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 Head Vi-Pod. This heel cushioning insert is combined with the brand's Energy Bridge and CXG Comfort Grid technologies for a fully-loaded underfoot setup with plenty of impact protection.

What is it? A heel cushioning unit designed to dampen and absorb energy. Head Vi-Pod is part of the brand's Trienergy system, which combines the heel Vi-Pod cushioning with mid-foot Energy Bridge and forefoot CXG Comfort Grid. The three technologies work in unison to deliver cushioned protection and energy return on the courts.

How does it work? Head Vi-Pod technology works by absorbing impact where it strikes most, the heel area. Vi-Pod helps to eliminate vibration and transfer the energy forward for maximum propulsion. From there, the supportive Energy Bridge carries the power to the responsive CXG Comfort Grid cushioning in the forefoot.
