This shoe is a brand new addition to the Saucony Stable and it has to be one of their greatest creations to date. Theoretically it is a neutral shoe in the same sense that the Asics Kinsei is neutral with a few guidance aids built into the design. For those who have not yet used the Progrid system it centralises the foot in the shoe and spreads the forces within the midsole to support the foot throughout the midstance phase. Very clever unless you use orthosis which will render the progrid virtually useless. This shoe is light, responsive, comfortable and works well for neutral and mild overpronators. It certainly blows away much of the competition at this price point, but lets face it, its not cheap!!
