WearablesThese robotic sneakers gave me a surprising boost at CESDephy's "bionic footwear" is a walking aid for people who want to be more active.Karissa BellSenior reporterWed, January 7, 2026 at 5:45 PM UTCI'll admit that I've always kind of taken walking for granted.Other than a knee injury more than a decade ago, my ability to walk long distances has largely been limited only by my own choices.That's not the case for everyone, though.
And robotics company Dephy has created a pair of robotic sneakers, called the Sidekick, that are meant to help people who want to walk more than their bodies might otherwise be capable of.The system consists of two parts: an ankle-worn exoskeleton and a special pair of sneakers that attach to it.The exoskeleton hooks onto the back of the shoe and is secured with a strap around your calf.The battery powered device is equipped with sensors that can detect and adapt to the wearer's gait in order to deliver an extra "boost" with each step.The whole setup is pricey, at $4,500, but Dephy is betting that people who have "personal range anxiety" might be willing to pay for the extra confidence the Sidekick can provide.
"This is a device that's kind of like [having] an extra calf muscle," Dephy CEO Luke Mooney told me.I was able to take the Sidekick for a spin around the CES showfloor and it was a truly surprising sensation.The best way I can describe walking with the Sidekick powered on is that with every step forward there's a noticeable upward push from under your heel.It wasn't enough to throw me off balance, but it did feel a bit strange.AdvertisementAdvertisementAdvertisementThe Sidekick has adjustable power levels based on how much help you might need.
At the highest level, it definitely felt unnecessarily pushy.The lower levels were still noticeable but felt less disruptive.I just felt… bouncy.
Later, when Mooney turned off the power entirely, I noticed that my feet felt weirdly heavy in a way they hadn't just a few minutes before.Mooney was quick to tell me that I'm not Dephy's target demographic."A lot of times people who are fit, or like athletes, actually struggle to adopt to the technology because their body's so in tune with how they move," he said."Whereas folks who are not as physically active and fit, their body's ready to accept help."The company's technology will be used in products more focused on athletic performance, however.
Dephy has partnered with Nike on its upcoming robotic sneaker currently known as Project Amplify. Mooney declined to share details on the collaboration, but the shoemaker has claimed that some early testers have been able to improve their mile times by two minutes.I tried the Sidekick early in the day.Several hours later, though, when I was walking between the Las Vegas Conventions Center halls for the third or fourth time, I started thinking about those robotic sneakers again.I was getting close to 10,000 steps and hadn't sat down for hours.
My feet were sore.I remembered that strange, bouncy boost and thought it sounded kind of nice.
