Cheetah® Xtend

Cheetah® Xtend


Kick into high gear with a responsive and comfortable ride from start to finish.

The Cheetah Xtend is the perfect companion for longer sprints and short-distance running (400-5000m). This highly effective carbon fiber blade has a continuous curve toward the toe offering a smooth rollover. The 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 off the blade.

Cheetah® Xtend™ 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.
