Simplify's take

What believers are saying

  • Dephy expanded Sidekick on August 6, 2026, covering women’s 4 through men’s 16.
  • The August 27, 2026 starter pack page shows shipping within 15 business days.
  • Nike named Dephy a robotics partner for Project Amplify, validating its ankle-actuation leadership.

What critics are saying

  • Sidekick costs $4,500, excluding many consumers and slowing mass-market adoption in 2027.
  • If Nike Project Amplify or a larger rival ships first, Dephy loses category ownership.
  • The company’s wellness positioning avoids medical reimbursement, limiting enterprise and clinical demand.

What makes Dephy unique

  • Sidekick is the only ankle-powered consumer wearable shipping in the U.S. today.
  • Dephy’s MIT biomechatronics lineage and 40 hardware iterations create deep gait-specific know-how.
  • TÜV ISO 13482 certification and 20-stride learning give the product credibility and usability.

Dephy expands Sidekick footwear line with wider fit option for MIT ankle-powered walking tech

Dephy has expanded its Sidekick footwear line with a new design for standard-to-wide feet, broadening access to its ankle-powered walking technology. The system now offers two shoe designs covering sizes from women's 4 through men's 16. The Sidekick is the only powered footwear system built at the ankle, based on over a decade of MIT biomechatronics research. It delivers adaptive assistance during push-off, learning each user's gait within 20 strides. The expansion addresses a common challenge among the product's target users. Many conditions affecting walking and natural ageing tend to widen feet over time, making proper footwear fit essential for accessing powered walking technology. Both shoe designs feature a carbon ground reaction plate that transfers powered force from the ankle device through the foot to the ground. The Sidekick is TÜV certified for ISO 13482, the international safety standard for personal care robots.
