Intended Use
The Aeris Activity posterior-mounted, prosthetic foot is intended for use in lower
extremity prostheses. The foot uses a long carbon pylon to maximize energy storage
and release during gait. The first high-energy-return, multiaxial foot for amputees with
Syme or Boyd amputations, the Aeris Activity accommodates the minimum clearance
required for long transtibial amputations without compromising the function.
Indications
• Moderate to high activity transtibial amputees as defined by functional K3 and K4
activity levels
• Unilateral or bilateral patients
• Patients that would benefit from high energy return
• Patients that would benefit from low build height
• Patients weighing up to 275 lbs. (125 kg)
Contraindications
• Clearance below: Build height for sizes 22 – 24: 1.5 in. (3.8 cm),
Build height for sizes 25–30: 1.75 in. (4.4 cm)
• Patients weighing over 275 lbs. (125 kg)
• Transfemoral amputees
The device is intended for single patient use only.

• Patient weight: Up to 275 lbs. (125 kg)
• Foot weight: 17.6 oz. (500 g)
• Build height for sizes 22 – 24: 1.5 in. (3.8 cm)
• Build height for sizes 25 – 30: 1.75 in. (4.4 cm)
• Functional level: K3-K4
• Durable; meets ISO-22675 standard

Storage and Handling
It is recommended that prosthetic feet be stored in a cool, clean, dry environment
away from harsh chemicals (chlorine, acids, acetone, etc.).
