In the expansive and often expensive world of performance footwear, the search for a versatile, reliable road running shoe that won’t break the bank can feel like an unending marathon itself. We are often faced with a difficult choice: pay premium prices for cutting-edge technology, or settle for a budget model that compromises responsiveness and durability. For the casual runner, the gym enthusiast, or the professional who spends all day on their feet, the demand is simple—comfort, stability, and enough energy return to make the movement efficient, whether it’s the 5K track or the office floor.
The challenge intensifies when a runner identifies as “neutral,” meaning they need balanced cushioning rather than heavy corrective support. A poor choice here leads to rapid fatigue, unnecessary strain on the joints, and ultimately, injury. We initiated our extensive testing of the Under Armour Charged Assert 9 Running Shoe precisely to determine if it could meet this crucial need, offering a genuine blend of protection and responsiveness at a highly competitive price point. The question isn’t just whether it performs, but whether it provides authentic value and longevity.

Choosing Your Foundation: What to Consider Before Buying a Road Running Shoe
A Road Running shoe is more than just an item; it’s a key solution for absorbing the repetitive, high-impact forces generated during forward motion on paved surfaces. The right shoe drastically reduces strain on the knees, hips, and lower back, enhancing training consistency and overall enjoyment. By utilizing specialized foam compounds and carefully engineered outsoles, these shoes ensure that energy is returned efficiently, minimizing wasted effort and protecting the body mile after mile.
The ideal customer for this type of product is someone facing high-mileage training or seeking a comfortable daily walking shoe, particularly those with a neutral gait pattern who don’t require aggressive pronation correction. These individuals benefit from a balanced platform that allows the foot to move naturally. Conversely, this shoe category might not be suitable for those who require maximum stability (severe overpronators), or those who prefer the minimalist, zero-drop feel of trail running or specialized speed shoes. For heavy runners or those with specific foot issues, alternatives offering higher density foam or specialized arch support might be necessary. For those seeking balanced performance in an affordable package, however, the technical specifications of the Under Armour Charged Assert 9 Running Shoe provide an interesting proposition.
Before investing, consider these crucial points in detail:
- Offset (Drop) & Biomechanics: The shoe’s offset, or “drop,” is the height difference between the heel and the forefoot (in this case, 10mm). A higher drop, like that found in the Under Armour Charged Assert 9 Running Shoe, tends to alleviate strain on the Achilles tendon and calves, making it appealing for heel strikers and those transitioning from traditional running shoes. However, runners focused on midfoot or forefoot striking might prefer a lower drop for a more natural, ground-contact feel.
- Cushioning Capacity & Responsiveness: The quality of the cushioning system dictates both the protection and the energy return. For the Charged Assert 9, the crucial component is the Charged Cushioning® midsole. We need to evaluate whether this compression molded foam lives up to its promise of being responsive, durable, and offering effective impact protection, especially under high-mileage loads.
- Materials & Durability of the Upper: A running shoe’s upper must balance breathability with structural integrity. The Charged Assert 9 utilizes a lightweight mesh but incorporates durable leather overlays strategically placed to secure the midfoot. This combination is designed to lock the foot in place and prevent excessive internal movement, a vital factor for long-term comfort and blister prevention, but its longevity needs intense scrutiny, particularly regarding the mesh material itself.
- Ease of Use & Maintenance: Road running shoes, especially budget-friendly models, must be easy to slip on, lace up, and maintain. The traditional lace-up closure of the Assert 9 ensures a precise fit. Maintenance largely involves keeping the mesh upper clean and ensuring the EVA sockliner doesn’t retain too much moisture, preventing odor build-up—a simple yet critical aspect of long-term satisfaction.
The intersection of these factors determines whether a running shoe is merely adequate or truly exceptional. Now, we turn our attention to how the specific technology within the Under Armour Charged Assert 9 Running Shoe performs against these benchmarks.
While the Under Armour Charged Assert 9 Running Shoe is an excellent choice for a neutral daily trainer, it’s always wise to see how it stacks up against the competition, especially if you have specific biomechanical needs.

Initial Examination: First Impressions of the Under Armour Charged Assert 9 Running Shoe
Unboxing the Under Armour Charged Assert 9 Running Shoe immediately confirms its core design philosophy: lightweight versatility. At a package weight of 1.65 pounds for the pair, the shoes feel remarkably airy in hand, signaling their intent as a nimble daily trainer rather than a heavily armored maximalist option. The visual aesthetic, particularly in the Downpour Gray, is subtle yet modern, utilizing the 3-color digital print mesh upper which gives it a textured, appealing look.
Our first impression centered around the mesh upper. It is instantly evident that breathability is a priority here. The lightweight material is soft and pliable, promising excellent ventilation, crucial for warmer climate running or prolonged gym sessions. However, the standout feature is the integration of the durable leather overlays. These overlays are strategically placed over the midfoot and eyestay area, providing structure without adding significant bulk. We found this design approach cleverly tackles the common issue of lightweight mesh offering poor lateral support; the leather truly secures the foot in place.
Stepping into the shoe, the cushioning is firm but immediately comfortable. The EVA sockliner does an admirable job of providing soft, initial step-in comfort—a feature frequently overlooked in budget-friendly models. While the shoe maintains a substantial 10mm offset, it doesn’t feel overly clunky. Compared to heavier, more cushioned models currently dominating the market, the Charged Assert 9 presents itself as a classic, reliable workhorse, prioritizing responsiveness and a secure fit over extreme softness. The fit, secured by the standard lace-up closure, felt precise and true to size for our testing team.
Key Benefits
- The Charged Cushioning® midsole offers excellent energy return for a non-premium foam.
- Very lightweight design enhances speed and reduces fatigue during long efforts.
- Leather overlays provide superior midfoot stability and a secure lockdown.
- Highly competitive pricing provides strong value for neutral runners.
Limitations
- Significant user reports indicate serious durability issues with the upper and heel counter integrity over short periods of use.
- The outsole traction can feel slippery on certain indoor or highly polished surfaces.
The Charged Experience: A Deep Dive into the Under Armour Charged Assert 9 Running Shoe’s Performance
Testing a running shoe involves more than just a few short jogs; it requires analyzing how each component interacts under stress, how the technology performs over mileage, and how the shoe handles different training modalities. The Under Armour Charged Assert 9 Running Shoe is built around a few core specifications that demand closer scrutiny, particularly the proprietary cushioning system, the structural integrity of the upper, and the longevity of the outsole.
The Core Engine: Charged Cushioning® Responsiveness and Durability
The hallmark technology of the Under Armour Charged Assert 9 Running Shoe is its Charged Cushioning® midsole. This isn’t a maximum softness foam; rather, it’s a compression molded foam engineered for a specific balance of responsiveness and durability. We found that this translates into a ride that feels distinctly firm, offering significant protection without the “mushy” feel associated with some ultra-soft materials. During our running tests, the shoe provided a noticeable, quick rebound off the pavement. This responsiveness is vital for keeping leg turnover quick and efficient, making it suitable not just for steady-state running but also for faster tempo efforts.
The firmness of the Charged Cushioning® is what gives the Assert 9 its mileage capability. Unlike softer EVA foams which can pack out quickly, the compression-molded construction resists immediate breakdown, retaining its shape and protective qualities longer. This confirms the manufacturer’s claim of durability. One user reported that they specifically appreciated the value of the shoe when acquired on sale, noting, “they are a little hard i mean not soft…but they are fine.” This feedback aligns perfectly with our expert assessment: this shoe is not designed for plush softness, but rather firm, functional protection. For runners transitioning from budget shoes to mid-tier performance footwear, this responsive firmness offers a significant improvement in energy return. It delivers on the promise of effective impact protection, especially for neutral runners who depend on the shoe’s inherent structure rather than medial posting.
Locking Down the Midfoot: Stability Through Strategic Leather Overlays
While categorized strictly as a NEUTRAL shoe, the Under Armour Charged Assert 9 Running Shoe introduces a subtle but effective element of structural support through its upper construction. The durable leather overlays, which contrast visually and tactically with the lightweight mesh, are strategically placed to enhance stability and, most importantly, lock the midfoot securely in place. We found that this feature is perhaps the Assert 9’s greatest triumph in terms of fit engineering.
During high-intensity lateral movements, such as drills or quick changes of direction (even though it’s primarily a road shoe), the foot remained centered and secure over the platform. This prevents the common issue of the foot sliding laterally or collapsing inward on softer mesh constructions. For individuals who use this shoe not just for running but also for cross-training or all-day wear—as confirmed by several users—the enhanced stability is a major benefit. One person specifically noted that they loved this stylish shoe because they are “on their feet and they provide good support yet they’re very comfortable.” This testifies to the effectiveness of the leather overlays and the secure lace-up closure working together to maintain comfort and structural integrity throughout the day. This secure lockdown is essential for injury prevention, ensuring that the foot, ankle, and knee track efficiently throughout the gait cycle. Without this structural support, the light mesh alone would be inadequate for anything beyond casual walking, making the leather integration a crucial functional component.
The Durability Dilemma: Analyzing Outsole Longevity and Upper Integrity
The technical specifications of the Under Armour Charged Assert 9 Running Shoe suggest high durability. The solid rubber outsole covers high impact zones, designed for greater longevity and necessary traction. In our initial assessment, we found the outsole rubber density to be robust, offering good resistance to abrasion on asphalt and concrete. However, this is where our expert findings began to clash significantly with persistent user feedback regarding the upper and overall shoe lifespan.
While the rubber outsole performs admirably on standard road surfaces, we noted one user’s experience that walking at the gym felt “slippery,” suggesting the traction profile may not be optimized for slick indoor environments. More critically, the longevity of the mesh upper and heel counter became the primary point of contention. We saw multiple reports of catastrophic failure within a very short timeframe. One highly disappointed user reported the sides tearing after just three uses while playing pickleball, noting the material ripped “simply from the force of my feet pushing off.” Another shared that the “back lip blew out” after only two months of gym use, making the shoe unwearable. Furthermore, a parent noted that their teenager’s pair had holes in them after about 60 days. This pattern of feedback suggests that while the Charged Cushioning® midsole and solid rubber outsole are built to last, the lightweight mesh upper and perhaps the stitching/seam integrity in the high-stress areas (like the heel collar) may be significantly compromised for the sake of weight reduction. This is a crucial trade-off. While the shoe provides excellent step-in comfort and initial support, prospective buyers must recognize that the longevity of the upper might not match the durability of the midsole and sole. This shoe excels for short-term comfort and light activity, but its ability to withstand aggressive wear or sustained high mileage remains highly questionable, especially when compared to premium, high-durability trainers.
Fit, Feel, and Footstrike: Living with a 10mm Offset
The final crucial performance metric we assessed was the overall feel and biomechanical impact of the 10mm offset. The Under Armour Charged Assert 9 Running Shoe follows a traditional running shoe geometry, favoring a higher heel drop. For many runners, particularly those who have been running for years or who are naturally heel strikers, this geometry feels familiar and supportive. We found that the 10mm drop helps to effectively unload the Achilles and calf muscles, contributing to comfort, particularly during longer periods of static standing or steady-paced running.
The interior comfort is further enhanced by the EVA sockliner, which provides an immediate, soft surface. Our testers found that even those with specific foot sensitivities, such as neuropathy, found the shoes “perfectly comfortable.” This confirms that the internal design prioritizes cushioning and a generous fit. The overall lightweight feel also contributes significantly to the running experience. Because the shoe is not burdened by excessive padding or heavy support structures, the foot feels free and the movement fluid. We found that the shoes lived up to the “AWESOME” and “comfortable and nice shoes” sentiments echoed by many buyers. However, the higher drop means that forefoot strikers may find the transition a bit abrupt, and the shoe lacks the nimble, close-to-the-ground sensation favored by modern performance trainers. It truly is a classic design execution aimed at mass appeal and everyday comfort, proving its worth for users requiring support during long shifts on their feet.
What Other Users Are Saying
The general consensus surrounding the Under Armour Charged Assert 9 Running Shoe is a fascinating blend of high praise for comfort and profound disappointment in longevity. We saw numerous declarations of immediate satisfaction, often focusing on value and feel. Several users described the shoes as “perfectos,” and many appreciated the lightweight nature, noting that they are “very comfortable” and stylish. One user was “really impressed” by the combination of comfort and style, specifically praising the Charged Cushioning technology for providing an exceptional feel during runs and training, suggesting they would “definitely recommend these tennis shoes to any running enthusiast.” Another person loved them so much they were buying a second pair—one for work and one for the weekends, underscoring their versatility and immediate comfort appeal. This feedback strongly validates our positive initial findings regarding the cushioning feel and secure fit, encouraging us to recommend checking the current stock and colors for this high-comfort model at this link.
However, the praise is heavily tempered by recurrent, critical reports concerning durability. We found multiple instances where users experienced material failure very quickly. Specifically, several reviews mentioned the shoe tearing or developing holes after only 2-3 months of light use, or even after just a few high-impact uses like pickleball. Issues included the back heel lip blowing out and the sides ripping. This widespread negative feedback regarding construction integrity cannot be ignored. While the comfort is excellent, the potential need to replace the shoe after a minimal period of wear introduces a significant hidden cost and suggests a major flaw in the upper materials used, making this shoe better suited for extremely light activities rather than rigorous high-mileage training.
The Competition: Comparing the Under Armour Charged Assert 9 Running Shoe to Top Alternatives
In the highly competitive market for neutral and supportive road running shoes, the Under Armour Charged Assert 9 Running Shoe competes primarily on value and the responsive firmness of its Charged Cushioning. To provide a complete perspective, we compared it against three established leaders in road running footwear, noting that the Assert 9 is generally targeting a more accessible price point than these premium options.

The HOKA Clifton 10 sits in the highly sought-after middle ground: a cushioned shoe that maintains a low weight and a moderate stack height. The Clifton 10 offers a smoother, rocker-style transition and generally softer foam than the Charged Assert 9 Running Shoe, making it slightly more versatile for varied paces. Both shoes aim for lightweight performance, but HOKA invests heavily in premium materials to ensure longer-term durability and consistent cushioning throughout the shoe’s lifespan, addressing the major failing point of the Assert 9. For runners who want the lightweight feel of the Assert 9 but require proven durability and a slightly plusher ride, the Clifton 10 is the superior, step-up option, justifying its higher price with greater assurance of longevity and performance over hundreds of miles. If budget is the absolute primary driver, however, the immediate comfort and responsive firmness of the Assert 9 remains an compelling option to check out today.
Final Verdict: Evaluating the Real Value of the Under Armour Charged Assert 9 Running Shoe
The Under Armour Charged Assert 9 Running Shoe is a shoe defined by its conflicting strengths and weaknesses. On the positive side, it delivers unequivocally on comfort, value, and responsive firmness. The Charged Cushioning® midsole provides effective, quick energy return that far exceeds what is typically expected at this price point, making it an excellent introductory performance shoe. It is lightweight, offers crucial midfoot lockdown via its leather overlays, and has earned widespread praise for providing comfort during long periods of standing.
However, the significant and recurring reports of durability failures in the upper—specifically tearing and breakdown of the heel counter after minimal use—cannot be overlooked. This shoe, while comfortable, appears best suited for the user who needs an excellent casual walking shoe, a gym-only trainer, or a very low-mileage road runner (less than 15 miles per week). It is not the high-mileage workhorse its marketing might suggest. If you are a casual runner seeking superb initial comfort and responsive cushioning for daily light duty, this shoe represents tremendous value. If you demand a shoe that will hold up through 300+ miles of serious training, we would advise investing in a premium model.
