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 adidas Torsion System. This outsole component has been a mainstay in performance adidas models since its introduction in 1988.
What is it? A thermoplastic arch support designed to allow the forefoot and rearfoot to move independently and adapt to running surfaces without straining the foot through excess motion. Torsion excels by allowing the midfoot to naturally adjust to the ground and offering high levels of support and stability which are suitable for a range of sports.
How does it work? Think of the Torsion System as a lightweight bridge between the forefoot and heel. By supporting the midfoot, Torsion System serves as a platform which helps to combat improper flexing of the arch. This is beneficial for protection, fit, and control during strides and movements. The result is a smooth heel-to-toe transition.

Bottom line: There's a reason that the Torsion System is still going strong 25 years since its debut—the unique setup provides arch support for running, lateral support for tennis players, and explosive stability for basketball enthusiasts.
