Impulse® Foot
PrintThe Impulse Foot consists of a composite foot plate attached to a carbon/nylon keel. The foot plate is composed of the high-performing composite material used in the Pathfinder® II Foot. The foot provides high energy return, flexibility, and good toe response. Featuring a recessed keel, the Impulse can be used for endoskeletal, exoskeletal, or Symes applications. Partner the foot with the multiaxial Impulse Ankle for added stability on uneven ground. The Impulse foot carries a weight limit of up to 350 lbs (160 kg).
The Impulse Symes System includes an Impulse Symes Foot and a Symes Adapter Kit. The keel of the Impulse Symes Foot is curved at the same radius as the Symes Socket Adapter, eliminating the need for any type of interface plate and slightly lowering the clearance needed. The Symes Adapter Kit allows angular adjustments (during the alignment phase) as well as length adjustments. The Impulse Symes foot carries a weight limit of up to 250 lbs (115 kg).
