Movement, Your Way.
The Sidekick is a powered footwear system built for people who'd rather be outside than sitting still. Like pedal assist on an e-bike, it gives you a gentle boost with every step — so the last mile of a hike feels like the first, a long day out doesn't wreck you for the next one, and "how far can I go?" stops being the limiting question.

How it works
What does the Sidekick do?
With every step, your ankle naturally points down and pushes off the ground as you plant your toes — that push is what moves you forward. The Sidekick gives that motion a small, precisely timed boost: a gentle lift at the back of your heel, right as your foot pushes off.
Most people compare it to stepping onto a moving walkway at the airport, or getting a push on a swing — a little extra momentum, exactly when you need it.
Does the Sidekick move you, or move with you?
The Sidekick doesn't move for you — it moves with you. If you stop walking, it stops too; it's not going to carry you forward or push you anywhere you're not already going.
What it does do is stay ready for when you re-engage: as you push off into your next step, the Sidekick is there to support it. Power levels are easy to adjust on the fly, so a tougher stretch of trail or a tired-legs kind of day doesn't have to be the reason you turn back early.
SAY YES TO MORE
Take more steps, enjoy longer days, adventure as you want to.
Walking is the easiest habit to build a healthy, active life around, until fatigue or soreness cuts your day short. The Sidekick adds a natural lift to every stride, so you can walk farther, stay on your feet longer, and still have legs left for tomorrow.
The Sidekick
A gentle boost that scales with whatever you take on.
And we can hear the question now: "Will this make me lazy or weak?"
The simple answer is: no. Because the Sidekick unlocks that "yes and" mentality - go that extra mile, recover faster after a long run or heavy lift, or take that 20,000 step day in a new city without worry.
The Sidekick works with your stride, not for you: you stay in control, and the Sidekick adds support exactly when it matters.
The Sidekick is a wellness product, not a medical device. Product shown in video is Sidekick 1.0.

Powered at the ankle.
Most exoskeletons or support devices target the hip or knee and that makes sense on the surface, since those are the joints where people feel discomfort or fatigue radiating from. 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 whether the challenge is in your hips, knees, or ankle, the most effective place to deliver support is at the source of that energy.
It works with your stride.
The Sidekick is a powered footwear system that reduces the effort your body spends on every step so you can walk farther, hold your pace longer, and recover with more in the tank. You feel the power and support after 20 training steps; no complicated set up process or confusing user experience.
Strap in, power on, go.
No app. No learning curve. Comfortable enough for a walk around the block or a full day on your feet.
