The Nike Air Zoom Structure 25 is designed to provide reliable support for daily runs, particularly those at a comfortable pace. It incorporates a fresh Cushlon 3.0 midsole and a forefoot airbag, although its energy return is not particularly impressive.
In comparison to its predecessor - the Structure 24, it possesses a more classic stability trainer feel due to its noticeable arch. Despite its unremarkable ride, this shoe remains steadfast and long-lasting, making it an exceptional investment at its affordable $140 price point.
Who should or shouldn't buy Structure 25?
If the Pegasus 40 doesn't provide the stability you seek or the Infinity RN4 exceeds your budget, then the Structure 25 presents itself as a viable alternative.
If you're looking for a trainer that offers support without the feeling of a stability shoe, the Structure 25 is not the right choice for you.
Nike Structure 25 Brief Review
Nike recently made the decision to discontinue their Structure series and instead promote their Infinity Run series, a stable neutral trainer. However, it seems that Nike recognized the continued demand for a stability trainer. After a few years without the Structure, they reintroduced it as the Structure 23, a significantly altered version.
The Structure 23 provided a comforting and balanced running experience, deviating from the traditional stability trainer. After thoroughly examining both the Structure 23 and 24 (with the latter being an update solely focused on the upper), I concluded that these iterations marked the pinnacle of the Structure series. They offered remarkable stability and support, without compromising on a rigid ride or discomforting arch sensation typically associated with stability trainers.
In terms of popularity, the Structure series falls far behind the Pegasus and Infinity. Personally, I favor the Structure over both the Pegasus and the Infinity due to its well-padded upper and substantial cushioning. However, it seems that many runners still perceive the Structure as a classic, traditional stability trainer.
Unlike last year, where there were no revisions made to the Structure, this year brings us a completely transformed edition. The latest iteration sheds off a mere 0.2 oz (6 g) in weight compared to the Structure 24. Its heel measures 37 mm, while the forefoot measures 27 mm. Remarkably, the price of this revamped model remains at $140, making it more affordable than the typical mid-range daily trainer.
First Impressions of Nike Structure 25
Upon my initial exploration of Structure 25, I couldn't help but notice its remarkable resemblance to a stability trainer, surpassing its two predecessors. The presence of a distinct arch sensation, reminiscent of Structure 19, became apparent; however, it did not induce any pain or discomfort.
During my initial sprint session, I noticed that the Structure 25 was not as responsive as I had hoped. Its performance was somewhat lackluster when it came to increasing speed. Comparatively, the Structure 24 had a softer feel, but the Structure 25 provided better support thanks to the elevated midfoot section at the arch.
From the moment I slipped my foot into the shoe, I immediately sensed the signature airbag cushioning beneath the front of my foot. True to the Structure series, this feature provided a familiar and comforting sensation. Remarkably, the shoe delivered instant comfort without requiring any time to adjust or "break in".
The Structure 25 brought to mind the Infinity Run 3 shoe, with its similar features of heel clips and noticeable arches. However, the Structure 25 offered a firmer sensation compared to the Infinity Run 3.
The Pegasus 40 came to mind as it shared similarities with the mentioned item - both feature sturdy rides and tough outsoles, along with forefoot Zoom airbags.

The Structure 25 boasts a classic design with a cozy, cushioned upper that provides both comfort and warmth. While it offers slightly less padding compared to its predecessor, the Structure 24, it remains better suited for cooler climates rather than tropical ones. Personally, I find it incredibly comfortable, to the point where I confidently wear it for casual outings.
The tongue is cushioned and lacks a gusset, resulting in a minor sliding sensation that is not bothersome. Although there are double eyelets in the first row, I personally never utilized them since the shoe's secure fit is exceptional even without tying a runner's knot.
The shoe fits true to size, similar to other Nike running shoes, and has a slightly narrow feel. To maximize comfort, I prefer wearing thin socks with it as thicker ones tend to make it feel too warm.

As soon as you slip into the Structure 25, its ride becomes instantly familiar, reminiscent of the Pegasus and Infinity series. The Nike Zoom Air trainer sensation is unmistakable, ensuring a predictable and comfortable experience from the get-go.
The Structure 25 lacks an exceptional quality in its midsole foam, which has been replaced with Cushlon 3.0. The foam, however, lacks the innovative features of modern counterparts and instead resembles a foam that was popular six years ago. Consequently, the shoe lacks the desired level of bounce and energy return, resulting in a less enjoyable and captivating experience.
It excels when running at a leisurely pace, specifically below 5:30 minutes per kilometer. Personally, I struggle to increase my speed while wearing these shoes, so I reserve them solely for easy runs. They certainly lack the versatility of a training shoe.
The current standards dictate a firm ride. To achieve this, the foam surrounding the airbag beneath the forefoot must match its density, otherwise the airbag will become too noticeable and cause discomfort.
In Nike's range of trainers, the Structure 25 stands out as the ultimate support system. As someone with flat feet and a tendency to overpronate, I appreciate its stability, although the arch may be a tad overwhelming. While it does offer ample support for most overpronators, it seems better suited for runners with high arches.
This year's Structure introduces an innovative enhancement to its design - a heel clip that offers additional support. This notable feature has long been a trademark of the Infinity Run series. However, the latest iteration of the InfinityRN 4 has bid farewell to this distinctive attribute.
Nike claims that the Structure 25 possesses a rocker geometry, but in actuality, the flexibility of the forefoot undermines the sensation of the rocker. The shoe fails to provide a sense of energy conservation or effectiveness during extended runs, leading me to favor its use for shorter or medium-distance runs instead.
During a single training session, I attempted a 42 km run wearing these shoes. However, the experience was far from enjoyable. The footwear felt burdensome and slow, and I found myself exerting much more effort compared to when I wore other contemporary trainers with large, cushioned midsoles.
The primary advantage of the Structure 25 lies in its outsole, much like other Nike daily trainers. Constructed with a durable, thick rubber that covers the entire ground, it ensures longevity and resilience. Moreover, the outsole features raised lugs that enhance traction, even in torrential downpours.
I understand Nike's intention behind the Structure 25 and the latest InfinityRN 4: they aim to redirect runners who require support from the InfinityRN to the Structure, and vice versa.
The Structure 25 takes on the role of a stability trainer, distinguishing itself from its predecessors. With the addition of an extra heel clip, heightened arch support, and a firmer ride, it minimizes any inclination for leaning.
My preference lies with the Structure 24, as it lacks the pronounced arches commonly found in running shoes. The Structure 24 offered a sense of neutrality with its supportive features, whereas the 25 seems to lean towards being a stability trainer.
The Structure 25 is not going to remain a part of my running shoe collection. While it is reasonably priced and decent in quality, I am not particularly fond of its noticeable arch support due to my flat feet. I prefer running shoes that offer stability through a wider base or a supportive plate. Additionally, I find the overall running experience with the Structure 25 to be lackluster and unexciting.
To enhance the Structure series, it is imperative to enhance its midsole by incorporating Nike's top-notch ZoomX foam. This upgrade will significantly elevate the level of enthusiasm and thrill experienced while wearing these shoes.
