This color way of the Nike SB has been created in collaboration with Premier and is winter ready. The sneaker sports a Charcoal Grey Upper with Graphite and White accents. There is synthetic wool present and the sneaker is inspired by the Petoskey stone, hence the name. 3M laces, the back panel of the shoe featuring the stone’s print and an icicle вЂP’ embroidery on the heel finishes up this unique collaboration.
