Pro-flex Xc Foot, Available Sizes : 22-27cm

The Pro-Flex XC foot reduces the need for the user to actively push the body forward and helps to equalize stride length. It allows for forward progression of the limb, reducing impact to the joints for ultimate comfort and ease.
As with all Pro-Flex devices, it features our proprietary 3-blade design with full effective toe lever and a more anatomical split toe. In addition, Pro-Flex XC includes a lightweight foot cover featuring a grippy sole for barefoot stability on wet, slick surfaces. It is easy to clean, adapts to a range of footwear and has a natural arch and footprint.
Pro-Flex XC was developed to comfortably accommodate relatively active users, who enjoys hiking and jogging, as well as level-ground walking. Comes with an aesthetically pleasing, anatomical footcover and integrated male pyramid. Pro-Flex XC is rated Waterproof, which means it is fully resistant to both chlorine and salt water submersion.
A weatherproof device allows use in a wet and/or humid environment but does not allow submersion. Fresh water splashing against the enclosure from any direction shall have no harmful effect. Dry thoroughly after contact with fresh water. Fresh water: Includes tap water. Excludes salt and chlorinated water. For a weatherproof system, only weatherproof components must be selected.
Proportional response
The layering of carbon fiber optimizes the deflection of the forefoot from mid-stance to toe-off and is proportional to the user’s weight and impact level.
Full length toe lever
The full-length keel/toe lever matches the length of the sound foot, giving a smoother, symmetrical gait.
Active tibial progression
Vertical forces generated at heel contact are initially absorbed and translated into forward motion described as Active Tibial progression.
