm a fan!!!!

  4. Hi, Eduardo!

    I would like to buy some Nike shoes, I have a dislocated kneecap and a month ago I suffered a stroke, so neurologists recommend me to walk a lot a day. I also go to the gym, so I was looking for a pair of walking or running shoes, good for walking on asphalt and that do not slip in the wet (because of the kneecap). I have looked at the React Miler 2. Which ones would you recommend? Thank you very much!

    1. The Nike soles are not exactly noted for their grip in the wet, although if it is for walking there is not much of a problem. It is more a matter of traction when running.

      The React Miler 2 is a shoe with more cushioning and outsole than the Pegasus. The configuration is also different, as they have a rocker shape, while the Pegasus have a more traditional configuration.

  5. Good afternoon, my name is Patricia mido 1.65 mts and weigh 107 kg, I reached 127 kgs, I had decided to buy Pegasus 38, but I'm hesitating because I heard in an advertisement, which is aconsrjada for a weight of 75 kg or 80 kg, that for more weight recommend the Gomero, podrías tell me if so, what I recommend, I'm just going to walk. I ask you if I podes reply by email. Thank you

  6. Hello I am hesitating between the pegasus 38 or the infinity run 2, it would be as unique shoes to quiet rhythms about 5, I have some for trail and others for asphalt, and I have to renew the asphalt, I have an asics columus 16 that I have not liked too much, I noticed them as soft or unstable, I do not know which would come to me better.

  7. Hi, I have always been a fan of the Pegasus, have the 31 and 35 and was thinking of getting the 38. The idea is to use it for Half around 1h25′ - 1h35′, and for Marathon +/- 3h30. I weigh about 70 kgs.

    1. In my opinion the Pegasus are a good training shoe, but not the best choice for marathon due to lack of cushioning. Maybe for half marathon it can work, but my choice for marathon would not be Pegasus.

  8. Hi, Eduardo,
    I wanted to ask you if you see this shoe suitable for just walking... I come from a Free 5.0 that are destroyed and that I used for walking or for the day to day, since I have a lot of lumbar lordosis and that is why I do other sports that are not running but I try to take care of my back permanently.
    I've tried the Pegasus in store and they seem very comfortable, maybe more than the Trail ones I've also seen. The Free have been good for me these years but I think that more drop will be better for me. Age is unforgiving (42 years old and 60kg by the way).

    Thanks in advance and best regards!

    1. Yes, you have no problem using them for walking and as you say they are quite comfortable shoes. If it is for walking on asphalt better the Pegasus 38 than the Pegasus Trail.

  9. Good morning,
    My name is Aleida, I am currently training for a half marathon, I bought the Pegasus 38 premium shoes and I have been running with them for a week, but sometimes I feel that they are not so light, I do not know if it is because they are new and I have not adapted well to them, what do you recommend?

  10. Hi I weigh 47 kilos and I want some shoes for marathon, so far in 10 kms and 21 I have used the react epic flyknit , the pegasus will be too heavy for me? Pace 5.15. Thanks 🙂

    1. The Pegasus are a model mainly focused on training, therefore they are cushioned but as you indicate the weight is not what you are looking for in this model, especially for a somewhat heavy upper. You can use them to train for the marathon and of course to run it, although it would always be advisable to do the race with something lighter and equally cushioned.

  11. Hi, I'm having a lot of trouble with my Pegasus 38...until this issue. They were my go to shoes for all the bottoms. These, at mile 6 they start to desperately burn the Silver on my feet. I thought it was my feet, I put back on the 37 I had, and I was able to run normally. So, in my case it's the shoes that are the problem. Now I don't know which shoes to adopt
