KNOW YOUR TECH: Asics Propulsion Trusstic System

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 Asics Propulsion Trusstic System. This supportive shank is implemented into the outsole of Asics running products and extends from the arch to the forefoot.

What is it? A plastic shank utilized on the outsole of Asics running sneakers which channels energy to provide a forward propulsion. A modified version of the brand’s original stabilizer, the Trusstic System, Propulsion Trusstic has been enhanced to help push runner’s forward.

How does it work? The Asics Propulsion Trusstic System works by mirroring the functions of the foot’s ligaments, specifically the plantar fascia. This transforms the foot from a flexible structure, for shock absorption through the heel strike and mid-stance, into a strong, firm lever to provide forward propulsion. As a reult, Propulsion Trusstic System helps to spring the runner forward with every stride.

Bottom line: Energy-returning outsole and midsole setups may be commonplace at this point, but the Asics Propulsion Trusstic System takes it a step further by mimicking the foot’s natural functions.
