Before wearables came onto the scene, only Olympic athletes had access to real-time analysis of their workouts. Now, your average Joe can strap on a fitness band or pop on a smartwatch and get a breakdown of his entire workout. There’s also an entire industry based on high-tech clothing that can measure your fitness activity. Sensoria is one company that focuses exclusively on fitness gear that uses tech to help people improve their health and reach their fitness goals.

“You’re not wearing anything else, but whatever you wanted to wear that day — just a t-shirt, a pair of socks, and a pair of shoes.”

We sat down with Sensoria CEO Davide Vigano to talk about the company’s brand-new Fitness Socks and electronic anklet for runners. The company has a grand vision for the future of wearables, and truly thinks the emerging category will change the way we look at health and fitness.

Previously, Sensoria introduced a high-tech sports shirt and sports bra for runners who want to monitor their heart rate and other metrics during their workouts. Now, the company is moving on to another part of the body: your feet.

Anyone who’s ever been a runner knows just how easy it is to get injured, or simply run with bad form. Sensoria’s Fitness Socks and the accompanying anklet aim to solve this problem. The socks feature high-tech pressure sensors that are woven into the fabric, so you can’t feel them at all. They look like a normal pair of ankle socks, at first glance. Vigano told us that the socks are rated to go through 60 wash cycles before they wear out, but the company is working to improve that number. Nonetheless, since the $200 Sensoria Fitness Socks Bundle comes with four pairs of socks, the anklet, and the charger, Vigano thinks its well worth it. Also, once your socks have worn out, you can simply buy a three-pack for $60.

The anklet looks like a small, crescent-shaped band. It is made of flexible rubber and curves along with your ankle. Only the central part where the battery and sensors are located is rigid. The one we saw was an early prototype, though, so it will probably look more polished and thin when Sensoria officially launches the product at CES 2015. The anklet connects to the socks via conductive metal snaps and lights up when you first put it on. There is no power button — you just start moving to activate the sensors. The Bluetooth-enabled anklet sends data from its own sensors, as well as those from the socks, to the Sensoria Fitness app on your smartphone.

You can tell the app how you want to run, whether you aim to heel strike or land on the ball of your feet, a distance goal, and your ideal cadence. The app is a real-time analysis tool, so it can even give you suggestions. For example, if you start to drop your cadence or keep on heel striking when you meant to land softly on the balls of your feet, the app can tell you how to fix it and get back on track. You can listen to your music during your run, and the coach will only interrupt your playlist if you want help.

The main page of the app shows a diagram of your feet, which lights up with different colors, based on the data it receives from the sensors. If you’re hitting the ground with your heel, the point of greatest pressure turns yellow and the surrounding areas go orange, pink, and red. The parts of your feet that aren’t exerting pressure on the ground will appear blue or purple. You can see how the colors change based on your foot’s position in real time.

Additionally, the app collects altitude and GPS data from your smartphone and accelerometer info from the anklet. When you wear the anklet on one ankle, you only get data from that foot, but you can pair a second anklet with the app, if you need data from both feet simultaneously. However, Vigano says that one anklet still works for cadence, and you can switch back and forth, during the day if you want data from both feet. The app can pair with other smart fitness wear, too, including Sensoria’s own sports shirt and sports bra, to give you heart-rate data and more.

The app also lets you choose between 7,000 different running shoes in Running Shoe Closet, to help you estimate the mileage of your shoes, so you know when to replace them. Later, when you’re done running, you can see all your data on the Sensoria Fitness app on your smartphone or tablet. You’ll be able to look back at your run and analyze your performance mile after mile, as well as compare it to previous workouts to see your progress. Vigano says it’s almost like looking at an instant replay.

Sensoria says the anklet’s built-in battery can last up to seven hours, so you can either wear it during the entire day or just during your daily hour-long run. If you only use it for an hour each day, it should last seven days before it needs a charge.

However, the best part about Sensoria’s wearable tech is that it’s completely inobtrusive. You tuck the anklet under the sock and it’s nearly invisible. The shirt and sports bra hide the tech even better. That’s just part of Sensoria’s mission, says Vigano.

“You’re not wearing anything else, but whatever you wanted to wear that day — just a t-shirt, a pair of socks, and a pair of shoes,” Vigano told us. “We want to take away stuff, not add stuff. At some point the electronics are going to be woven into whatever we wear.”

I’ve used the Apple Watch Series 8 for four years. The Series 12 finally made me want to upgrade
After four years with my Series 8, Apple finally gave me enough reasons to put my old watch out to pasture.
Apple Watch series 12 on wrist

I've used the Apple Watch Series 8 for four years, and I never felt the itch to upgrade. Sure, newer models added faster chips and neat tricks like the double-tap gesture, but nothing felt big enough to convince me to spend the money and start over with a new watch. I was happy with what I had.

That changes with the Apple Watch Series 12. It brings a mix of hardware and software upgrades that make it one of the best Apple Watch releases in years, and the best part is that it still starts at $399. Here's why I'm finally ready to move on from my Series 8.

Google may have a fitness tracker in the works with a display and Wear OS
It could be the Fitbit Charge 6 successor
YouTube Music controls on the Fitbit Charge 6.

Google may be preparing a successor to the Fitbit Charge 6, and it could bring a major software change to the fitness band. A mystery device identified as G8BL6 has appeared at the FCC with Bluetooth LE, built-in GNSS, and what appears to be a display. 9to5Google believes the device could run Wear OS and says it would make sense as a successor to the Charge line.

The Charge 6 has not been refreshed since 2023. Google also showed an unidentified fitness band in Pixel 11 ads in August. The device had a tall display and looked closer to a Fitbit Charge than a Pixel Watch. Google never identified it, but the FCC device could be the same product.

Apple’s best use of AI isn’t happening on the iPhone
Apple Watch understands AI better than the iPhone
Apple Watch Series 12 Audio Intelligence

AI is constantly being shoved in our faces. From your laptop to your phone, every new gadget now ships with some features built around AI. Over the last couple of years, even Apple has tried to make Apple Intelligence sound like the next big thing on the iPhone.

With iOS 27, the argument finally became worth listening to. Siri AI is a great example of this. It can search through personal information and understand what is on your screen before answering specific or broader general questions. Visual Intelligence looks through your phone's camera to understand what you're seeing, and a lot more.
