The Nike Free RN CMTR 2018 PRM 'Sail' sneaker revamps the design with hits of ‘Dark Russet,’ adding elevated style details to the versatile silhouette. Made from a stretch knit fabrication, the shoe takes on a snug, sock-like bootie construction, with a wide webbing overlay that wraps the midfoot. An adjustable toggle and hook closure incorporated within the lacing system allows for a custom fit and helps the silhouette transform from a running shoe to a casual lifestyle sneaker and back.
