Cheetah® Xtreme

Cheetah® Xtreme


The blade of champions – inspired by the world’s fastest. Cheetah Xtreme is the optimal short-distance sprinting foot, a holder of multiple world records.

Designed specifically for the fast, short-distance sprints, the carbon blade features a more extreme curve than the other Cheetahs. This dynamic shape allows the foot to flex more offering a powerful energy kick. A longer, flatter toe enhances push off, while the plantar-flexed pylon supports better forward progression.

The Nike Spike Pad has been designed exclusively for the Cheetah. It provides specialized traction that has been optimized for the blade.

A new alignment adapter for the Cheetah is now available for quicker set up and easier alignment of the blade.

Cheetah® Xtreme™ Features

Active Tibial Progression

Active Tibial Progression

Vertical forces generated at heel contact are stored and translated into a linear motion described as Active Tibial Progression. This action reduces the need to actively push the body forward using the contralateral foot and also equalizes stride length.

Benefit: More natural gait and reduced walking effort.

Proportional Response

Proportional Response

The layering of carbon fiber, optimized through extensive computer analysis and mechanical testing, ensures that the deflection of the carbon fiber heel and forefoot components are proportional to the user’s weight and impact level.

Benefit: Customized construction optimizes walking efficiency thus reducing fatigue for the user.



The use of first-rate material such as carbon fiber, titanium and high-grade aluminum provides permanent protection against harmful ingress of water. Even after submersion in water, the foot’s structural parts maintain their integrity and continue to provide full support, function and durability.

Benefit: No loss of prosthetic function under wet circumstances.
