Not a medical device
The Sidekick is not designed to diagnose, treat, or cure a condition. If you can walk and want it to feel easier, the Sidekick is can help you do more of it.
Powering your everyday movement.
Adaptive controls, integrated sensors and a brushless motor combine to add a subtle boost as you push-off with each step. Like a secondary calf muscle, the Dephy Sidekick helps you move farther with less effort while keeping your stride natural.

HOW IT FEELS
At the exact moment your foot pushes off the ground, the Sidekick delivers a gentle boost, reducing the effort your body has to produce on its own.
01 THE RIPPLE EFFECT
When walking gets hard, everything above starts compensating. Your knee works harder. Your hip flexors pick up the slack. Fatigue and discomfort - often in places that have nothing to do with your foot or ankle - happen from a walk you've always done, a day on your feet, or years of managing a condition.
02 THE CHAIN RELAXES
When the calf gets support, the knee doesn't have to overwork. When the knee isn't overworking, the hip doesn't compensate. The whole chain above relaxes.
03 THE SIDEKICK STEPS IN
The Sidekick delivers powered support at the back of the heel at exactly the right moment. The assistance feels like a natural extension of your own movement, working with you, not against you.
That's why Sidekick users report feeling the difference not just in their feet but in their knees, hips, back, shoulders, posture and how they feel at the end of the day.

What is inside the Sidekick?
Advanced technology, premium materials, carefully distilled into a streamlined, comfortable wear experience.
WHY THE ANKLE
Why the ankle, and not somewhere else?
01
THE CURRENT ECOSYSTEM
If you've seen exoskeletons or support devices before, most of them target the hip or knee. That makes sense on the surface; those are the joints where a lot of people feel discomfort or fatigue radiating from.
02
WHERE WALKING ACTUALLY HAPPENS
But the ankle is where walking actually happens. In a typical stride, the ankle generates more than half of the forward energy that moves your body ahead - it's the engine. Which means if you want walking to feel easier, whether the challenge is in your hips, knees, ankle, or just your legs feeling worn out too quickly, the most effective place to deliver support is at the source of that energy.
03
A NATURAL ATTACHMENT POINT
Above all, the ankle is the most natural place to do it. The Sidekick attaches to compatible standard footwear at your heel and straps to your shin. These two places on your body are built to handle force, so assistance feels like part of your stride, not something added on top of it.
04
WHO IT WORKS FOR
That's why ankle assistance works for such a wide range of people. You don't have to have an ankle or foot problem to benefit. People with knee or hip fatigue are well suited for the Sidekick system. If walking takes more out of your legs, and your day, than it should, the Sidekick is for you.
BUILT WITH INTENTION
What the Sidekick isn't.
The Sidekick is a wellness product, not a treatment and built to keep people moving.

Not a replacement for your stride
The Sidekick works with your gait, not instead of it. It won't walk for you which means you're always in control of when and how you walk. It delivers personalized assistance to your muscles, stride, and pace.

Not for everyone
If you're looking for a clinical intervention or rehabilitation device, please speak with a clinician first. The Sidekick is built for people who are active, or want to be.
