The result of a collaboration between the US military and Ottobock, the goal was to develop a more durable and intuitive prosthetic leg to help injured service members with above knee amputations return to normal activities of daily living as well as active duty if they choose. The unique intelligent design of the X3 includes: 

Waterproof! The X3 has undergone stringent waterproof testing. Completely submersible, the X3 allows unprecedented contact with water including showering, swimming, boating, fishing and more. Ideal for patients working in or near water! 

Run, walk, run Via the remote, the X3 can switch into a larger swing phase angle suited for running and other sports. In addition, the innovative Walk2Run mode is ideal for running short distances and start-and-stop running such as across a street, down the hall or to catch a bus. In that mode, the X3 detects a walk-to-run transition and the swing angle automatically increases, with no preflexion. 

Robust and ready The X3 is “ruggedized” based on conditions an active duty military member might face and is up to the challenge of adverse and rough terrain. 

The most natural gait possible With an accelerometer and a gyroscope that is able to intuitively tell where a user’s leg is in space. These are the same technologies used in Wii™ gaming systems and smartphones and cameras and allows for a virtually natural gait. That means less worry of a stumble or fall and less concentration needed when on the move. 

Real-world mobility More physical capabilities for the real world than any other prosthetic leg including running, walking backwards, crossing obstacles in a more anatomically correct way, and climbing stairs step-over-step without massive compensating movements – ­an action that previously appeared impossible for those with above knee limb loss. 

Keep going for longer X3 offers improved battery life and an automatic "sleep" mode. That translates into five plus days of use without the need for a recharge and results in greater independence. 

5 activity modes, plus a “silencer” Programmed using a laptop and Bluetooth technology, five activity modes can be set for biking, golfing, driving, etc., and are activated using a key fob-sized remote. A mute mode is also available that silences all vibration and beep signals of the leg when needed for activities such as meetings, movies, hunting and more. 

Add an Ottobock foot Recommended waterproof feet are the 1C63 Triton Low Profile and the 1C64 Triton Heavy Duty. Other approved feet include 1C60, 1C61, and 1C62 Tritons; the 1E56 Axtion; the 1E57 LoRider®; the 1C30 Trias and 1C31 Trias+; 1C40 C-Walk®; and the 1D35 Dynamic Motion. 

The X3 carries a 3-year standard warranty with free service inspections at the 12th and 24th months.
