WHAT IS IT
Bionic footwear built for everyday life
Your ankle produces up to 50% of the energy you need to walk, which makes it the most effective place to add power for everyday movement.
- 1A carbon fiber plate in the shoe carries the extra push into your step.
- 2The robot clips onto a cleat at the heel of the shoe.
- 3The robot straps to your shin.
The robot and shoes work as one, so you go farther than your own legs would take you.
123Shoes includedWhy the ankle?
The Sidekick powers the joint that does the most work when you walk.
Easier on your joints
The Sidekick takes over 100 pounds of load off your joints each step.
Simple to wear
The Sidekick goes on in under two minutes, so you spend less time gearing up and more time exploring.
More time moving. More life in every step.
How It Works
Put it on
Clip the robots onto your Dephy shoes and strap them to your shins.
Power on and walk
The Sidekick learns your stride over 20 unpowered steps.
Feel the push
It feels like a push on a swing, right as your foot leaves the ground.
Stay in charge
The push comes at the right moment in your stride and stops when you stop.
After a few minutes, most people barely notice the push as their body adapts.
