The Archetype Brace preloads tension in the leg with every step, artificially overtaking the role of the knee in the leg, sparing your own. It effectively absorbs the impact of every run or walk up the stairs. Our patent pending offset hinge creates a mechanical advantage which makes the brace longer when extended, and shorter when contracted. Because of this, every step brings about a gentle push between the upper and lower leg, which reduces impact, and creates support.
