Sure, let’s dive into the comparison between the Nike Pegasus 37 and the Structure 23. Please feel free to share the details, features, pros, and cons of each shoe.
Nike Structure 23
Erase all your current knowledge regarding the Nike Structure series. The Structure line used to exude a sense of firmness and rigidity. Softness was foreign to it, and I never truly found solace in wearing this shoe due to its unforgiving nature.
However, the Structure 23 heralds a complete reimagining of the series, and I must admit my appreciation for the new direction Nike has embraced. Prior iterations of the Structure emanated stiffness akin to an unyielding timber plank, yet the Structure 23 brings a refreshing joy to running. Should you be in search of a shoe akin to the Structure 22, prepare yourself for a disappointing contrast with the Structure 23.
Gone is the era of the traditional stability running shoe marked by a rigid journey and an intensified medial support. Still, it remains an emblem of stability and lightweight pronation, boasting remarkable adaptability and resilience.
It encompasses all the comforts tailored for enduring long distances that were once exclusive to the Vomero line prior to its 14th rendition. These include a sumptuously snug upper, an exceptionally enduring outsole, and a tender midsole replete with profound cushioning.
Nike Pegasus 37
Anticipation was widespread for the release of the Nike Pegasus 37, capturing the attention of many. The Pegasus lineage boasts an extensive and dedicated following. Spanning an impressive 37 iterations, it’s undeniably remarkable.
Curiosity abounded as individuals eagerly awaited the assessment of how the 37th version, featuring its fresh midsole, somewhat novel upper, and a slightly revamped outsole, would manifest in terms of sensation. The key inquiry revolved around whether it would uphold the standards set by its Pegasus predecessors, or potentially exceed them.
Specs
The Pegasus 37 tips the scale at 9 ounces. Its heel-to-toe drop measures 10mm, boasting a stack height of 24mm in the heel and 14mm in the forefoot.
In contrast, the Structure 23 registers at 10.2 ounces. For the men’s variant, the heel stack height is 22mm, accompanied by a forefoot height of 14mm, resulting in an 8mm heel-to-toe drop.
The women’s version, on the other hand, features a heel stack height of 20mm and a forefoot height of 13mm, yielding a 7mm heel-to-toe drop.
Notably, the Pegasus holds a slight advantage in weight over the Structure 23, yet the Structure boasts a more modest heel-to-toe difference.
When placed in context with previous iterations, the Pegasus 37 has undergone a marginal increase in weight and a 2mm boost in stack height, which added to the overall comfort.
For a daily trainer, the Pegasus 37 exhibits a slightly elevated stack height. Although I typically lean towards the 6 to 8mm range, the 10mm differential of the Pegasus did not pose any discomfort.
Who Are The Pegasus & Structure For?
Nike Structure 23
If you happen to be an avid enthusiast of Nike products and seek a blend of remarkable comfort along with a touch of support and stability, I strongly recommend exploring the Nike Structure 23.
This iteration marks a commendable advancement over its predecessors.
Over the span of numerous years, the Nike Zoom Structure has consistently maintained its stature as the favored choice among Nike’s selection of stabilizing running shoes.
How does the Structure 23 offer stability?
Many runners tend to veer away from stability shoes due to the common association with rigidity, weightiness, and an uncomfortable arch sensation.
Hence, Nike invested considerable effort in crafting a shoe that circumvents the sensation of pronounced underfoot support.
While not explicitly marketed as a stability shoe, the Structure 23 indeed offers a notable degree of stability despite lacking a firmer wedge or traditional medial post. This achievement can be attributed to two primary factors:
Firstly, the design encompasses a midsole that cradles the foot, accompanied by lateral railings that facilitate centered transitions during movement.
Secondly, the wide base of the midsole provides a sense of groundedness during foot strikes, regardless of the landing position.
Distinctive support is evident on the medial side of the midsole, which is more prominently built up beneath the arch. This reinforcement offers a discernible level of support without any intrusive sensations.
Although the densities of the medial and lateral sides are uniform, the medial wall stands taller. Additionally, a degree of structural reinforcement has been introduced, resulting in a subtle firmness while retaining the same foam composition.
The heightened cushioning on the medial side effectively curbs inward foot rolling by mitigating mild overpronation tendencies.
In summary, the Structure 23 serves as Nike’s counterpart to the Ultra Boost ST, combining substantial cushioning with a fortified medial side. It not only assists those with mild overpronation but also extends its benefits to neutral runners as their feet experience subtle inward collapse towards the conclusion of a run. Furthermore, the robust heel counter enhances overall support and meshes seamlessly with the shoe’s attributes.
Nike Pegasus 37
Designed with neutral runners in mind, the Pegasus stands as a road running shoe, tailored to offer a responsive and luxuriously cushioned running experience.
Upon subjecting the shoe to the twist test, its neutrality becomes resoundingly evident. In fact, the level of neutrality surpassed my initial expectations, which is noteworthy considering the slight increase in stack height by a few millimeters.
Midsole
Nike Structure 23
The standout feature of the shoe lies in its meticulously crafted midsole design. This midsole achieves a remarkable balance by delivering an exceptionally plush and cushioned sensation, all the while maintaining an impressive level of stability.
In fact, the cushioning sensation is so indulgent that it surpasses the softness of various daily trainers, including the Pegasus 37, the Miler, and the Vomero 14. It even outperforms many maximal cushion trainers, like the Brooks Glycerin and the Hoka Bondi.
However, it’s important to note that this plush cushioning doesn’t translate to the same level of energy return as exemplified by the ZoomX technology, for instance.
Where It Shines
Interestingly, Nike has chosen not to explicitly disclose the specific name of the midsole foam. There’s a possibility that it’s a novel foam variant, but its feel is reminiscent of the Lunarlon foam employed in the Vomero versions 10 through 13.
Nike’s approach with the Structure 23 contrasts starkly with their strategy for the Vomero 14. Instead of pushing for heightened speed and firmness, they’ve opted for a slower and softer dynamic with the Structure 23.
The abundant sinking cushioning and the flexible forefoot combine to create a scenario where accelerating the pace in the Structure 23 becomes challenging. It becomes clear that expecting anything beyond an easy pace might be stretching its capabilities.
On the flip side, the Structure 23 truly shines during extended runs or leisurely recovery sessions. It comfortably handles distances ranging from 15 kilometers to the marathon distance.
Personally, I’ve developed an affinity for the Structure 23 in the context of voluminous training and lengthy weekend outings. In this regard, it performs a role similar to that of the Saucony Triumph and the Hoka Clifton.
Nike Pegasus 37
The era of the long-standing Cushlon foam that adorned the Pegasus for numerous years has come to a close. Presently, Nike’s renowned React foam takes the reins.
The Nike Pegasus 37 boasts a full-length React midsole, complemented by a slight Zoom unit situated around the forefoot. React manages to strike an appealing equilibrium between firmness and cushioning.
React has demonstrated its durability over time, implying that the midsole is likely to endure a significant number of miles.
Consequently, the shoe offers substantial cushioning and insulation from the terrain. However, it’s worth noting that this iteration of React foam doesn’t quite mirror the sensation of its initial iterations.
While many appreciate React foam, it’s important to acknowledge that, especially in smaller sizes, it can bear a noticeable weight that’s generally manageable.
On the contrary, individuals with larger feet or those who possess a more robust running build might find the React midsole uncomfortably weighty.
In conclusion, I hold a favorable view of this midsole. While it may not be my personal favorite, it remains a dependable choice that reliably fulfills its intended purpose.
Zoom Air Unit
Both the Nike Pegasus and Structure have a Zoom Air pocket in the forefoot.
Nike Structure 23
Positioned at the forefront of the Structure is a Zoom Air pocket, strategically placed to deliver a responsive cushioning sensation and enhance the overall running encounter.
It’s important to note that this Zoom Air pocket differs from the tuned-up version found on the Pegasus; the Structure’s implementation maintains a distinct approach.
Nike Pegasus 37
The incorporation of the Zoom unit undeniably contributes to a satisfying propulsion sensation upon toe-off.
Transitioning from the React Miler, I harbored reservations about adapting to this shoe. However, the Pegasus presented a notably softer disposition, and the influence of the Zoom Air pocket was palpable during push-off.
What further piques interest regarding the Pegasus’ Zoom Air unit is the distinct setups for men and women. Notably, the women’s version boasts a lower psi (15 psi) compared to the men’s (20 psi) within the Zoom unit, yielding a slightly softer and more cushioned feel.
The rationale behind this differentiation stems from Nike’s discovery that many women seek a subtly softer and more energetic forefoot experience.
Interestingly, I’ve encountered individuals who have experienced both the men’s and women’s Pegasus versions, and they tend to prefer the softer sensation of the women’s model. An intriguing tidbit indeed.
While the Air pocket doesn’t render the Pegasus overtly responsive, it certainly lends a supporting influence throughout the gait cycle, albeit in a nuanced manner.
Upper
Nike Structure 23
The predominant theme characterizing the Structure 23’s upper is an indulgent plushness. This upper exudes an opulent comfort that would seamlessly blend with the Vomero’s profile.
In fact, it evokes strong memories of the Vomero 11, albeit devoid of the Flywire cables that were present back then.
Replacing the Flywire cables, you’ll find supple mesh panels spanning the midfoot area, their transparency evident through the perforations.
Regardless of your pace, distance, or intensity, this shoe effectively tailors its support to your movements. It provides a well-ventilated support extending across the forefoot and midfoot regions.
However, it’s worth noting that the Structure 23 tends to run warm, mainly due to the inner sleeve and the abundance of padding throughout. Consequently, moisture absorption becomes a factor. Consequently, it’s better suited for cooler climatic conditions.
Tongue, Lacing, Heel
The tongue boasts a discernibly increased thickness when compared to the Pegasus, enhancing the overall sensation of the lacing that secures the foot snugly.
Both the tongue and the heel cup feature an exceptionally soft texture, amplifying the overall comfort during the running experience. This alignment contributes to a seamless fit that eliminates any potential discomfort.
An external heel counter with a robust woven construction extends into the midsole, offering a resolute fit that effectively immobilizes the foot.
This reinforced heel cup, characterized by its stability and firmness, furnishes outstanding support during your road endeavors, steadfastly anchoring your heel in place.
Noteworthy is the pronounced cushioning within the heel region. The cushion’s precise placement translates into impeccable shock absorption coupled with a responsive feedback.
As a result, the upper exudes a notable thickness, and the generous heel cushioning engenders a sensation akin to the Pegasus. However, the distinction lies in the heightened stability present in the heel area, setting it apart from the Pegasus in this regard.
Nike Pegasus 37
The upper features a transformative aspect with its translucent mesh construction, marking a significant enhancement to the Pegasus lineage.
While retaining a notable thickness, the mesh exhibits a pleasant breathability, though not the most breathable among the shoes I’ve tested. Its soft material contributes to a comfortable fit for the foot.
The toe box is adequately wide, offering ample room for toe splay – a feature that particularly resonated with my foot shape.
The Flywire cables have been replaced by adaptive bands that conform to your foot’s dimensions, delivering a combination of comfort and midfoot lockdown.
Nonetheless, an issue arises when the shoe encounters moisture, as it tends to become notably heavy when wet. Therefore, it’s advisable to avoid venturing out in the rain with this particular model.
On the whole, the upper presents a commendable offering, characterized by a sufficiently wide toe box. Even for individuals with broader feet, opting for the standard width should yield a perfect fit and function seamlessly.
Tongue, Lacing, Heel
The tongue employed here can be best described as a standard Nike tongue, a design that has surfaced across a multitude of their shoes.
It’s gusseted and displays a relatively thin profile. There exists a minor degree of padding around this area, though overall, the padding is quite minimal.
One positive aspect is the additional material on the tongue that wraps around the inner ankle. This element contributes to a snug fit around the foot, enhancing the overall experience.
The lacing system follows a relatively standard design, accompanied by extra loops to secure the laces in place. While functional, it’s worth mentioning that these loops, while not necessarily detrimental, might add a bit of superfluous weight – an aspect that could have been potentially addressed with a standard eyelet chain.
Nonetheless, this lacing setup doesn’t impede effective lockdown in the Pegasus 37.
The ankle collar embodies a medium level of plushness, a balance that aligns well with my preferences. The padding neither veers too thick nor too thin, extending consistently around the entirety of the collar and down into the shoe.
To facilitate easy entry and exit, a slight heel flare is incorporated, allowing for smooth foot movement.
Size
The Structure 23 fits true to size and has a deep spacious forefoot. Also, for me, the Pegasus 37 is true to size.
The overall fit in the Structure is nice and wide and feels more like a Nike Miler in terms of the fit of the shoe. And that’s a big positive over the Nike Pegasus 37.
Outsole
Nike Structure 23
The Structure 23’s outsole showcases a robust construction, featuring a thick layer of durable rubber that envelops the entire surface. The heel area is reinforced with harder carbon rubber, while the midfoot and forefoot utilize blown rubber.
This strategic utilization of materials, particularly the Duralon rubber, significantly enhances the shoe’s durability, ensuring an extensive lifespan.
The outsole exhibits a commendable level of flexibility, imparting a sense of control that adeptly adapts to your individual running style and the nature of the terrain.
Additionally, the presence of a lateral crash railing contributes to effective impact absorption, enhancing overall stability.
Nike’s design approach is rooted in insights gathered from numerous runners, culminating in the strategic placement of the crash pad at the heel. This feature offers enhanced cushioning during heel-to-toe transitions.
To sum up, the Nike Zoom Structure 23 delivers an amalgamation of supreme comfort, a secure fit, and remarkable shock absorption, culminating in a comprehensive package.
Nike Pegasus 37
Nike has heavily integrated Duralon blown rubber into their design, along with introducing an updated waffle-style outsole pattern that harkens back to a classic aesthetic.
The lateral side of the shoe features the familiar crash rail that’s a hallmark of the Pegasus lineup.
I find the traction on this shoe to be commendably reliable, consistently preventing any concerns about slipping or instability.
Unlike some rubber compositions that can lead to an overly firm and stiff ride, the Pegasus manages to strike a different balance.
Notably, the outsole hosts rather deep lugs, a feature that stands out despite the Pegasus not being a dedicated trail shoe.
A prominent characteristic of the Pegasus 37 is the extensive decoupled groove running across the outsole. This particular design contributes to an added trampoline-like sensation, especially for those who tend to strike with their heels.
For heel strikers, the presence of the decoupled heel can certainly be appreciated, further enhancing the overall experience.
Issues
Nike Pegasus 37
There’s a couple of things about the upper of the Pegasus that kind of ended up being an issue.
Shallow around the ankle
The initial aspect to highlight is that the Pegasus exhibits a relatively shallow configuration within the vicinity of the heel counter. This design characteristic translates to ample space around the ankle bones.
It felt like my ankle was barely in the foot and I did struggle with heel slippage.
Heel Slippage
Due to the shallowness of this particular segment of material, during the landing and push-off phases, I noticed a sensation where the shoe’s back seemed inclined to move backward while my heel seemed to want to come out.
Despite this consistent rubbing motion along the back of my foot, I encountered no adverse effects such as red marks or blistering. However, I must emphasize that the overall sense of security was lacking.
On a positive note, I managed to mitigate this issue by utilizing the extra eyelet provided. Additionally, I found solace in the fact that the forefoot of the Pegasus offered a notably comfortable experience.
I am aware that some individuals have encountered difficulties with heel slippage in this shoe. I am genuinely interested to know if you’ve encountered similar midfoot-related challenges.
Weight
In my opinion, there’s a definite need for the Pegasus to undergo a weight reduction. Whether achieved through modifications to the React midsole, trimming down the substantial outsole, refining the upper construction, or even minimizing excess eyelet holders, shedding some weight is crucial.
By addressing this aspect, the Pegasus has the potential to transform into an entirely different and groundbreaking entity within the realm of running shoes.
Final Thoughts
Nike Pegasus 37
To conclude my impressions of the Nike Pegasus 37, I find it to be a favorable choice – a reliable and robust daily trainer.
For those seeking a versatile option that can effectively cover all bases within their running shoe collection, the Pegasus 37 stands out as a solid contender.
Furthermore, if you’re inclined to increase your pace, the combination of React foam and the Zoom unit allows for that transition without issue.
Lastly, the Pegasus notably excels as a suitable choice for prolonged periods of standing, underscoring its comfort and functionality in various scenarios.
Nike Structure 23
While the Structure 23 may not rank as the lightest or most breathable option available, its performance shines during the winter months, making it a reliable choice for that period.
And that concludes the comparison between the Nike Pegasus and Structure.
