Nike Air Zoom Pegasus 37 Running Shoe Review

Nike has released the latest version of their very popular Pegasus running shoe – the Nike Pegasus 37 running shoe is now available.

This is an Air Zoom shoe – but it packs a big change too – there is now React foam in the midsole.

Nike Air Zoom Pegasus 37 Running Shoe – new for 2020. This is the successor to Nike’s Pegasus 36 shoe. What’s new? Read on to find out.

Our review pair has arrived – and we’ve put it through the paces. We’ll compare it to the Pegasus 36, as well as some other popular running shoes.

Here’s some of the styles that are available now from Road Runner Sports (we are an affiliate):

Let’s take a look.

Nike Air Zoom Pegasus 37 Running Shoe – Fit & Sizing

The Nike Air Zoom Pegasus 37 runs true to size.

A Men’s size 11 fits me perfect – and that’s my normal size.

The newest version of Nike’s Pegasus running shoe brings React foam to the game – and still has Air Zoom too.

The length is good, and the width is good.

This shoe is also available in a extra wide version – but we didn’t test that here.

From the top view you can see that the Pegasus 37 has the classic running shoe shape.

I don’t get any heel slippage in the Pegasus 37.

This is a neutral running shoe, with a 10mm heel to toe drop.

I recommend you order your regular shoe size for best results.

Nike Air Zoom Pegasus 37 Running Shoe – What’s New?

What’s new?

Lots. Let’s start with cushioning because that is such a key aspect of a running shoe.

First of all, the Pegasus 37 will use a forefoot cushioning unit (a Nike Air Zoom unit, of course).

Nike Air Zoom Pegasus 37 side profile
The stack height of this shoe is up a bit – by about 2 mm – that’s due to the React foam.

Didn’t the previous shoe have Air Zoom up front? Yes – but this unit is now twice as large as the previous unit.

The Air Zoom unit is also closer to your foot – meaning less midsole material between your foot and the Zoom air unit.

Nike Air Zoom Pegasus 37 insole
There’s a thin insole – but all the cushion magic happens thanks to the React foam and the Air Zoom unit in the forefoot.

Here’s another change – the air bag is tuned differently for men and women.

For men, there’s 20 psi of pressurized air, while only 15 psi for women.

Lurking within the forefoot is a double-thickness Air Zoom unit.

Nike’s testing indicated that women preferred the less firm support in the forefoot.

This shoe will include Nike’s excellent React foam as well.

I like React foam – it’s got great cushion, feels soft, but it also provides a crisp energy return or rebound.

It puts spring in every step.

And I’m happy to say the Pegasus 37 delivers on the React running shoe experience.

Nike Air Zoom Pegasus 37 side view again
Side view – the heel to toe drop is 10mm.

It does have good, crisp response – and you can really feel the difference in the forefoot with the double thickness Air Zoom bag.

Here’s some more good news – this shoe is available in regular and extra wide widths.

The regular width shoe is right in line with most of Nike’s men’s running shoes. A size 11 fits me perfect.

I have regular width feet – so I have not tested the extra wide model.

Not much has changed in the outsole – and that’s OK, because it works.

Nike Air Zoom Pegasus 37 - Side and Outsole
The outsole is tough – the black and red rubber is durable and provides good grip.

It also uses a new “fit band” that should adapt to the size of your foot for maximum comfort and security.

Close-up of the fit band – well, the part that integrates with the laces. This replaces Flywire and ensures a secure fit around the midfoot.

The last shoe used Flywire to help secure the shoe, but the fit band seems to be an adequate replacement.

The upper has been tweaked as well. It’s now a translucent upper that has “the look of speed” and is looks to be light and breathable.

Closeup of the mesh upper – it’s light and breathable. It looks good too.

Is it breathable? Check this photo to see daylight shining through the mesh – that’s usually the sign of a really breathable shoe.

That’s daylight shining through the mesh – this upper can BREATHE.

Closeup of the tongue. It’s thin and not bulky, but should provide adequate protection against lace bit.

Heel to toe drop? Still 10mm – of course.

The Pegasus 37 packs regular shoe laces, with an extra eyelet for a lace lock/runner’s loop.

Nike Air Zoom Pegasus 37 heel reflectors
From the heel view we can see the night reflectors. You’ll also see that the collar tapers off and away from your leg – just like in the 36.

A FlyEase version is available too.

What’s that? FlyEase is a zippered entry makes it easy to quickly get on and off. No-tie lacing secures the fit.

Let’s compare it to some other popular shoes, starting with it’s predecessor.

Nike Pegasus 37 versus Nike Pegasus 36 Running Shoe

The Nike Pegasus 36 was a popular running shoe.

It’s good looking, affordable, and worked well.

Nike Air Zoom Pegasus 36 - side by side
Nike Air Zoom Pegasus 37 versus the Air Zoom Pegasus 36. The older shoe uses Cushlon foam (not React) and has a full-length Air Zoom bag. It feels less cushioned.

What’s the big differences?

Well, as we mentioned there’s no React foam in the midsole.

The Pegasus 36 uses Nike’s regular Cushlon ST foam.

There is noticeably less cushion in the 36 – in my opinion.

Nike Air Zoom Pegasus 36 heel to heel
From this view, you can see the general shape of the two shoes is similar. The 37 does have a 2 mm higher stack height – due to all that React foam underfoot.

Secondly, the Pegasus 36 used a full-length Air Zoom bag.

So, that means the air bag runs the whole length (or nearly so) of the midsole.

When comparing them side by side the difference is noticeable.

The double thickness Air Zoom bag in the 37 feels much more cushioned.

All in all, it’s just a different feel. And to me, if feels like less cushioning than the Pegasus 37 has.

The other big difference is the use of Flywire to help secure the fit – rather than the fit band of the 37.

Does this make any sort of difference that you can feel?

Not to me it doesn’t

Otherwise, all the stats are about the same: drop is 10mm, fits true to size, etc.

The stack height is 2 mm less than the 37 – React foam shoes typically are “taller” than non-React. That’s just inherent to how React foam works, it seems.

And as such, the Pegasus 36 is slightly lighter than the 37. A Men’s Size 11 in the 36 weighs 10.3 ounces, where as the 37 weights 10.7 ounces.

Nike Air Zoom Pegasus 36 sole to sole
Outsole styles are similar – why mess with something that works?

For me personally, I’ll vote for the Pegasus 37. It’s got more cushion, feels more cushioned in the forefoot, and I like the extra cushion.

The fit band of the 37 replaces Flywire that was used on the 36. Both are adequate.

Nike Pegasus 37 versus Nike React Infinity Run Flyknit

Now, let’s compare to another lightweight, React running shoe – the Nike React Infinity Run Flyknit.

Nike React Infniity Run Flyknit side profile
The React Infinity Run has a rocker type of shape to the outsole. It’s a little more pronounced than that of the Pegasus 37.

This is a soft and ultra-cushioned shoe.

The React Infinity Run Flyknit is my go-to shoe for running on asphalt – I really like the cushion.

There’s much more React foam as compared to the Pegasus 37 – and that’s a difference you can feel.

Nike Air Zoom Pegasus 37 versus React Infinity Run Flyknit - side by side
Nike Air Zoom Pegasus 37 versus the Nike React Infinity Run Flyknit. Both are React shoes – but the Infinity has tons of foam – and no Air Zoom. Still, it’s soft as a pillow.

The forefoot feels more cushioned as well – because it’s solid foam rather than having a zoom air bag.

The Infinity Run is slightly heavier, probably because of all that foam.

A Men’s size 11 weighs almost 12 ounces, as compared to 10.7 ounces for the Pegasus 37.

The Infinity run has a very pronounced “rocker” shape to the outsole – but that’s not all that different from that of the Pegasus 37.

Nike Air Zoom Pegasus 37 versus React Infinity Run Flyknit sole to sole
React foam is not tough – and you can see Nike’s solution on both shoes – the blue/red/black is durable, grippy rubber. Both shoes should have a decent lifespan.

Nike claims the Infinity Run reduces the incidence of injuries.

I can’t weigh in on that – but I can tell you it’s a very soft, cushioned shoe – and these 47 year old joints appreciate that.

The other thing I really like about the Infinity Run – this is the Flyknit model with the woven, synthetic upper.

It’s thin, it’s light, and it fits like a sock. It’s very comfortable.

Nike Air Zoom Pegasus 37 versus React Infinity Run Flyknit side by side
Side by side.

I do prefer that over the Pegasus 37.

That said, only time will tell if Nike’s newest version of Flyknit is durable – that is supposedly one of the improved attributes.

The React Infinity Run is expensive at $160 – the Pegasus 37 is significantly cheaper.

How do you decide?

Want maximum cushion? Then go for the Infinity Run.

Nike Pegasus 37 versus UA HOVR Velociti 2 Running Shoe

Let’s take a look at a HOVR shoe from UA.

UA Velociti 2 Running Shoe heel view
Heel view – both shoes have reflectors.

HOVR is UA’s answer to React foam.

UA claims it gives “zero gravity feel”.

And indeed, the light-weight, cushioned support of HOVR foam bears more than a passing resemblance to React.

UA Velociti 2 Running Shoe side by side
Nike Air Zoom Pegasus 37 versus the UA HOVR Velociti 2 running shoe. HOVR is Under Armour’s answer to React foam – they claim it provides "zero gravity feel" – and largely it works just like React.

It cushions the impact, and rebounds crisply to give you spring in your step.

How does it compare to the Nike shoe?

It has noticeably less cushion in the forefoot – and that’s not something that I prefer.

UA Velociti 2 Running Shoe top view
From the top view, you can see the two shoes are similar shape and size – they are almost identical in weight too.

The Nike shoe has the Air Zoom unit up front – and the Velociti 2 just has foam.

Other than that, both are lightweight, neutral running shoes.

The upper on the Velociti 2 is light and breezy. I noted that my socks got very wet when walking through dewy grass – so there’s plenty of ventilation in that upper.

UA Velociti 2 Running Shoe sole to sole
More eery similarity in the outsole. Both have ample rubber for durable traction.

The UA shoe has an 8mm heel to toe drop, whereas the Nike shoe is 10mm.

The Velociti 2 does come Bluetooth enabled.

There’s a wireless transmitter somewhere inside – and once you download UA’s MapMyRun app you can quickly and easily sync up with your phone.

It’s easy – you’ll be up and running (pun intended) in seconds – after you download the app.

MapMyRun is a good app – it tracks your run’s route of course, but also stride, pace, minutes per mile – and more.

Nike has a similar device – but it doesn’t come with the shoe.

It’s a nice way to put some hard numbers to your workout – and it does help motivate you to go farther, or faster, or both.

Overall the Velociti 2 is a nice shoe.

For me personally though, it doesn’t quite have enough cushion in the forefoot, although the HOVR foam and other mechanisms are very apparent in the heel.

Nike Pegasus 37 Running Shoe – In Summary

This is a running shoe for the masses.

The Nike Air Zoom Pegasus 37 is a neutral running shoe, relatively light-weight and has a 10mm heel to toe drop.

The addition of React foam in the midsole, and the use of a double thickness Air Zoom bag in the forefoot make a noticeable improvement in the level of cushioning.

We look forward to running in these shoes – and they look good too!
