What does the ultimate slip-on look like according to style icon Nick Wooster? Well, first you enlist the help of the sneaker experts at Greats and then you wrap it in a glorious upper of Bison leather. Not just any Bison leather either, Wooster looked to his friends and collaborators at Parabellum to get some of the best leather out there.

The sneakers are handmade in Italy with a stitched sole and tone on tone upper is finished with a bison leather heel tab that features Parabellum's signature technical ceramic buttons in white. 

The sneakers are now available for pre-order for $380 at Greats.com.
