Dephy Sidekick
Regaining Your Stride with Powered Ankle Support
For active adults, it often starts with a quiet shift. A favorite walking path feels steeper than it used to, or the distance from the parking lot to the store seems to take a little longer to reach. With age, as the body gradually loses muscle mass, seniors may begin to withdraw from the activities that once defined their days, creating a difficult cycle to break: less movement accelerates further muscle loss, which makes walking more taxing while increasing the risk of falling. Although physical therapy remains a vital resource for improving strength and balance, motivation and consistency tend to be greater when activities like walking can be enjoyed again, or simply for longer distances.
The Dephy Sidekick is a proprietary walking shoe with a motorized arm that straps to the calf, providing a gentle forward boost at the moment of toe push-off (the instant the foot pushes away from the ground to begin each new stride). Sensors within the device measure walking speed and pattern, then calibrate the level of assistance needed to match the terrain and the user’s energy on any given day. That calibration adds up: research from MIT found that ankle-level assistance of this kind reduces the energy cost of walking by nearly 25%, meaning users can cover more ground with considerably less effort.
In daily use, the Sidekick is designed to feel more like a capable pair of shoes than a piece of assistive technology. The motorized arm detaches when not needed, and putting the full system on takes roughly 15 seconds per leg. Its adjustable design also fits users of varying heights and body types, and the shoes flex to match the full range of motion of the ankle. While the rechargeable batteries in the device provide up to five miles of powered assistance, the Sidekick is intended for seniors who can walk independently but may find that fatigue limits their mobility, rather than for individuals with significant balance difficulties or neurological conditions.
The Sidekick’s greatest value is not what it replaces, but what it preserves. For seniors who are still mobile and engaged but find that physical fatigue increasingly shortens their day, it extends the window during which they can move independently through the world, completing errands, keeping commitments, and staying connected to the routines that sustain quality of life. Rather than signaling a transition into assisted living or reduced independence, the Sidekick functions as a quiet enabler, helping older adults remain active participants in their communities for longer. At approximately $4,500 for the starter pack, it is a meaningful investment, and one that, for the right candidate, pays forward in the form of continued autonomy.
