Congratulations to all the competitors our there using the XT9 do the impossible so impressively.

ADVANCED TECHNOLOGY

Prosthetics have never received the kind of attention that’s devoted to industries like Aerospace, Formula One and the outdoor industry.  That’s why we look to these industries for higher technologies and standards.
What happens when we shoot to match their standards without their budgets?  It forces us to find innovative ways to achieve their standards at price that keeps our products accessible to people who couldn’t buy an airplane, but in many cases, it also leads to innovating new ways of doing things that actually exceed their standards.  Such is the case with the XT9air, the most advanced, carbon fiber knee frame ever created!
