Question: Is the RUSH™ Foot nearly indestructible?

Yes, the RUSH™  Foot is made from a unique space-age material.   The material is a  glass composite material that is extremely flexible and durable, thus making the RUSH™ Foot nearly indestructible. Check out the video below that demonstrates the durability of the RUSH Foot!


Question: Does the RUSH™ Foot "soften" over time?

"No, like most other composites, our glass fiber composite does NOT 'soften' or 'relax' over a period of time, due to extended use. This issue refers to the hysteresis, or energy return of the composite."

Question: What are the key differences between a carbon fiber foot versus the RUSH™ Foot

Question: How does the RUSH™ Foot flexibility compare to carbon fiber?

Question: Does the RUSH™ Foot have a "dead" or flat spot?

No, the RUSH™Foot does not have a dead spot. The RUSH™ Foot replicates the ankles flexibility and roll through motion to create a stride with no dead spot. Our proprietary sole plate is designed without an inherent arch providing a continuous and rolling point of contact throughout the entire prosthetic step, making it the smoothest most effortless foot available on the market today.

Question: Why is the plantar flection bumper only attached to the keel/instep?

The bumper is only attached to the keel to allow the sole plate and the bumper to separate at terminal stance and toe-off.  This allows maximum toe deflection and rotation at the toe for a smooth roll-through.  It also allows the sole plate to rotate more freely for multiaxial rotation.  The overall result is a highly compliant toe-off with smooth action. 

Question: What makes the RUSH™ Foot great for all terrains?

Due to the unique design, the two composite segments are buffered by a rubber molding that prevents any abrasions from occurring. This is a result of having no bolts, screws, fasteners, or overwraps like competing feet. The majority of carbon fiber feet have multiple bolts, screws, fasteners or overwraps that allow dirt and debris to compromise the carbon fiber. These extraneous parts always create stress points that further compromises the durability of carbon fiber.

Question: Is the RUSH™ Foot waterproof?

Yes, the RUSH™ Foot is 100% waterproof. Unlike many leading carbon fiber feet that are water resistant, the RUSH™ Foot provides the ability to be fully submerged in water. This is a direct result of the radically simple design of the RUSH™ foot.  The radically simple design of the RUSH™ foot departs from the use of distal bolts, screws, fasteners, or overwraps. Unlike competitor’s feet, our composite never comes in contact with itself anywhere on the product or under any circumstances. This makes outside dirt or debris incapable of acting as an abrasive and causing any type of failure.

Question: Is the RUSH™ Foot shell available with a sandal toe?

The RUSH™  Foot shell is currently not available in a sandal toe option.  

Question: How do I maintain the RUSH™ Foot?

The unique design of the RUSH™ Foot makes it virtually maintenance-free.  If you get debris in the foot shell, a simple water rinse should suffice.
