One iWalk product is the BiOM Ankle System, which emulates an individual’s calf muscles and Achilles tendon function to provide powered plantar flexion; that helps people with limb loss move with a natural gait by using the same metabolic energy as a non-amputee, iWalk said.

The company was founded in 2006 by Dr. Hugh Herr, director of the Biomechatronics Group at the MIT Media Lab.
