From the Golden Goose website: After studying and researching the best technologies on the market, we decided to make the Purestar sneakers top performing, elevating the idea of everyday sneakers. Every single element of this women’s model was created in optical white, without forgetting the Golden Goose star on the side of the upper and the 3D logo on the heel tab. The design remains faithful to our philosophy and retains all of the details that have always made our sneakers special. You will feel the revolution from the very first moment you put them on.
