Inspired by the primary-color aesthetic of artists like Piet Mondrian, the Greats Wooster Primary Pack goes back to the basics. Greats applied a trio of fundamental hues to its sleekest silhouette, the slip-on Wooster, featuring a Margom sole and elastic side tabs for easy and on off, as well as a vachetta leather lining that allows for sock-free wear (something that would no doubt be recommended by menswear icon Nick Wooster, for whom the shoe is named). This time around, the slip-on ditches the typical leather construction for rich suede, offered in Cadet, Red and Yellow colorways.
