Mobius X8 Knee Braces

The Mobius X8 Kneebrace evolved from 7 years of development, prototypes, and testing. The design of the Mobius brace is intended to prevent three typical knee injuries: lateral bending, lateral rotation and hyperextension.

The hard nylon shell is supplemented by the Continuous Cable Routing System (CCRS). It is a continuous cable loop in a figure-eight configuration that loops around the knee joint. The CCRS tightens when forces are applied to the knee joint. In turn, the brace shells tighten also, to keep the knee firmly in place.

The cable’s beginning tension is adjustable with a dial large enough to turn easily, even through a pair of pants. The straps that hold the brace in place are also adjustable and replaceable.

Another notable feature of the Mobius X8 is that the front of the knee is never exposed. The brace’s panels are articulated, and even with the knee bent, the pieces overlap.

Features:

  • CCRS (Continuous Cable Routing System) adjusts the fit with a single turn of the locking CNC forged 6061-T6 anodized aluminum dial
  • Plush molded EVA foam and impact absorbing rubber internal padding
  • Overlapping patella area with zero degree CNC forged 6061-T6 anodized aluminum stop leaves no gap exposed regardless of how far the knee is bent
  • Figure-8 cable and behind-the-knee adjustment pad greatly strengthen the joint yet work as freely as your body's own ligament system
  • CNC forged 6061-T6 anodized aluminum hinge plates
  • Lightweight PIM glass-filled nylon shell conforms to your leg shape, creating 360-degree protection that will not rotate or slip
  • VELCRO® brand closures straps with TPR pull tabs numbered in order to provide proper fit and easy entry and exit (replacement straps sold separately)
  • Sold as a pair

How to Measure

Fitment Notes & Exceptions
  • If you fall between two sizes, choose the smaller size
  • If the #2 Tendon Back Plate contacts the shells and will not tighten any further, the brace is too large for you. Using an X8 that is too large for you will not function as designed and will not protect you properly. It may also cause premature wear of the device and may void the warranty
