EQUILIBRIUM


The main characteristic of the EQUILIBRIUM foot is the spring/bumper system that generates an ankle moment and effective roll-over. A posterior spring works during load acceptance, it guarantees comfort during initial contact and allows the rollover between heel and forefoot.

Anterior bumper, joined with the ankle’s adapter, works during MID STANCE ensuring gradual rollover. The carbon fiber-glass fiber laminate generates the propulsion energy to walk during the loading of arch plantar in MID STANCE and during the loading of the forefoot in TOE OFF. 30 degree of plantar-dorsiflexion and 50% of efficiency.
Functional advantages are:
• Incremental load acceptance thanks to posterior spring. The adapter rotates backward and allows gradual forefoot contact on the ground ensuring the user’s stability.
• An effective dorsiflexion and support during mid-stance due to the posterior spring.
• Plantarflexion and propulsion release of energy guaranteed by the inferior laminate in composite materials.
• Possibility to choose the spring’s stiffness in order to obtain the right behavior requested from the user.

Equilibrium is the innovative k3 level foot (mobility key level for an amputee-patient) that offers the angle mobility of the single-axis foot and the dynamic response of the carbon fiber feet.

Material: carbon fiber and glass fiber. Warranty: 36 months.
