An element in the sole of Saucony running shoes. It takes the form of a moulding in the metatarsal area, the purpose of which is to roll the foot forward smoothly. This allows the runner to feel the support of the movement regardless of speed.

A three-dimensional running shoe design from Saucony that provides a personalised fit to the foot. The concept is based on a three-dimensional fit: the cradle-shaped sole adapts to movement, the foam midsole provides comfort and cushioning, and the extremely flexible upper wraps the foot.
