Sidekick Starter Pack
The Sidekick is the world's first wearable, powered at the ankle, designed to help people move with more ease and confidence in everyday life. Paired with two shoe options, the Dephy Active or the Dephy Comfort.
Dephy Active: For a supportive, responsive feel that fits like a performance athletic sneaker. Best for narrow to standard feet.
Dephy Comfort: For a cushioned, bouncy feel that fits like a casual everyday sneaker. Best for standard to wide feet.
The Sidekick is the world's first wearable powered at the ankle, that gives you a boost at the heel with every step you take. Think of it like an e-bike for walking. Built on more than a decade of development, it's designed for everyday use: lightweight, intuitive, and engineered to help you move farther, faster, and with less effort.
The Sidekick isn't a medical device. It's a lifestyle and wellness product that powers your movement so you can move with more ease, confidence, and joy.

Two shoe options for your Sidekick experience. One purpose: more power in every step.
Dephy Active and Dephy Comfort both feature a carbon fiber plate, built to work with your body's natural efficiency as you walk. The difference is the ride. Choose the feel that matches how you move every day.
With two shoe options, there are more ways to make movement feel good.
Slip on and lace up your compatible shoes, then attach the Sidekick to your shoes by engaging the magnet on the Quick Connect. Rock the Sidekick forward until you hear and feel it lock into place on each shoe. Finish by securing the calf strap around your leg.
Pop in the charged batteries and hold the battery button down to turn your Sidekick on. Stand still until you feel a gentle squeeze on both shins.
Walk naturally in a straight line for about 20 strides across flat ground. Your Sidekick system will learn your rhythm—and from there, enjoy comfortable, powered movement that adapts to you.

Absolutely! The Sidekick system is the perfect travel companion. Some of our early customers have taken their devices to Italy, France, Disney World, and on a cruise! As the Sidekick system is powered by lithium polymer (LiPo) batteries, you will need to follow standard airline regulations for LiPo battery transportation. Make sure to carry them in your hand luggage when flying so your Sidekick is ready to go wherever you are.
