KNOW YOUR TECH breaks down the scientific technology used in your favorite sneakers and activewear. Let’s demystify your next purchase: today’s technology is On's CloudTec. As the driving force behind the up-and-coming Swiss brand's running sneakers, CloudTec is used on all of On's models. By modifying the traditional cushioning setup, CloudTec offers a unique and fresh ride.

What is it? On's CloudTec is a cushioning system made up of hollowed tubes. Known as "Clouds", each tube works as a "tiny stability ball," offering a responsive feel through the entire gait. Designed to enhance the use of postural muscles and provide a natural, stabilized foot strike, CloudTec mixes barefoot minimalism with protective heel cushioning.

How does it work? As a runner strikes the ground, CloudTec's highly adaptive rubber tubes cushion vertical and horizontal impact for a protected landing. As the foot beings its transition, the Clouds tighten to provide a minimal, barefoot-like toe-off.

Bottom line: While On's CloudTec is reminiscent of previous cushioning configurations, its unique balance of heel impact protection and minimal toe-off separates it from the pack.
