Smart Socks Review: Sensoria Fitness Innovation

The concept of scrutinizing meticulous running data for refining one's form is admirable, however, Sensoria finds itself in need of profound introspection before its intelligent socks can justify their premium.

In myriad aspects, the integrated sensors within the smart socks do deliver on their promise of capturing more specialized data regarding runs compared to conventional fitness bands (such as cadence and foot-strike analysis). Additionally, the option to utilize a metronome for pace maintenance and to categorize workouts based on footwear choice adds to its allure, particularly for those with a penchant for alternating shoes.

However, the cumbersome clip-on anklet disrupts balance and, in my experience, detached unexpectedly with no means of tracking its whereabouts. This cumbersome accessory, coupled with the somewhat convoluted and occasionally glitchy software, impeded my initial runs, serving as the system's Achilles' heels.

Moreover, the steep price tag of Sensoria further dampens its appeal. With a starting cost of $200 for a basic package comprising two pairs of socks and the aforementioned anklet, the investment may appear excessive for a tracker primarily focused on running and walking (albeit with an emphasis on running). Additional sock pairs can be purchased at $50 each, further contributing to the financial commitment.

Prior to embarking on your run: Preparation of the equipment

Before commencing your initial run, it is imperative to ensure that you have assembled the appropriate footwear, lower leg band, and software application.

The hosiery

Should you favor the minimalist approach of running with scarcely noticeable ankle socks, brace yourself for a startling revelation. Sensoria's socks not only boast increased height but also exhibit significantly greater visibility both when worn and off the foot. Initially, they are adorned with markings indicating "LEFT" and "RIGHT," crucial for monitoring the individual performance of each foot (as one may yield slightly disparate outcomes compared to the other).

Subsequently, the underside of each sock features three sensors meticulously stitched into place -- two positioned on the forefront of the foot and one in close proximity to the heel. I can discern their presence while walking on hardwood flooring while wearing the socks. This feature is indispensable, as the sensors are responsible for meticulously mapping out your pressure points during running -- a task beyond the capabilities of a device worn on the wrist. Eventually, you become oblivious to their existence.

Fortunately, the socks boast antimicrobial properties and are entirely machine-washable. Sensoria guarantees a lifespan of at least 60 washes before the textile sensors degrade, and suggests that four pairs of socks will suffice for three or four workout sessions per week over the span of a full year. (This implies that you should anticipate purchasing an additional set of socks approximately six months after acquiring the starter kit.)

The Unconventional Anklet Tracker

Diverging from the norm of typical sensor placements underfoot, the Bluetooth-enabled anklet introduces an unusual method of attachment — utilizing magnetized studs emerging from the fabric akin to a constellation. Contrary to traditional ankle encirclement, it snugly fits around the curve of the shin. The intriguing twist? It's then concealed beneath the sock before commencing your jog. While it may not adhere to sports fashion standards, its functionality remains unparalleled.

Moreover, there's a catch. Each anklet tracks movement on a single foot, necessitating a switch of sides or the acquisition of a second device to monitor both feet simultaneously.

Measuring approximately 2.5 inches (6.4 centimeters), the rubbery strip serves as the repository for foot strike data, seamlessly transmitting it to the Sensoria app via Bluetooth connectivity. Whether equipped with one or two anklets, the process remains the same, albeit one foot at a time.

To utilize the socks, they are pulled up along the lower calf, with the ankle cuff securely fastened before folding the sock's top over the anklet. For symmetry's sake, it's advisable to repeat the process with the other sock.

Though visually peculiar, the physical sensation is less than optimal. The noticeable weight of the anklet (0.96 ounces or 27.2 grams), particularly when using only one, can leave you feeling asymmetrical initially. Nonetheless, witnessing the pressure sensors in action through the accompanying app is undeniably captivating.

It's worth mentioning the charger, featuring a USB connection on one end and a proprietary blunt-spiked ring on the other, reminiscent of a miniature spiked bracelet. A more conventional charging option, such as Micro-USB (or Type C), would be preferable to mitigate the risk of misplacing this distinctive accessory.

Sensoria assures a battery life of approximately 6 hours under continuous use, ample for completing a marathon or multiple training runs throughout the week. On standby, the battery should endure about a month, requiring approximately 1.5 hours for a full recharge.

Unveiling the Sensoria Fitness App and Its Running Experience

Before embarking on your run, ensuring the correct setup of the free Sensoria Fitness app, available for both Android and iOS, and pairing it with the anklet is essential. Initial missteps in this process can render your data-gathering efforts futile. While the app provides a tutorial for assistance, clarity within the app interface itself is paramount.

Proper setup entails pairing the anklet on either your right or left sock to the app. Additionally, you have the option to pair a heart-rate monitor if available. Creating a profile is imperative, including details such as height, weight, shoe size, and various foot- and gait-specific characteristics. This includes nuances like foot width, arch type, pronation, supination tendencies, foot rotation, and knee alignment while standing and running. Selection of shoe type is also necessary, accommodating runners with diverse footwear preferences, be it minimalist or trail-runners.

Prior to commencing your activity, you'll select the type of exercise (running, walking, etc.), specify indoor or outdoor terrain, and adjust the virtual coach's intensity level. Further customization options include activating a metronome for cadence guidance and setting distance goals. However, the predefined distance targets may limit some users' preferences.

Initiating the activity requires a simple press of the Start button, with the app indicating readiness with a ding before commencing data recording. Integration with your music playlist ensures temporary muting during voice coach prompts.

Post-run, data analysis is available through both the mobile app and online dashboard. The app displays a snapshot of statistics, with the option to delve deeper into line graphs for detailed insights. The online dashboard provides a more comprehensive view of performance over various timeframes. However, there is room for improvement in data presentation and visualization, particularly in offering enhanced graphical representations like heat maps.

Despite its potential, the Sensoria Fitness app and its accompanying hardware encounter several usability issues and limitations. Suggestions for enhancement include incorporating Bluetooth/GPS tracking for anklet retrieval, refining coaching features, expanding goal-setting options, and improving compatibility with wearable devices.

While the Sensoria Fitness system presents an innovative approach to running analysis, current drawbacks in design and functionality warrant a cautious approach. With further refinement, however, it holds promise as a valuable tool for runners seeking comprehensive performance insights.

Sensoria's Smart Socks: A Futuristic Gimmick or Practical Running Companion?

Sensoria's smart socks aim to revolutionize athletic performance, but do they really offer advantages over more conventional fitness tracking solutions like running apps and fitness trackers?

As someone who logs 15-20 miles per week running through New York City's diverse terrain, I rely on good shoes and some luck to keep me free from aches and pains. While I'm not meticulous about stretching or monitoring my form, I recognize the importance of injury prevention as I consider longer distance runs. With this in mind, I decided to explore whether intelligent textiles, starting from the ground up, could enhance my running experience.

Sensoria, known for its array of sensor-equipped clothing, including heart rate-monitoring sports bras and T-shirts, recently introduced a pair of smart socks designed to analyze your running technique. Priced at $199 for a fitness bundle comprising two pairs of smart socks, a Bluetooth anklet, and a charger, these socks promise to provide valuable insights into your running form.

However, the setup process for these socks is more involved than simply pairing Bluetooth headphones with your smartphone. You must first charge the anklet, a task requiring daily attention in my experience, then download and install the Sensoria app. Pairing the anklet with your iPhone via the app follows. Each sock is clearly labeled for the right or left foot, simplifying the process of putting them on. Affixing the anklet to the magnetic strip on the sock and securing it with extra material completes the setup. While the process may be manageable for some, it can feel cumbersome, particularly before early morning runs when every minute counts. Each sock features three textile sensors sewn in, two in the ball of the foot and one in the heel. These sensors, made of conductive fibers, function as "textile circuit boards," transmitting data to the Bluetooth anklet. Equipped with an accelerometer, the anklet detects your movement and relays this information to the Sensoria app.

The anklet boasts several functions, including step counting, speed measurement, distance tracking, calorie estimation, and analysis of foot landing and cadence during your run. While the mileage and step count are relatively accurate, the calorie count often diverges significantly from my Apple Watch, which relies on a heart rate sensor for more precise calculations. Furthermore, the anklet only transmits data for the foot it's worn on, necessitating the use of two anklets to monitor both feet simultaneously.

Despite its limitations, the Sensoria system distinguishes itself with its analysis of cadence and foot landing technique. Following my initial run, the app revealed that I landed on my heel 88% of the time—a potentially problematic habit associated with increased risk of knee injuries. Armed with this insight, I adjusted my stride length on subsequent runs, successfully reducing my heel-striking frequency to 70%.

While Sensoria offers visualization tools unparalleled by other fitness-tracking technologies, such as real-time foot pressure heat maps, their practicality during a run is questionable. Most runners stash their phones in armbands or pouches, making it difficult to access such visualizations while on the move. Additionally, staring at a screen while running detracts from the experience and undermines the purpose of using performance-enhancing tech accessories.

Concerns about the anklet's stability during runs proved unfounded, as it remained securely attached to the sock throughout my workouts. However, the socks themselves tended to retain heat, resulting in discomfort after just a few miles. While suitable for winter runs, they're less appealing in warmer weather.

The app's coaching features, including voice prompts from "Mara," offer helpful advice on improving technique. Yet, navigating the plethora of settings to customize Mara's guidance proved daunting, leading to inconsistency in the level of assistance provided. Similarly, the metronome feature designed to maintain cadence proved more irritating than helpful, especially when paired with music.

Ultimately, while Sensoria's smart socks hold promise for injury prevention and performance enhancement, they currently fall short of justifying their hefty price tag. More cost-effective alternatives, such as fitness-tracking bands and running apps, offer comparable functionality without the hassle of setup and discomfort associated with wearing smart socks. For serious runners seeking comprehensive performance insights, Sensoria may prove valuable, but for most, conventional fitness-tracking solutions suffice.


Sensoria Fitness Smart Socks offer an innovative approach to running analysis, but their current drawbacks in design, functionality, and pricing warrant careful consideration before investment. While they excel in capturing specialized running metrics, issues such as the cumbersome clip-on anklet, glitchy software, and steep pricing limit their appeal to a broader audience. With further refinement in comfort, practicality, and data visualization, Sensoria Smart Socks hold promise as valuable tools for dedicated runners seeking comprehensive performance insights.
