    Nike Air Zoom Pegasus 37: More air, more flair

    It's hard to not imagine a future, 50 years from now in which the Pegasus 87 has just been released and I'm telling my grandchildren how I remember running in the Pegasus 37. Such is the confidence I have that the Pegasus will still be around then.

    The Nike Pegasus has always been a very predictable shoe. Predictable in ride, fit, quality, and durability. That's why it's been so popular: you always know what you're going to get with the Pegasus.

     

    Nike-Air-Zoom-Pegasus-37.jpg

     

    Normally, every year the Pegasus has a “meh” release: only minor updates or changes so that Nike can keep their loyal Pegasus fanbase.

    This year is an exception because Nike has changed the midsole of the Pegasus from Cushlon, to React which is a huge change. Cushlon has been used since the Pegasus 27 of 2010. Midsole foams have made huge advancements since 2010, especially in the last 3 years.

     

    Nike-Air-Zoom-Pegasus-37-Tongue.jpg

     

    Not only has the midsole foam changed but the Zoom Air unit is now thicker — top-loaded, and only in the forefoot of the shoe compared to the full-length Zoom Air unit in the Pegasus 36. The airbag is now 10mm thick compared to 4mm in the Pegasus 36.

    The airbag in the forefoot of the Pegasus 37 is also gender-based. The men’s version is denser than the women’s version.

    I’ve never loved a pair of Pegasus shoes before. It’s always been a middle of the road trainer which doesn’t have much flair but also doesn’t do anything wrong.

    Some might see this as consistent but I’ve seen them as boring. Will this be the first Pegasus to make me fall in love with them and become a Pegasus fan?

     

    Nike-Air-Zoom-Pegasus-37-Upper.jpg

    First impression

    When I first took the Pegasus 37 out of its box, I was surprised at how thick and chunky the midsole was. Previous versions of the Pegasus have had an average, thin midsole but this one looked a lot thicker.

    The paint on the midsole had an iridescent glow to it in the sunlight which made the shoe look very futuristic. The lace eyelets and the midsole paint shift colours from metallic purple to green in the light.

     

    Nike-Air-Zoom-Pegasus-37-Toe-Box.jpg

     

    The first thing I noticed when I slipped the Pegasus 37 onto my feet was how squishy it felt underfoot.

    In previous versions of the Pegasus, one could hardly tell that it had a Zoom Air bag in it but in the Pegasus 37, it is very prominent in the forefoot. It made me want to walk around on my toes so that I could feel the squish.

     

    Nike-Air-Zoom-Pegasus-37-Fit.jpg

     

    I ordered the women’s version of the Pegasus 37 because the women’s version has the softer airbag in it: 15 PSI compared to 20 PSI in the men’s. I generally prefer softer shoes to firmer ones even if it comes at a sacrifice in responsiveness.

    I ordered my normal size in the women's version so I expected them to run small but to my surprise, it was the opposite. There was a bit too much space in the front of my toes and I could have gone a half size down.

    It could be that the women’s version runs slightly larger than the men’s but I think the Pegasus 37 runs longer than most shoes.

     Upper & fit

    The upper of the Pegasus 37 is made from a light mesh that feels thicker, smoother, and more padded than the upper of the Pegasus 36. Breathability is also not as good as in the Pegasus 36 so the Pegasus 37 runs warmer.

     

    Nike-Air-Zoom-Pegasus-37-Breathability.jpg

     

    The asymmetric tongue which is thin and flat is attached on the sides to the upper so no tongue slide occurs. I found the tongue to be slightly too short so it slipped downwards on runs.

    I would prefer it if Nike used a thick, longer tongue like the one on the Pegasus 35.

     

    Nike-Air-Zoom-Pegasus-37-Design.jpg

     

    The pointy heel counter of the Pegasus 37 flares outwards like previous versions of the Pegasus and on the inside of the shoe, there is padding to keep your heel in place.

    This heel setup didn’t really work for me as I experienced a small amount of heel slippage, even when I used heel lock lacing. This happens because the rear is too shallow and the heel counter doesn’t come up high enough.

     

    Nike-Air-Zoom-Pegasus-37-Heel-Collar.jpg

     

    Nike has gotten rid of the Flywire cables which looked like strings and have implemented new Flywire straps which are wide and not stretchy. These straps which are there for midfoot support and structure gave me a problem.

     

    Nike-Air-Zoom-Pegasus-37-Laces.jpg

     

    This first 10 kilometres of every run in the Pegasus 37 feel fine but then I start to get a hotspot on the medial side of my right foot, close to the toe box where the first strap starts. Nike should have made the straps softer and more stretchy.

    It takes some fidgeting with the laces at the beginning of every run to get the fit dialed in. The tongue is short so I couldn't make it too tight at the top or I'd feel the pressure. The midfoot and forefoot are narrow so I also couldn't make it too tight lower down.

     

    Nike-Air-Zoom-Pegasus-37-Comfort.jpg

     

    The fit of the Pegasus is narrow and long. The fact that it gave me a hotspot on my foot is proof that it is a really narrow fit and I don’t think going up a half size will help because then it will be way too long.

    The wide version might suit me better. The Pegasus 37 comes in narrow, regular, wide, and extra-wide versions.

     

    Nike-Air-Zoom-Pegasus-37-the-Upper.jpg

     

    Overall, I prefer the upper of the Pegasus 36. It gave me no hotspots or blisters, had a more accommodating fit, and was more breathable.

     Midsole & ride

    Cushlon was quite a firm foam so the change to React in the midsole is a welcome one.

    React feels slightly softer and a little more bouncy but it is still lightyears away from the responsive, springy TPU and Pebax foams. I can’t wait for the day that the Pegasus midsole is made from ZoomX foam.

     

    Nike-Air-Zoom-Pegasus-37-Cushion.jpg

     

    The Pegasus 36 was firm but the Pegasus 37 is a medium-firm density. The Pegasus 37 is too heavy for racing and too firm for long distances.

    It is best suited to faster runs (4 minutes 30 seconds per kilometre to 5 minutes per kilometre) at short to medium distances (5km to 20km).

     

    Nike-Air-Zoom-Pegasus-37-Performance.jpg

     

    It takes quite a fast pace in the Pegasus 37 to access the Zoom Air unit. At slower paces, the airbag doesn’t provide much responsiveness. When running in the Pegasus 37, I noticed that I tend to strike more on my forefoot because I subconsciously know that the airbag is in the front of the shoe.

    The Zoom Air unit is top-loaded this year, meaning it sits closer to the foot, right underneath the strobel lining. This is a great change and it feels like there are firm bubbles underneath my forefoot.

    It takes a lot of effort to get the Pegasus 37 up to a speedy pace and I really felt it in my legs as they began to tire during runs. It's certainly not an effortless ride.

    Although the React midsole is softer than in previous versions and the Zoom airbag softer in the women’s version, I still feel that the Pegasus 37 is not soft enough to be a truly versatile, everyday trainer. I would only choose the Pegasus 37 for distances below 20 km because of the lack of cushioning and the upper which causes a hotspot. 

    The Pegasus 37 is quite a stiff shoe as a result of the large Zoom Air unit in the forefoot. Even though the airbag has flex grooves in it, the Pegasus 37 still flexes behind the airbag, towards the middle of the shoe.

     

    Nike-Air-Zoom-Pegasus-37-Flexibility.jpg

     

    Stability in the Pegasus 37 is average. There isn’t much lean bias but the thick midsole makes it less stable than previous Pegasus versions.

    Transitions are smooth from heel to midfoot but as you get onto your forefoot, you can feel the Zoom Air unit underfoot. I would prefer it if Nike made the Zoom Air unit thick but full-length.

    The Zoom Air in the Pegasus 37 adds some sophistication to the ride character but it’s still not what I’d call a fun shoe to run in. It feels a little bit “plain vanilla” compared to other daily trainers such as the GlideRide with its rocker or the Infinity Run with its spongy-soft ride.

     Outsole & durability

    The outsole setup of the Pegasus 37 is amongst the most durable currently available. There are two types of rubbers used: harder, carbon BRS1000 rubber on the lateral crash pad and also softer, blown rubber on the medial rearfoot and forefoot areas.

     

    Nike-Air-Zoom-Pegasus-37-Outsole.jpg

     

    The rubber used on the outsole is very dense which is one of the reasons the Pegasus rides quite firm but also the reason why the Pegasus outsole is so durable.

    The lug shapes of the blown rubber are now waffle-shaped, a throwback to previous Pegasus versions. The last 4 versions had pentagon-shaped lugs. The shape of the lugs doesn't change the ride in any way.

     

    Nike-Air-Zoom-Pegasus-37-Durability.jpg

     

    There is a deep dimple under the centre of the heel which is new for the Pegasus series. This dimple makes the ride slightly more cushioned and responsive by allowing space for the heel to compress downward.

     

    Nike-Air-Zoom-Pegasus-37-Lugs.jpg

     

    Traction in the Pegasus 37 is great on dry and wet surfaces of all types.

    Durability is one of the reasons the Pegasus is so loved and the Pegasus 37 takes durability up a notch. The hard outsole rubber shows almost no wear after two weeks of testing the shoe, running in it every day.

    The React foam of the midsole is also durable as React doesn't lose much cushioning over the life of the shoe. There are also no signs of weakness on the upper.

    The Pegasus should easily last upwards of 1000 kilometres of running. The highlight for me is the super durable outsole which I wish all Nike trainers used.

    Comparisons

    Nike Pegasus 37 vs. Nike React Miler

    The Miler has a more comfortable, padded upper with a better lockdown and no heel slippage. The Pegasus 37’s midsole is firmer but it has the Zoom Air bag for extra responsiveness.

    The Pegasus 37 also has a more durable outsole but I would still choose the Miler over the Pegasus 37 due to its more comfortable ride.

     

    Nike-Air-Zoom-Pegasus-37-vs-Nike-React-Miler.jpg

    Nike Pegasus 37 vs. Nike Infinity Run

    Both uppers suffer from heel slippage but at least the Pegasus has double last row eyelets for heel lock lacing. The Infinity Run has a much softer midsole but is less stable.

    The Pegasus 37 has a more durable outsole. The Infinity Run wins with its squishy, more fun ride.

    Nike Pegasus 37 vs. Nike Rival Fly 2

    The Rival Fly 2 has a better upper with no hot spots. The Pegasus 37 has a softer, more responsive midsole with its thicker Zoom Air unit.

    The Pegasus 37 is better for longer distances with the Rival Fly 2 being lighter and better for short distances. I'd choose the Pegasus 37 with its more responsive forefoot over the Rival Fly 2.

    Conclusion

    If you're a hardcore Pegasus fan and you buy the new version every year, chances are high that you will love the Pegasus 37.

    For the first time in ages, the Pegasus has some flair. The 37 has a brand new React midsole which is slightly softer and more durable. It also has a new forefoot-only Zoom Air unit which is more than twice the thickness of the Pegasus 36 which makes the ride more responsive and softer.

    The upper of the Pegasus 37 is narrow but longer in the front of the shoe. It is smoother, more padded but warmer than last year's version. It caused a hotspot on the medial side of my foot so be careful of the width of the shoe when making your purchase.

    Pegasus 37 is a vast improvement over the Pegasus 36 but it didn't do enough to make me fall in love with the Pegasus series. I found the Pegasus 37 to still be too firm for long distances and not bouncy enough for a fun ride.

    I did however really enjoy the prominent, thick air bag in the forefoot so it's possible that I have developed a tiny crush on the Pegasus 37.

     

    Nike-Air-Zoom-Pegasus-37-Heel.jpg

     

    For the next version of the Pegasus, I would make the midsole out of ZoomX foam for extra cushioning and response, and keep the thick Zoom Air unit but make it full length so that transitions are smoother. I would also make the midfoot Flywire straps softer and more stretchy to improve the fit.

    I loved the ride of this. It's just got a really soft cushioning but also that Air in the front just gives you a little pop when you're out there running.

    I found that this was super sticky, super grippy.

    From performance to aesthetics, Nike really nailed this one. Similar to the Saucony Kinvara, I think you could use the Pegasus for daily training to speed work and even racing. If you’re looking for a shoe that can do it all, definitely give the Pegasus 37 a try.

    Nike nailed it in the marketing copy when they called the Pegasus 37 “a workhorse with wings.” I am sure I will be reaching for these shoes throughout the rest of the year. As long as you don’t mind a snug-fitting upper, I can safely recommend the Peg 37 as a top pick.

To improve rebound and cushioning, one of the refinements made to the Nike Pegasus 37 is the incorporation of a renewed Air Zoom unit. With this iteration, the Air Zoom pocket in the forefoot is twice as large as the shoe’s predecessors. 

Another augmented feature of the running shoe is the trimmed-down weight of the shoe’s React foam. Aside from preventing drag, the midsole technology has also been engineered to be more responsive and sturdy. 

For added oomph and to give the feeling of speed, the shoe presents a translucent mesh. It not only strives to appeal visually but it also serves a certain function. The redesigned upper is intended to keep the weight of the platform at an absolute minimum while maximizing ventilation. 

Situated at the shoe’s midfoot is an added technical element that is responsible for support and lockdown. This pertains to the fit band of the shoe, preventing unwanted shoe removal. 

The rest of the shoe’s components are carry-over design features from the series’ previous model. For instance, the Pegasus 37 still kept the waffle rubber outsole of its predecessor for flexibility and grip.

To offer runners an array of options, the Nike Air Zoom Pegasus 37 is available in medium, wide, and extra widths. This is applicable to both male and female purchasers. It is advised that before placing an order, trying on the fit of the shoe or going through user feedback first is best. This is to ensure that precise fit and size are secured. 

One of the components of the Nike Pegasus 37 that affects its fit is its mesh upper. It supplies an adaptive wrap around the foot, locking it in place. Complementing the mesh upper of the running shoe is the midfoot band. This aids in supplying maximum support and security while optimizing comfort. Lastly, the classic lacing system of the shoe, just like that of the Nike Air Zoom Streak 7, promotes a dialed-in, accurate lockdown.

One of the construction principles of the Pegasus 37 from Nike is to keep the bulk of the shoe at an absolute minimum. This is evident in the outsole configuration of the running shoe, exhibiting a waffle design in the forefoot. Aside from maintaining the lightness of the shoe, this outsole composition also allows for multi-surface traction. Moreover, with such outsole cuts, the shoe is equipped to have more pliability, promoting unrestricted foot flex. 

The running platform also exhibits an adjusted lug positioning. This supplements the waffle outsole of the shoe to help evenly distribute the shock during impact. 

Similar to the Nike Air Zoom Structure 22, the forefoot of the Nike Pegasus 37 is composed of Duralon rubber. It consists of a blown rubber compound that highlights grip and added strength. This enables the shoe to achieve peak performance on varied surfaces. 

Intended to further boost the high-strength qualities of the shoe, BRS 1000 rubber is also implemented. This component is made of carbon rubber which helps mitigate shock during impact. Because of its sticky traction, the BRS 1000 rubber encourages surefootedness.

One of the most hailed features of the shoe is its revamped midsole engineering. A staple to the Pegasus lineup, Nike’s React foam and Zoom Air are integrated. These two technical innovations work hand in hand to create a bouncy, well-cushioned ride. 

The Nike React foam is responsible for producing a springier performance and improved underfoot plushness. Because it maintains a featherlight profile, the added foam does not necessarily equate to added weight. Thus, comfort and responsiveness are heightened while minimizing drag. 

On the other hand, the forefoot compartment of the shoe sports Nike’s Zoom Air technology. Contrary to the shoe’s predecessors, the Nike Pegasus 37’s Zoom Air bag is twice larger. This construction is geared towards making a bouncier ride. It is also top-loaded closer to the wearer’s foot for augmented responsiveness.

Adhering to the ultra-light configuration of the shoe, the upper of the Nike Zoom Pegasus 37 is made of translucent mesh. This mesh material employs several perforations that are tasked with amplifying ventilation. It serves as the airflow system of the foot chamber, actively eliminating foot sweat and odor. Because of its flexible property, the mesh upper conforms to the natural shape and contours of the foot. This betters the lockdown and fit of the platform, preventing premature shoe dislodgement. 

In the midfoot of the shoe, a fit band is incorporated. This technical element allows for better fit and comfort, keeping the foot in place. It adapts to the size of the foot, allowing a customized wrap. 

Just like most road running shoes, the Pegasus 37 is furnished with a traditional lace-up closure system. It allows a snug, adjustable fit.

  • The Pegasus series is touted by Nike as “the shoe for every runner.” The first model of the collection was introduced in 1983. For 37 years, the Nike model has undergone major improvements to cement its reputation in the market. 
  • The women’s version of the Pegasus 37 flaunts a less pressurized Zoom bag composition. It only has a 15-psi Zoom pocket. This offers a less stiff underfoot feel. The men’s version, meanwhile, has a 20-psi Zoom bag. 
  • The women’s version of the shoe is available in four different colors: Pale Ivory/Barely Volt/Sail/Ghost, White/Aura/Metallic Silver, Champagne/White/Barely Rose, and Pure Platinum/Laser Crimson/Psychic Blue/Black.
  • The men’s version of the shoe is available in six different colors: Black/Valerian Blue/Spruce Aura/Ghost Green, Iron Grey/Particle Grey/Photon Dust/Light Smoke Grey, White/Pure Platinum/Black, Obsidian Mist/Black/Lotus Pink/Hydrogen Blue, Black/White, and Black/Olive Aura/Laser Crimson/Medium Olive. 
  • The global release of the 37th iteration of the Nike Zoom Pegasus lineup is on April 28, 2020.
