Nike Air Zoom Pegasus 37 VS 38: Good, Bad, and the Worst:

Now, I’ll clarify the differences between Nike Air Zoom Pegasus 37 and 38, if you don’t want to miss any point, make sure to read until the end.

1) Comfort:

Nike’s Air Zoom Pegasus 37 is the first model which features the brand’s up-to-date “React foam”, which they describe as the “most complete” foam. Due to this running in the Pegasus 37 gives you a sensation of elite footwear that provides the best in-shoe feel.


Moreover, the thicker airbag and midsole foam work wonderfully to provide deep, cushioning which will not be diminished after extensive use. 

However, the Pegasus 37’s forefoot-only Zoom Air unit and softer midsole provide responsiveness but because of this shoe’s overall stability can be compromised.

Conversely, the Nike Air Zoom Pegasus 38 is more cushioned, making it superior, however, the entire midsole is made of React foam, exactly like in the Pegasus 37, so the ride is just as quick and responsive. 

Furthermore, the padding on the ankle, collar, and tongue of the Air Zoom Pegasus 38 is substantially high which provides long-lasting comfort. As a result, it may appear bulkier than its predecessor, the good news is that it is somehow lighter in weight. 

Also, the pressurized air unit of Air Zoom Pegasus 38 is adjusted to a lower PSI in the women’s model to provide a slightly gentler and more forgiving ride. Nike made the changes to better accommodate women’s gait patterns to offer them the unmatched comfort they desired.

2) Popularity:

The Nike Pegasus 37 and 38 are popular among beginners and elite runners alike who engage in multiple activities frequently. However, the modified Nike Pegasus 38 got more fame among female celebrities and famous personalities as it has modern advancements.

3) Running:

The Nike Pegasus 37 features a smaller heel-to-toe drop, making it better suited to shorter, slower runs, but it lacks the support and stability needed for long, faster runs on various terrains.

On the other hand, Nike Pegasus 38 may not be the fastest running shoe on the market, but it’s flexible enough to allow you to keep pace when you need it so it is suitable for runners of all skill levels.

However, neither of these models should be considered for off-road running, as they lack technically advanced running shoes’ tread dimensions and other features. 

4) Walking:

The sole of the Air Zoom Pegasus 37 is strong and low to the ground and the arch support feels better when you walk, so you can use this model for longer strolls around town.

Alternately, the Pegasus 38 is comfier for walking because it has a lot of padding in the forefoot and the middle of the foot which offers a bouncy stride.

Another factor is, The Pegasus 37 performs poorly on walking surfaces that need pace, such as treadmills and tracks, whereas Air Zoom Pegasus 38 will work better on almost every surface.

5) Flat Feet:

Compared to Pegasus 37, the Nike Air Zoom Pegasus 38 prioritizes enhanced steadiness and pliability to accommodate a wide range of foot sizes and shapes so it will be a suitable option for those with flat feet.

This model also has a wider toe box that allows for natural toe splaying, a breathable mesh top, and a novel webbing system that connects the laces to a “fit band” for a snugger, more customized fit. 

6) Design:

The Nike Pegasus 37 bridges the line between a lightweight racing shoe and a supportive all-day trainer

Many of the top running shoe manufacturers are now offering their products specifically for men and women, rather than simply producing the same model in different sizes.

Nike’s Air Zoom Pegasus 37 has gender-specific Zoom Air units to address this issue, which stand out in the crowd. 

Additionally, its appropriate cushioning enables the foot’s return to the heel cup without restriction, thereby providing adequate support for the heel.

Moreover, a runner’s feet naturally bend at an angle, so its designers cut a deep groove in the forefoot rubber where the toes meet the rest of the foot for smooth movement.

Overall, it is a versatile shoe model that can be used every day, for any activity, but it is particularly suited for short- to medium-distance running.

Conversely, the design of Pegasus 38 is pretty much consistent with only a few changes from Pegasus 37, the most noticeable being an improved overall fit that will appeal to people who want a more robust sneaker with a wider forefoot. 

This model has also a larger, cushioned tongue which does a great job of keeping the foot safe from the pressure of the laces, also, the tongue is attached to the inner sleeve, which prevents the runner from slipping.

You can customize the fit of your Nike Pegasus 38 for everyday wear or a workout due to the redesigned lacing system, additional eyelets, and extra support across the upper.

The Pegasus 38 has proven useful for almost everything from routine training to tempo runs, transition runs, road time trials, and even races ranging from 5 kilometers to the half marathon.

What do customers think?

Testers loved how the midsole gave them a quick, exciting ride that didn’t ache their legs after a long run.

The outsole has been put through a lot of tests by some runners, including running on dirt roads, wet streets, and through mud it has performed amazingly well.

While the heel cup worked well for some of the buyers, others felt it could have done better keeping feet in place.

Also, runners warned that this shoe style is neutral, so don’t look at it if your feet need extra support and control of motion. Also, the base isn’t really wide, and the middle of the foot is less accommodating for different foot types.

Alternately, The Nike Air Zoom Pegasus 38’s ride is most often described as “bouncy.” 

The model has been praised by experts, who said things like, it helped propel them move forward and work best at faster speeds.

The top of the Pegasus 38 is soft and supportive, people remarked it hugs nicely around the foot and disappears once you start running. 

There are also suggestions that it stretches over time and needs slowly breaking in, so if it’s too tight now, it will be better after a few days.

The price tag hasn’t been talked about by many sneaker owners, which is a good thing however there are compliments like “reasonable price” and “very affordable”.

However, some reporters claimed that the shoes were uncomfortable to wear on hiking and that the soles developed structural defects very soon.

Conclusion: Which Is Better?

Nike Air Zoom Pegasus 37 and 38 both will perform well, but based on your preferences and how you run, one of them may be the best choice for you.

If you want a smoother shoe for medium-distance runs, get the Pegasus 37, its responsive midsole foam and technology provide a sophisticated ride, and the cushioning does not degrade over time.
