Performance shoe uses decoupled midsole
The Nano X is a lightweight trainer with a Flexweave upper, high-density foam collar construction, and increased traction on the sole. A decoupled midsole (a split heel to better absorb shock) is said to improve “runnability”, using additional cushioning for a smoother stride.
Reebok said it has listened to the “ever-changing fitness space” on the design, which is part of a decade-old line. The company has been iterating on the Nano range for ten years, based on feedback from athletes, said Tal Short, senior product manager of training footwear.
